00:02:40,590 --> 00:02:44,30
so if you have a flexible itinerary
that's better well

41
00:02:44,30 --> 00:02:48,550
we arrive in Sydney on the 15th of April
and we were thinking of traveling to the

42
00:02:48,550 --> 00:02:50,430
Outback on the 18th of August

43
00:02:50,430 --> 00:02:55,280
up I mean a pro okay there's only one
flight from Sydney to Alice Springs on

44
00:02:55,280 --> 00:02:57,569
the 18th so I'll book you on that

45
00:02:57,569 --> 00:03:00,660
it leaves at 10 in the morning which is
quite convenient

try but two seats for you yes keys ask
your stay in the outback

47
00:03:04,840 --> 00:03:08,290

offer three packages

48
00:03:08,290 --> 00:03:14,130
budget standard and luxury the budget
package is about 500 Australian dollars

49
00:03:14,130 --> 00:03:19,450
the standard package is about 700 and
the luxury one is approximately 1,000

50
00:03:19,450 --> 00:03:22,929
though it does depend on exactly what
you would like regarding extras

51
00:03:22,930 --> 00:03:26,890
which one would you prefer well we can't
decide between the budget

52
00:03:26,890 --> 00:03:31,450
and standard options %ah well actually
just looking at my computer here

53
00:03:31,450 --> 00:03:35,160
on the date the you want to fly into
Alice Springs there is no standard

54
00:03:35,160 --> 00:03:36,430
accommodation available

55
00:03:36,430 --> 00:03:40,940
it's fully boot I'm afraid that's okay
we think that the cheapest one should be

56
00:03:40,940 --> 00:03:41,790
fine for us

57
00:03:41,790 --> 00:03:45,500

at the room options

60
00:03:53,530 --> 00:03:57,579
before you hear the rest of the
conversation you have some time

61
00:03:57,579 --> 00:04:04,579

in some special activities and trips

77
00:05:26,360 --> 00:05:28,10
while they're staying in the outback

78
00:05:28,10 --> 00:05:31,940
is there anything that interests you and
your husband yes there are several

79
00:05:31,940 --> 00:05:33,570
things we'd like to see and do

80
00:05:33,570 --> 00:05:38,520
we definitely like to visit the cultural
center yes that's very popular

81
00:05:38,520 --> 00:05:41,990
it's within walking distance of the
accommodation and it's free

82
00:05:41,990 --> 00:05:45,150
it's also a great place to pick up
souvenirs of your trip

83
00:05:45,150 --> 00:05:49,429
we were thinking about visiting one of
the nearby farms there are two farms

84
00:05:49,430 --> 00:05:50,20
nearby

85
00:05:50,20 --> 00:05:55,70
a sheep farm and a kangaroo farm there
is also an opportunity to ride camels in

86
00:05:55,70 --> 00:05:55,719
the desert

87
00:05:55,720 --> 00:05:59,419
have you been a comma before no but it
sounds like fun

88
00:05:59,419 --> 00:06:03,39
could you give me some more details
about the kangaroo farm in the camel

89
00:06:03,39 --> 00:06:03,530
ride

90
00:06:03,530 --> 00:06:07,380
certainly the kangaroo farm includes
information on how the animals are

91
00:06:07,380 --> 00:06:08,10
raised

92
00:06:08,10 --> 00:06:12,159
was the camel ride provides information
on desert flora and fauna

93
00:06:12,159 --> 00:06:15,849
which would you prefer you can arrange
to see the Kangaroos in the wild if you

94
00:06:15,849 --> 00:06:16,360
like

95
00:06:16,360 --> 00:06:20,289
rather than on a farm that sounds
perfect okay

96
00:06:20,289 --> 00:06:24,469
will go on the camel ride and see the
Kangaroos in their natural habitat

97
00:06:24,470 --> 00:06:28,320
okay on a range that for you I forgot to
mention that the journey also includes a

