The United Nations Environment Program (UNEP) has been promoting the World Environment Day theme every year since 1987.
The theme of the 2020 World Environment Day is 'Biodiversity', including climate change, environmental pollution, habitat destruction, etc.
It is time for human attitudes to change for endangered species due to global environmental problems.
Man cannot live without nature and the nature is sending us a message.
Please lower the Earth's temperature today, which is getting hotter through low-carbon life!
