Every year on 22 April, an environmental holiday Earth Day is celebrated. It was established by the United Nations and reminds us of the need to be conscious of nature and its resources.

Anyone can take part in Earth Day celebrations - for example, by clearing a forest or park area of garbage or planting a tree.

This day features various environmental events, including Earth Hour, when participants turn off lights and electrical appliances for one hour; A car-free day, when motorists turn into pedestrians or cyclists; March of Parks to support protected areas.
