00:00:00,000 --> 00:00:27,530
Good morning, I am Ivan and we are going to talk about people in the environment.

2
00:00:27,530 --> 00:00:37,530
Concretely, we are going to talk about pollution, desertification, deforestation and the endangered species.

3
00:00:37,530 --> 00:00:49,229
Pollution is the accumulation of rubies and harmful substances in the air, water and soil.

4
00:00:49,229 --> 00:00:57,590
Global warming is the increase of temperatures on the planet, produced by expulsion of gases

5
00:00:57,590 --> 00:01:11,510
from vehicles, air-tube systems, and the gases that some industries release into the atmosphere.

6
00:01:11,510 --> 00:01:20,510
The gases retain heat. All this is produced by what is known as the air pollution.

7
00:01:50,659 --> 00:01:57,659
Accumulation of rubies from human activity can contaminate the soil and is called soil pollution.

8
00:02:25,449 --> 00:02:26,449
Soils.

9
00:02:27,449 --> 00:02:28,449
Detergents.

10
00:02:28,449 --> 00:02:39,889
industrial waste and chemicals used in agriculture can contaminate bodies of water.

11
00:02:39,889 --> 00:02:42,889
This is called water pollution.

12
00:02:42,889 --> 00:03:07,680
Deforestation and desertification

13
00:03:07,680 --> 00:03:12,680
Deforestation refers to the disappearance of forests.

14
00:03:12,680 --> 00:03:22,680
It can happen through forest fires or because people cut down too many trees.

15
00:03:22,680 --> 00:03:30,680
Deforestation laves the soil unprotected against erosion.

16
00:03:30,680 --> 00:03:37,680
It also trains the animals that depend on trees.

17
00:03:37,680 --> 00:03:51,680
Desertification is the slow transformation of fertile land into a desert.

18
00:03:51,680 --> 00:03:58,680
It usually happens as a consequence of deforestation.

19
00:03:58,680 --> 00:04:05,680
Sowing with no vegetation can be easily eroded.

20
00:04:05,680 --> 00:04:13,680
This means that water and wind carry away the fertile layer of soil.

21
00:04:13,680 --> 00:04:24,680
The consequence of pollution, deforestation and desertification is the extinction of species.

22
00:04:24,680 --> 00:04:26,680
Endocrine species

23
00:04:26,680 --> 00:04:33,680
Endocrine species are living things at risk of becoming extinct.

24
00:04:33,680 --> 00:04:53,360
Extinction is the complete disappearance of a species from the earth. Pollution, deforestation and overexploitation are trees to many species of animals and plants.

25
00:04:53,360 --> 00:05:01,360
The extinction of a species causes serious consequences to the ecosystem.

26
00:05:01,360 --> 00:05:11,360
It affects all the other living things within that ecosystem.

27
00:05:11,360 --> 00:05:18,360
For example, if producers in an ecosystem become extinct,

28
00:05:18,360 --> 00:05:30,959
Consumers will not be able to obtain food. Without food, these consumers will also become extinct.
