Over 16 million people displaced in one country, millions displaced in another, due to deforestation on the banks of their rivers and almost all the lakes world over especially in developing world or in semitropical and tropical conditions and especially fragile ecosystem are gone. Europe suffered over 30 degree for weeks with erratic winter, Russia once know for its cold is burning with heat wave, almost millions of people are suffering world over. I dont know what is green house effect and how does it influence the global warming ( scientific debates on yes or no about this ) but I know if plants are not there human beings cant survive. Lay more emphasis on preventing deforestation , promote plantations on the hills river banks and people will live.
