World earth day, 22 april of each year, aims to raise awareness of environmental issues and to promote environmental protection actions at the global level. Launched in 1970 for the first time, by united states environmentalist gaston nelson, the day was designed to call for action to prevent growing environmental problems。
Since then, world earth day has become a global environmental event in which millions of people have participated and worked together to protect the planet's homeland. Each year, world earth day events have a specific theme, such as climate change, plastic pollution and forest conservation, aimed at drawing attention to current environmental issues。
World earth day events took a variety of forms, including seminars on various environmental topics, awareness-raising campaigns, clean-up initiatives, afforestation, energy-saving mitigation, etc., and interesting interactions, such as bicycle activities。
In addition to promoting environmental action, world earth day had had a profound impact on the global environmental agenda. In 1972, for example, the first environmental protection congress of the world was held in stockholm, sweden, under the auspices of world earth day. In addition, world earth day has encouraged businesses and all sectors of society to take additional environmental actions to protect the earth's ecosystems and preserve the harmonious development of humankind and nature。
