Importance of World Earth Day (WED)

Natural disasters are growing increasingly dangerous to humanity, owing to an increase in population and global warming, leading to a change in climate and an increase in sea levels. It is more likely that in the future, mankind will be evident of numerous disasters every year that will kill thousands of people.

In 2022, many significant green policy proposals were adopted by governments all over the world. However, only a few are implementing measures to achieve Greenhouse gas (GHG) neutrality by 2050. According to the recent Intergovernmental Panel on Climate Change report, if additional immediate steps are not taken to reduce greenhouse gas emissions, the earth will experience temperatures that are 3.2°C higher than pre-industrial levels, which would be disastrous for the human life.

It's the responsibility of each individual to protect the earth from natural calamities and provide a better place to live and sustain. World Earth Day signifies the importance of drafting new policies by the local environmental authorities and implementing action on existing environmental issues. In addition, WED educates the public about factors that affect the ecosystem and ways to protect earth’s flora and fauna.

History of World Earth Day (WED)

The first Earth Day was observed on April 22, 1970, and carried out by a senator, Gaylord Nelson from Wisconsin, along with a young activist Denis Hayes. He was motivated to initiate the event when he witnessed the harm of the oil spill incident in 1969 and realized the need for an awareness day to enlighten the people about the importance of environmental protection.

In 1990, Earth Day was globally recognized as 20 crore people from 141 nations joined in the forces to promote recycling around the globe, laying the groundwork for the 1992 United Nations Conference on Environment and Development, Brazil (Rio de Janeiro).

In 2010, EARTHDAY.ORG made Earth Day a crucial moment for people all over the world to take action for the environment. Lakhs of people from 193 countries have joined the environmental movement led by EARTHDAY.ORG. The organization has engaged more than 100 crore people annually in an Earth Day event, making it a pivotal event in the movement toward global environmental conservation.
