The ozone layer is now getting thinner and thinner due to the harmful human activities that we do everyday. Humans harm the environment which will lead to deforestation and pollution.

Deforestation will lead to a state where there will be a loss of living things , soil erosion , global warming .

Loss of living things
Besides killing trees , deforestation has caused may living things to lose their shelter and food source . This is because trees are the habitats of many animals and plants . Trees also provide food to many animals . Without shelter and food , animals and plants will die .

The bad impact of cutting down trees
A lot of people wonder what is so bad of cutting down trees as they can grow back again .Althoughs tress can be grown back again , it may take a very long time for a forest to recover.This is because other living things and non-living things are also destroyed when a forest is cleared.

Soil erosion
Soil erosion is the removal of soil by wind and rain .

There will be a cause of pollution because people litters their rubbish everywhere and everyday , people smokes and the air released by the factories are harmful and poisonous that can cause eye irritation and damage our respiratory system which will cause lung cancer which is bad for our health . Burning of forest also can cause haze . Haze affects our health because it can cause us to have eye irritation and breathing difficulties .
Those air released by the factories also can cause acid rains . This will also lead to loss of marine lives and also it will contaminate our water supplies . Acid rain reacts with stones and cause stones to corrode and will also react with other substances .They will spoil buildings and outdoor structures. Man-made chemicals / natural resources can lead to both land and water pollution too !
