Importance of world Environment day

World Environment Day

The key goal of declaring June 5 as World Environment Day is to raise awareness about protecting our environment. The day is dedicated to raising awareness of environmental issues such as global warming, marine pollution, human overpopulation, wildlife conservation, and sustainable consumption. Nature provides us with the foods we consume, the air we breathe, the water we drink, and the atmosphere that allows us to live on this planet. For example, marine plants generate more than half of the oxygen in our atmosphere each year. A mature tree cleans our air by consuming 22 kilos of carbon dioxide and emitting oxygen in return. Despite all of nature’s advantages, we continue to deteriorate it. World environment day is renowned as the day for environmental action.
