There are 1100000...trees in the world. Trees produce Oxygen and consume CO2 , a very bad gas. Every year, the people cut a lot of trees. In the end we won't have oxygen to breathe.
So, what's the problem?
The trees need the light of the sun, CO2 and minerals. With this, they create glucose, H2O and Oxygen. CO2 increments the world's temperature. Well, don't will have trees, we will don't have Oxygen.
How can you help?
- consume less paper, for example.
