Today we are celebrating ‘World Environment Day’. In 1973, United Nations Environment Programme (UNEP) marked June 5 as the 'World Environment Day' as a means to bring awareness among people to save the environment. Activists and organizations the world over are celebrating this day by organizing various programmes to create awareness on global environmental concerns so that people would be encouraged to take positive actions in their day-to-day life to reduce the degradation of environment. The UNEP’s theme for’ World Environment Day 2012’ is ‘Green Economy’ and the host country for the celebration is the Federative Republic of Brazil. In Kathmandu, Hotel Annapurna organized a cycle rally with the theme “Cycle-to-Work: Burn Calories, Not Oil.”
