Earth Hour (8 pm to 9 pm) may have gone unobserved in many parts of the State on Saturday, but not for Aaron Pereira, a first year BA student residing at Fontainhas in Panjim. Aaron was kept busy for most part of the day sending e-mails and contacting friends to make them aware of the important hour when lights would be switched off in an effort to raise awareness about global warming. The student and nature enthusiast said a few people in Panjim did keep a date with the crucial hour, which is being observed from last year and finds its genesis in Sydney, Australia, by the World Wildlife Fund (WWF). Citing the unexpected showers preceding Easter Sunday, Aaron said the sudden rainfall could be attributed to climate change. "It is high time we realise the importance of preserving our Earth for our future generations,' he mentioned. Aaron has formed WeCare - Goa, a youth environment organisation, to take up the issue of global warming in the State as he feels there's a need for creating awareness on the phenomenon. "WeCare - Goa has decided to hold various campaigns on global warming throughout the year by involving various sections of the society, right from children to the aged,' he observed. Aaron has urged like-minded people who have interest in such issues and who want to take an active part in protecting the Earth could contact WeCare - Goa at wecaregoa@gmail.com.
