Summary
Since 1974, World Environment Day has been celebrated every year on 5 June: engaging governments, businesses, celebrities and citizens to focus their efforts on a pressing environmental issue.

World Environment Day, on June 5th, is celebrated to honour and recognise the significance of nature, environment and ecology that sustain all life forms around us.

World Environment Day (WED) is celebrated on June 5th every year to encourage environmental protection from environmental risks by encouraging awareness and actions for the protection of the environment. It was first held in 1974 by the United Nation, since then, it has been an important campaign to fight against emerging environmental risks from the human population, marine pollution, and most importantly, the increasing global warming, to sustainable consumption. 143 countries, from all over the world, actively participated in the campaign annually.

Every year, WED decides on a new theme and gains active involvement from the major NGOs, communities, governments, and celebrities worldwide to advocate the environment related issues.
