Bollywood actor-activist Rahul Bose has slammed developed countries for preaching to developing nations to reduce "the use of energy sources" in order to cut down on "greenhouse gases (GHG) and carbon emissions" without practising the same.

"Developed nations have enjoyed unbridled use of the fossil fuels to reach a level of prosperity that is ten times our level. Now, just when we are attaining the first levels of prosperity you want us to reduce our energy consumption?" Rahul posted on blogu00a0this Sunday.
