The first World Environment Day was celebrated in 1974 on June 5 and has been celebrated every year since in more than 100 countries.
The United Nations purposed the day to provide an opportunity to broaden the “basis for an enlightened opinion and responsible conduct by individuals, enterprises, and communities in preserving and enhancing the environment,”
The theme for 2019 ‘Beat Air Pollution’ is a call to action for combating the global crisis and has been chosen by this year’s host, China.
The topic invites people to consider how they can change their everyday lives to reduce the amount of air pollution and curb its contribution to global warming and its effects on health.
The UN says that understanding the different types of pollution, and how it affects our health and environment, will help people take steps towards improving the air around them.
UN is concerned about factors like household air pollution which is caused by indoor burning of fossil fuels, wood and other biomass-based fuels.
This leads to around 3.8 million premature deaths, mostly in developing countries.
Industrial and transport pollution have been linked to thousands of premature deaths worldwide annually.
Around 24 percent of greenhouse gas emission worldwide come from agriculture, forestry and other land-use.