98
00:06:28,320 --> 00:06:29,400

the company apologizes but there can be
no exceptions to this rule

123
00:08:52,240 --> 00:08:55,600
second persons interested in these
positions

124
00:08:55,600 --> 00:09:00,600
may not have police records minor
traffic offenses like a parking ticket

125

00:09:04,29 --> 00:09:08,230
pasta mmm present drug users and sex
offenders need not apply

127
00:09:08,230 --> 00:09:13,89

00:09:36,430 --> 00:09:40,449
that they will contact these references
to confirm their genuine

00:09:40,449 --> 00:09:45,579
although all positions a volunteer the
employer will reimburse some of your

136
00:09:45,579 --> 00:09:46,540
expenses

137
00:09:46,540 --> 00:09:51,329
for example they will pay for
transportation to and from the job site

138
00:09:51,329 --> 00:09:57,120
aside from that the cost to phone calls
is covered

139
00:09:57,120 --> 00:10:01,620
before you hear the rest have the talk
you have some time to look at question

140
00:10:01,620 --> 00:10:08,620
16 to 20

141
00:10:28,640 --> 00:10:35,640
now listen and answer questions 16 to 20

142
00:10:36,19 --> 00:10:39,160
as for the positions themselves there
are three types

143
00:10:39,160 --> 00:10:43,300
the first involves assisting persons
confined to wheelchairs

144
00:10:43,300 --> 00:10:47,29
for this position volunteers must be
physically fit

145
00:10:47,29 --> 00:10:52,649
and in excellent health they must be
able to lift at least 150 pounds

146
00:10:52,649 --> 00:10:57,19
they should also have a current first
aid certificate from the red cross

147
00:10:57,19 --> 00:11:02,179
but the most important requirement is
that the volunteer must have his own car

148
00:11:02,179 --> 00:11:07,379
on Tuesday afternoons the volunteers
take their clients to various scenic

149
00:11:07,379 --> 00:11:08,779
spots around the city

150
00:11:08,779 --> 00:11:13,439
to experience and enjoy nature if you
don't drive

151
00:11:13,439 --> 00:11:16,839
but you'd still like to get involved the
center has a number

152
00:11:16,839 --> 00:11:20,989
openings for people to read to the blind
readers must

153
00:11:20,989 --> 00:11:26,429
of course read English clearly persons
with no foreign accent %ah preferred

154
00:11:26,429 --> 00:11:30,910
for these positions he must be available
on Monday mornings

155
00:11:30,910 --> 00:11:36,540
oh wait I see a note here there is one
opening for someone who can read

156
00:11:36,540 --> 00:11:40,209
her do apparently there is a Pakistani
blind person

157
00:11:40,209 --> 00:11:45,29
who'd like to hear his or her native
language but the other positions are all

158
00:11:45,29 --> 00:11:45,829
in English

159
00:11:45,829 --> 00:11:50,729
and finally there are unlimited number
volunteers needed to care for disabled

160
00:11:50,730 --> 00:11:51,790
children

161
00:11:51,790 --> 00:11:56,730
I'm sorry but the information I've been
given does not say how many children

162
00:11:56,730 --> 00:12:00,100
or what disabilities they have in any
case

163
00:12:00,100 --> 00:12:03,579
you are needed to care for the children
for one week in August

164
00:12:03,579 --> 00:12:07,279
apparently this will be at the close of
the summer holiday

165
00:12:07,279 --> 00:12:11,769
I would guess this involves helping them
with the routine chores and daily life

166
00:12:11,769 --> 00:12:14,829
again volunteers for this position

167
00:12:14,829 --> 00:12:18,49
must know basic first aid being good
health

168
00:12:18,49 --> 00:12:21,100

okay I next announcement

185
00:13:20,680 --> 00:13:24,949
is looking for someone to facilitate
tiger breeding at the London Zoo

186
00:13:24,950 --> 00:13:28,800
and get this it's a strictly volunteer
position

