People celebrate World Environment Day (WED) in many different ways all over the world: planting trees, cleaning up local beaches, organising meetings, joining online protests. Each year the United Nations Environment Programme (UNEP) chooses a particular issue to focus on. One year it might be forests, another year it might be wildlife. And each year there is a new host; a city which is the centre point for all the celebrations.

How it first started
The United Nations (UN) named 5 June as international World Environment Day at the Stockholm Conference on the Human Environment in 1972. The idea was to draw attention to the many problems that are facing our environment. They wanted to include as many people, organisations and governments, both local and national, as possible. They wanted to show that positive change is possible when people work together to fight for a common cause.
