Humans have exploited the earth to such an extent, that from now onwards even if the average global temperature increases slightly, its effects are going to be worst.
Effect of global warming is almost similar to the rubber band that has lost almost its elastic property & even a small pull from now will break it.
There is an average increement of around 2 degree centigrade of average global temperature. As the human exploitation is going on a rapid rate, the average temperature might increase to even 4 degree centigrade very soon.
This in turn will increase the amount of carboin dioxide in the atmosphere. Increase in concentration of carbon dioxide will lead to global warming & the chain of environmental problems continues.
The humans are not aware that they are also being affected indirectly by there activities.
1. Due to excess of pollution the average human life span han gone down considerable. He is dieing very quickly when compared to the previous generations.
2. Due to their activities lands get submerged under the oceans which again affect them.
So nothing is late, just come together & help to save our earth & natural resources.