187
00:13:28,800 --> 00:13:32,10
that means you don't get paid had

188
00:13:32,10 --> 00:13:35,710
oh my god how I'm sorry ladies and
gentlemen

189
00:13:35,710 --> 00:13:40,850
but I just have to laugh

190
00:13:40,850 --> 00:13:44,950
that is the end of Section two you now
have half a minute

191
00:13:44,950 --> 00:13:51,950
to check your answers

192
00:14:17,149 --> 00:14:22,210
now turned to Section three

193
00:14:22,210 --> 00:14:26,680
section 3 you will hear a student called
Pete

194
00:14:26,680 --> 00:14:31,000
talking to his classmate Dave about the
presentation that he will give

195
00:14:31,000 --> 00:14:34,80
on environmental science first

196
00:14:34,80 --> 00:14:37,490
you have some time to look at questions
21

197
00:14:37,490 --> 00:14:44,490
225

198
00:15:03,410 --> 00:15:07,20
now listen carefully and answer
questions 21

199
00:15:07,20 --> 00:15:10,699
225

200
00:15:10,700 --> 00:15:15,900
are you just leaving the library now I
saw you get there at 8 a am

201
00:15:15,900 --> 00:15:21,380
yeah I've been there all day let for
they hire a cute new librarian or

202
00:15:21,380 --> 00:15:22,230
something

203
00:15:22,230 --> 00:15:25,280
I wish know is the presentation

204
00:15:25,280 --> 00:15:29,380
I will give in environmental science the
day off tomorrow watch it about

205
00:15:29,380 --> 00:15:32,550
I heard you were really excited about
the class

206
00:15:32,550 --> 00:15:35,910
and actor Shiney also called you for the

207
00:15:35,910 --> 00:15:41,100
arcane questions as he calls them it's
about environmental damage in the Yukon

208
00:15:41,100 --> 00:15:44,900
excuse me what or is that where

209
00:15:44,900 --> 00:15:49,350
you have time it's a state in Southeast
Mexico so what's happening there

210
00:15:49,350 --> 00:15:52,810
agriculture is having a really adverse
impact on the environment

211
00:15:52,810 --> 00:15:57,500
there are too many farmers doing too
much farming is restoring the forests in

212
00:15:57,500 --> 00:15:58,620
ruining the soil

213
00:15:58,620 --> 00:16:03,220
deforestation is a major problem there
now how did you learn about this

214
00:16:03,220 --> 00:16:07,730
I don't recall doctor Schnee saying
anything about it in lecture

215
00:16:07,730 --> 00:16:11,100
yes but my brother went there last month
you know

216
00:16:11,100 --> 00:16:14,990
to look at the old cities like the my
indians built that's what first got me

217
00:16:14,990 --> 00:16:15,910
interested

218
00:16:15,910 --> 00:16:19,230
your brother Tom note dick harry's twin

219
00:16:19,230 --> 00:16:22,570
anyway he told me how few trees there
were now

220
00:16:22,570 --> 00:16:27,610
and how much MT ground that grows almost
nothing he said the place look more like

221
00:16:27,610 --> 00:16:31,960
the desert the jungle in some parts it
brought environmental damage

222
00:16:31,960 --> 00:16:36,80
so I started looking for materials in
the library here look this magazine

223
00:16:36,80 --> 00:16:39,610
what's in it is an old issue of National
Geographic

224
00:16:39,610 --> 00:16:44,90
include interviews with Taurus who have
been there in the past few years

225
00:16:44,90 --> 00:16:47,940
it's pretty bad seed photos I see the
photos but

226
00:16:47,940 --> 00:16:52,210
one or two but does don't prove anything
then read the article says

227
00:16:52,210 --> 00:16:56,830
right there the first thing it points to
help Italian soil sample show is hard

228
00:16:56,830 --> 00:16:58,150
for anything to grow their

229
00:16:58,150 --> 00:17:01,590
it is held area 21,000 square kilometers

230
00:17:01,590 --> 00:17:05,490
has lost most of its poorest in the past
10 years see

