World Environment Day is celebrated every year on 5 June in more than 100 countries. The theme for 2009 is climate change and the broader consequences of environmental change, and what societies can do in response.
Combating climate change and preserving ecosystems services that underpin our economies is an issue for everyone. Every individual's efforts, no matter how small, can contribute to the sustainable development of our economies and communities around the world.
On this day, individuals, non-governmental organizations, community and youth groups, business, industry and the media organize activities to renew their commitments to protect and develop the environment. They organize activities such as clean-up campaigns, tree planting, colourful street rallies, green concerts, essay and photo competitions in schools, and recycling efforts.
