Indian environmentalists T. Srinivasa Rao and R. Gnanasekaran from, who are on their seventh globe-trotting expedition to raise awareness on global warming, have said that they believe in the importance of giving back and urged world to opt for green solutions.

"One truth is that the more you give, the more you get in return. And the more you give to the earth, the more the earth will give back to you," The Star quoted Srinivasa, as saying.

The duo is currently in Malaysia and received 1,000 dollars (RM 3,200) from Selangor state exco member Ronnie Liu, to work with communities and neighbourhoods to help protect Mother Earth.

Gnanasekaran said being green was not just about contributing money but also one's time and talents.

"Malaysia is a beautiful nation blessed with abundance of sunlight and this natural resource can be turned into solar energy. Paying utility bills is absolutely unnecessary. Making the solar panels will be cost-effective if all houses are fitted with it," he added.

He further stated that the use of fossil fuel pollutes the air, which leads to global warming and ultimately depletes non-renewable resources. He urged developed countries like the United States to support developing nations with financial grants to develop renewable-energy projects to improve the environment.

Srinivasa and Gnanasekaran, both electrical engineers, started their global awareness campaign in 1986 with their first expedition on bicycle covering 68,000km.

The duo would be heading to Argentina and travel through South America before arriving in Mexico for the United Nations Framework Convention on Climate Change in December. (ANI)
