Pre-monsoon drizzles have begun and Mumbai's schools and colleges are gearing up for admissions. Corporates, on the other hand, are ready to kick-start their tree plantations and awareness campaigns, on the occasion of World Environment Day (WED). To raise awareness about environmental issues and to encourage action to protect nature, the United Nations Environment Programme (UNEP) celebrates World Environment Day on June 5. Every year, UNEP picks a host country and a theme for the annual celebration. In 2011, India hosted WED with the theme, Forests: Nature at your Service.

Angola hosts this year's WED, rallying around the theme of illegal trade in wildlife and related crimes which undermine economies and security, especially in developing countries. Across the globe, various NGOs, corporates and individuals put together innovative events to celebrate World Environment Day through film festivals, art and craft activities, sale of eco-friendly products and a string of competitions, exhibitions and rallies. The WED slogan poignantly points out 'Only One Earth', but the real question is — Is one day in a year sufficient to undo hundreds of years of damage to the Earth?
