The document discusses how pollution has led to environmental changes over time in several areas. Melting ice due to contamination has reduced polar bear populations and habitat. Deforestation and fires caused by humans have decreased vegetation in mountain regions. Increasing air and water pollution from vehicles and industry has worsened air quality, contributed to warmer weather, killed trees, and threatens to contaminate all water if pollution continues rising.

2. In the first picture we can see a polar bear
on a lot of ice whereas in the second
picture we can see a bear on a small
iceberg because the contamination melt
ago the ice and there are fewer bears

the mountains and now a days because of

sky, but in the picture above we see a
contaminated sky caused by smoke of the
cars

5.  In 1928 the weather was colder, but in 2004
the weather changed because the humans
pollute much

6.  In the first picture we can see green tree,
whereas in the other picture we see the dead
trees, because it doesn’t rain

7.  Regret: If we hadn't polluted now we will
have a better vegetation
 Hypothesis: If we would have not polluted
much there wouldn't be much vegetation
and animals dead
 Prediction: if we keep polluting much the
water will come a day when all the water
will be contaminated
