Earth Day, the largest international campaign focused on environmental protection, is observed annually on 22nd April. It was first celebrated in 1970 in the U.S. Nowadays, the campaign is organised in 192 countries with the assistance of more than 22,000 partner organisations, and more than one billion people from around the world are involved in the activities. The Czech Republic has been celebrating Earth Day for more than 20 years.
This year too, Healthy Cities, Towns and Regions were part of the Earth Day campaign organising awareness-raising actions focused on learning about nature and environmental protection but also on Eco-fairs, spring cleaning or entertaining events for children focused on environmental education. Healthy Cities and Regions also prepared varied complementary activities for the public. At the events, participants could buy fair-trade products as well as typical regional products. The activities of Earth Day celebrations also involved a number of professional partners, including zoos and organised nature conservationists.
Twenty-nine Healthy Cities and Regions joined the celebrations of Earth Day 2017.
