Earth Day to be observed on April 22

Earth Day will be celebrated on April 22 all over the world including Pakistan. Every year, the Earth day marks the anniversary of what many consider the birth of the modern environmental movement in 1970.
This year theme is 'Mobilise the Earth', which recognises that on Earth Day 2012 people of all nationalities and backgrounds will celebrate the planet and encourage its protection.
Together, they are united for a sustainable future and urge individuals, organisations and governments to do their part.