231
00:17:05,490 --> 00:17:08,800
their graphs as the number of farmers
increases

232
00:17:08,800 --> 00:17:15,89
the aches a forest have decreased isn't
inverse relation

233
00:17:15,89 --> 00:17:18,509
before you hear the rest of the talk you
have some time

234
00:17:18,509 --> 00:17:25,509
to look at questions 26 to 30

235
00:17:46,840 --> 00:17:48,740
now listen and answer questions

236
00:17:48,740 --> 00:17:53,940
ends 26 to 30

237
00:17:53,940 --> 00:17:57,160
so how big is that state I'm sorry

238
00:17:57,160 --> 00:18:00,770
but I've never really learn the metric
system it's bigger than the state

239
00:18:00,770 --> 00:18:01,930
massachusetts

240
00:18:01,930 --> 00:18:05,980
that shocking anything else but lotsa
bells

241
00:18:05,980 --> 00:18:10,660
scientists say there's a growing area
about 10.56 where climate is

242
00:18:10,660 --> 00:18:14,520
when nothing can grow at all he's like
beginning a desert

243
00:18:14,520 --> 00:18:19,20
oh yes what doctor Schnee called is
certification

244
00:18:19,20 --> 00:18:24,360
but liking it anything grow their I've
never really studied soil chemistry

245
00:18:24,360 --> 00:18:27,520
I'm just trying to look into that
subject but my sister Marie is a

246
00:18:27,520 --> 00:18:28,340
geologist

247
00:18:28,340 --> 00:18:31,570
and she's the problem is that the soil
has too much saline

248
00:18:31,570 --> 00:18:34,800
with no plots helping to adjust the
chemistry apparently

249
00:18:34,800 --> 00:18:37,870
that's a common problem with floral
tights throughout the air is with rain

250
00:18:37,870 --> 00:18:38,469
forced

251
00:18:38,470 --> 00:18:41,520
once you lose the plot couple it's
difficult to bring it back

252
00:18:41,520 --> 00:18:45,920
reforestation is almost impossible even
the land is not being used for other

253
00:18:45,920 --> 00:18:46,590
purposes

254
00:18:46,590 --> 00:18:51,520
wait a minute what is saline sailing if
salt dissolved in water

255
00:18:51,520 --> 00:18:55,100
scientists who have gone there have
taken measurements but they do this by

256
00:18:55,100 --> 00:18:56,770
gathering a sample of the soil

257
00:18:56,770 --> 00:18:59,850
I'm running a simple test the shows the
ionization

258
00:18:59,850 --> 00:19:03,580
the solution the geology department you
know own University

259
00:19:03,580 --> 00:19:06,669
has reviewed the soil at the site to
there right

260
00:19:06,670 --> 00:19:10,60
it looks pretty bad the liver salinity
is going up

261
00:19:10,60 --> 00:19:14,139
but the plans would solve that problem
can be planted in soil like that

262
00:19:14,140 --> 00:19:18,20
there is a narrow spectrum of salinity
in which the plants will grow

263
00:19:18,20 --> 00:19:23,000
and once you pass the threshold there is
no way to put the problem right

264
00:19:23,000 --> 00:19:27,790
exactly it's possible the no one could
do anything to stop the train now

265
00:19:27,790 --> 00:19:31,250
or because of human greed I made a
second

266
00:19:31,250 --> 00:19:34,550
how do you know the scientists can be
trusted

267
00:19:34,550 --> 00:19:39,159
what kinda reputation do they have are
they reliable

268
00:19:39,160 --> 00:19:43,140
all that definitely reliable they
include four members at the Faculty

269
00:19:43,140 --> 00:19:46,590
from the geology department right here
MIT here

270
00:19:46,590 --> 00:19:49,800
study the photographs and check the
damage yourself

271
00:19:49,800 --> 00:19:52,830
that's what doctor horst who wrote the
book it did

