Deforestation

Did you know that deforestation is the permanent destruction of indigenous forests and woodlands?
Of course doing this will have its consequences.
It is estimated that deforestation contributes one-third of all CO2 releases caused by people.
And we all know that CO2 is the major contributor to the greenhouse effect.
The effect of deforestation could also be a drier climate.
THE BEST PART IS THAT WE CAN HELP!
The website says that we can:
-use wood sparingly
-plant indigenous trees
Here comes the info about THE CARBON CYCLE.
Forests act as a major carbon store because carbon dioxide (CO2) is taken up from the atmosphere and used to produce the carbohydrates, fats, and proteins that make up the tree. When forests are cleared, and the trees are either burnt or rot, this carbon is released as CO2. This leads to an increase in the atmospheric CO2 concentration.
Here comes the info about THE WATER CYCLE.
Trees draw ground water up through their roots and release it into the atmosphere (transpiration). In Amazonia over half of all the water circulating through the region's ecosystem remains within the plants. With removal of part of the forest, the region cannot hold as much water. This causes a drier climate.
