GLOBAL WARMING

The biggest problem

• Global warming is cousing a change the world’s climate. People produce a lot of greenhouse gases driving their cars and heating up their houses. That is WHY we can observe the increasing of the average temperature on the Earth.

• Next problem which is very important to the global warming process is deforestation. People need new teritories and they cut a lot of trees in the rainforest.

• An increaseing global temperature will couse seas and oceans levels to rise and probably change the climate on the Earth.

• For example, we will observe the expansion of subtropical deserts, melting glaciers and changing weather conditions.