272
00:19:52,830 --> 00:19:56,710
he's newly-appointed but doctor sinead
said the he's brilliant

273
00:19:56,710 --> 00:20:00,790
so where are you going now and head over
to the Geography Department

274
00:20:00,790 --> 00:20:04,360
to borrow a map my presentation you note
this whole problem could have been

275
00:20:04,360 --> 00:20:05,270
avoided

276
00:20:05,270 --> 00:20:08,610
the farmers there and you can't I'm peed
what

277
00:20:08,610 --> 00:20:12,399
go take a break leave some studying but
the rest of us

278
00:20:12,400 --> 00:20:16,230
that is the end of Section three

279
00:20:16,230 --> 00:20:23,230
you now have hoffa minutes to check your
answers

280
00:20:49,649 --> 00:20:54,290
now turned to section 4

281
00:20:54,290 --> 00:20:55,80
section 4

282
00:20:55,80 --> 00:20:58,350
or you will hear lectures introduction

283
00:20:58,350 --> 00:21:03,969
to insect biology 101 first you have
some time to look at questions

284
00:21:03,970 --> 00:21:10,970
31 to 40

285
00:21:47,280 --> 00:21:49,960
now listen carefully and answer
questions

286
00:21:49,960 --> 00:21:54,90
31 to 40

287
00:21:54,90 --> 00:21:57,509
good afternoon and welcome to insect
biology 101

288
00:21:57,509 --> 00:22:02,190
I'd like to begin this course with a few
remarks about good in sex and bad ones

289
00:22:02,190 --> 00:22:05,499
bugs are all around us and that's both
the benefit

290
00:22:05,499 --> 00:22:09,289
and annoyance sometimes maybe even
serious harm

291
00:22:09,289 --> 00:22:14,340
first let's talk about the good things
that in sex do for us

292
00:22:14,340 --> 00:22:18,590
probably the most important infect
humans and maybe for all other life

293
00:22:18,590 --> 00:22:22,689
is the be these help plants in the
process to pollination

294
00:22:22,690 --> 00:22:26,409
and of the necessary to most flowers and
fruit producing trees

295
00:22:26,409 --> 00:22:30,600
that is they carry pollen from male
flowers to female

296
00:22:30,600 --> 00:22:34,498
if it weren't for bees we have very few
food plants

297
00:22:34,499 --> 00:22:38,299
and no fruit either in fact there would
be no we

298
00:22:38,299 --> 00:22:42,168
no less a thinker than albert Einstein
pointed out that

299
00:22:42,169 --> 00:22:45,749
without bees humanity would be dead
within a year or less

300
00:22:45,749 --> 00:22:50,799
we'd stop it's that simple that should
maybe make us just a little humble

301
00:22:50,799 --> 00:22:55,470
a little less dramatic is the fact that
be he's also make the honey we eat

302
00:22:55,470 --> 00:22:59,759
moreover they produce beeswax which is
useful in candles

303
00:22:59,759 --> 00:23:02,759
and is also used as a first-rate
furniture polish

304
00:23:02,759 --> 00:23:06,289
sure these may not be vital to our lives

305
00:23:06,289 --> 00:23:09,609
but they can serve as reminders of how
important these %ah

306
00:23:09,609 --> 00:23:12,908
that's a point I keep coming back to in
this course

307
00:23:12,909 --> 00:23:17,710
though in all fairness I should point
out the butterflies Aiden pollination as

308
00:23:17,710 --> 00:23:18,559
well as bees

309
00:23:18,559 --> 00:23:22,749
now even Michigan what's the worst part
of summer

310
00:23:22,749 --> 00:23:28,440
yep that's right mosquitoes but i'm
talking about. helpful insects right

311
00:23:28,440 --> 00:23:33,609
so let's look at the Dragonfly first if
there were no dragonflies

312
00:23:33,609 --> 00:23:38,779
there would be even more mosquitoes
dragonflies mainly eat mosquitoes

