Global warming is on the rise as more forests are cut down and more vehicles are on the rise. When the Co2 capacity is increased in the air, the global warming is increased.
The more forests there are the better. As we all know, Sahara is the world largest desert. So we need to exploit this land for plantation. The main problem is the lack of water.
However the sahara desert is near to the sea. So the sea water can be used as a source for water.
A new mechanism needed to be designed to desalinate the sea water. Solar energy should be used for this.
