Q.Which day is observed as 'World Environment Day'?

Important Environmental Days

Environmental problems — pollution, deforestation, climate change, loss of wildlife — are too large for any one person to fix alone, so societies use awareness days to focus public attention, education and collective action. These observances are simple in idea but powerful in practice: a fixed date each year that reminds everyone to think and act on a specific environmental theme.

Why we mark environmental days

The reasoning is behavioural. People act on what they are reminded of. By dedicating a day to an issue, governments, schools, NGOs and citizens run campaigns, plant trees, clean up areas, and spread information — building the public awareness needed to support conservation policies and change everyday habits.