313
00:23:38,779 --> 00:23:42,169
and also a few other insects yes that's
right

314
00:23:42,169 --> 00:23:47,279
they don't just fly around and they also
help to eliminate harmful insects

315
00:23:47,279 --> 00:23:51,480
so the next time you see a dragonfly
don't you dare kill it

316
00:23:51,480 --> 00:23:56,149
now let's talk a little about those
harmful insects

317
00:23:56,149 --> 00:23:59,590
take the mosquitoes I just mentioned as
an example

318
00:23:59,590 --> 00:24:03,418
not so many years ago mosquitoes here in
America

319
00:24:03,419 --> 00:24:06,529
one just annoying somewhat even deadly

320
00:24:06,529 --> 00:24:09,529
they carried malaria and yellow fever

321
00:24:09,529 --> 00:24:13,889
my own ancestor the Confederate General
John Bell hood

322
00:24:13,889 --> 00:24:19,8
lived through the worst battles have
civil war only to diet age 38 from

323
00:24:19,9 --> 00:24:20,70
yellow fever

324
00:24:20,70 --> 00:24:24,200
a pest not a bullet well besides the
mosquitoes

325
00:24:24,200 --> 00:24:27,480
in summer there is also a kind of insect
but never

326
00:24:27,480 --> 00:24:30,680
seems tired right that is the fly

327
00:24:30,680 --> 00:24:34,240
before I go on talking I must mention

328
00:24:34,240 --> 00:24:38,20
African fly called the tsetse fly which
feed on blood.

329
00:24:38,20 --> 00:24:43,600
and can cause serious diseases in the
people and animals that it by it besides

330
00:24:43,600 --> 00:24:45,000
it is still a Barra

331
00:24:45,000 --> 00:24:48,800
sleeping sickness which affects around
300,000 people

332
00:24:48,800 --> 00:24:52,909
every year in Africa and can be treated
only with toxic drugs

333
00:24:52,910 --> 00:24:57,850
but a hard to administer were still the
drug sometimes don't work

334
00:24:57,850 --> 00:25:00,909
other insects of course destroy food
crops

335
00:25:00,910 --> 00:25:06,110
in China for instance locusts continue
to be a danger to the harvest in some

336
00:25:06,110 --> 00:25:06,790
areas

337
00:25:06,790 --> 00:25:11,430
less important but still annoying Moxie
people's clothes

338
00:25:11,430 --> 00:25:15,300
and dust mites slowly destroy carpets
worse

339
00:25:15,300 --> 00:25:18,909
but still in the home termites all white
and eat word

340
00:25:18,910 --> 00:25:21,950
the would have your house if they are
not stopped

341
00:25:21,950 --> 00:25:26,650
they can eventually destroy the whole
building usually they seriously damaged

342
00:25:26,650 --> 00:25:29,260
a building before anyone even notices
them

343
00:25:29,260 --> 00:25:36,260
so as we all know insects can be a real
trouble

344
00:25:37,140 --> 00:25:41,919
so what to do you can go ahead and start
killing harmful insects

345
00:25:41,919 --> 00:25:45,860
in the early decades after the communist
revolution in China

346
00:25:45,860 --> 00:25:49,779
chairman mao encouraged the people to
swat every fight they could see

347
00:25:49,779 --> 00:25:52,929
slogans on the walls and buildings
called them

348
00:25:52,929 --> 00:25:57,500
little capitalist butterfly is
reproduced too quickly for this to be a

349
00:25:57,500 --> 00:25:58,890
long term solution

350
00:25:58,890 --> 00:26:04,39
for some decades in the West to kill
insects with chemical seemed a good

351
00:26:04,39 --> 00:26:04,760
remedy

352
00:26:04,760 --> 00:26:07,960
unfortunately chemicals can only be used

353
00:26:07,960 --> 00:26:12,649
in a limited area for a limited time
it's a small scale solution

