The International Mother Earth Day is celebrated on 22 April, each year, to raise the awareness about the environmental issues and the need to protect the earth.

The idea of an Earth Day was initially envisaged by Gaylord Nelson, a US senator, who witnessed a massive oil spill off the coast of California in 1969. In 1970, over 20 million people celebrated the first Earth Day.

"Groups that had been fighting against oil spills, polluting factories and power plants, raw sewage, toxic dumps, pesticides, freeways, the loss of wilderness, and the extinction of wildlife suddenly realised they shared common values," stated in the official website of Earth Day.

The significance of the day grew over the years and the Earth Day became a global celebration by the beginning of the 90's.

In 1990, millions of people joined in the Earth Day celebrations with activities spanning 141 countries across the globe.

The 30th anniversary of the event was held in 2000 with a focus on clean energy while the 40th anniversary in 2010 focused on the need to plant more trees. The initiative was to plant 100,000 trees in a single year.

The theme of Earth Day 2012 is "one billion acts of green" which is aimed at encouraging individual involvement in creating awareness about the environment.

According to the organisers, the theme focuses on creating awareness about the simple every day environment friendly acts such as switching off lightbulbs or reducing car journeys that can have a huge positive impact on the environment.

Earth Day 2012 is observed in 192 countries, according to the oraganisers.
