It is said that fossil fuels, particularly oil & gas, comsuption is the main cause of carbon dioxide production that leads to global warming in the last 40 years or so....

If these fuels were not blamed, could any research on cleaner (greener) energies had been easily justified, being so costly? Does anyone have the idea of how much just exponential population increase impacts global temperature? It is clear that the northern hemisphere is the more affected one by this actual temperature increase. Should we start thinking of controlling expansion of human beings on Earth for the sake of the planet (pollution & contamination reduction) and our own survival? Just out loud thinking!!!!