354
00:26:12,649 --> 00:26:16,418
the insects come back were still

355
00:26:16,419 --> 00:26:21,490
some of the poisons use like DDT were
found harmful to the environment

356
00:26:21,490 --> 00:26:25,149
many kinds of wildlife like hawks were
harmed

357
00:26:25,149 --> 00:26:28,399
and people in chemical using rural areas

358
00:26:28,399 --> 00:26:31,500
have one of the highest rates of liver
cancer in the world

359
00:26:31,500 --> 00:26:35,110
it's no secret the chemicals remain
harmful to humans

360
00:26:35,110 --> 00:26:38,168
Michael species

361
00:26:38,169 --> 00:26:41,950
infected app to their changing
environment such an amazing rate

362
00:26:41,950 --> 00:26:45,289
when a new chemical is introduced to the
habitat

363
00:26:45,289 --> 00:26:49,629
the insects that survive a generally the
ones with some way of resisting the

364
00:26:49,630 --> 00:26:50,690
harmful effects

365
00:26:50,690 --> 00:26:54,929
they then breed with the other survivors
and just like that

366
00:26:54,929 --> 00:26:58,909
insects become resistant to most poison
in a few generations

367
00:26:58,909 --> 00:27:03,539
and infect generation remember is a
couple of months at most

368
00:27:03,539 --> 00:27:06,590
so a game we have to ask

369
00:27:06,590 --> 00:27:10,689
what to do well there are biological
solutions

370
00:27:10,690 --> 00:27:15,679
some of these are pretty simple one is
destroying the infect habitat

371
00:27:15,679 --> 00:27:21,360
you take away the home of food cleaning
your kitchen is the best way to prevent

372
00:27:21,360 --> 00:27:27,600
roaches no garbage no food getting rid
of marshes and swamps eliminates

373
00:27:27,600 --> 00:27:28,500
mosquitoes

374
00:27:28,500 --> 00:27:33,000
other solutions might include bringing
in dragonflies all backed

375
00:27:33,000 --> 00:27:38,320
in areas where mosquitoes are many this
is a cheaper alternative to chemicals

376
00:27:38,320 --> 00:27:44,340
biological methods like this also bring
no extra pollution to the environment

377
00:27:44,340 --> 00:27:47,80
but you have to be careful

378
00:27:47,80 --> 00:27:50,360
if you change the environment too much
you might be hurting

379
00:27:50,360 --> 00:27:55,418
other forms of life accidentally one
recent method of controlling insect

380
00:27:55,419 --> 00:27:56,360
populations

381
00:27:56,360 --> 00:28:00,449
involved interrupting their breeding
cycle what does that mean

382
00:28:00,450 --> 00:28:06,279
it means birth control for bugs insects
are provided with food

383
00:28:06,279 --> 00:28:10,830
that makes them unable to reproduce
since they can't have babies

384
00:28:10,830 --> 00:28:16,269
the population disappears or nearly so
and since no younger boy on

385
00:28:16,269 --> 00:28:20,760
resistance is not a problem with no
young insects developing increased

386
00:28:20,760 --> 00:28:21,559
resistance

387
00:28:21,559 --> 00:28:25,90
interrupt the life cycle eliminate the
bug

388
00:28:25,90 --> 00:28:29,240
it's clear that we must have an
understanding of the life cycle of the

389
00:28:29,240 --> 00:28:29,929
insect

390
00:28:29,929 --> 00:28:34,470
at least that's the plan will go into
more detail

391
00:28:34,470 --> 00:28:39,100
as the cost goes along now I will stop
here to see whether you have any

392
00:28:39,100 --> 00:28:42,360
questions or not

393
00:28:42,360 --> 00:28:49,360
that is the end of Section 4 you now
have hoffa minutes to check your answers

394
00:29:17,700 --> 00:29:19,730
that is the end of the listening test

395
00:29:19,730 --> 00:29:25,60
Ste in the aisles test you will now have
10 minutes to transfer your answers to

396
00:29:25,60 --> 00:29:25,919
