What will happen to the Earth if the air becomes polluted?

Let’s think about what would happen to the Earth if it were surrounded by a polluted atmosphere. One worry is destruction of the Earth’s environments due to air pollution.

Another problem people often talk about is global warming. When factories and other places burn things, lots of carbon dioxide and other gases are made. Because carbon dioxide traps heat, temperatures will go up. Higher temperatures cause abnormal weather and other problems.

Polluting substances are also the cause of acid rain. Polluting substances emitted by factories and cars are absorbed by clouds, making rain more acidic. Acid rain creates many kinds of damage, including killing forests and crops.

The destruction of the ozone layer is another huge problem. The ozone layer is what protects us from harmful ultraviolet rays from the sun. Fluorinated gases used in aerosols and other products eat away at the ozone layer. If the ozone layer is destroyed, ultraviolet rays will reach the Earth and damage living things.
