With deep azure skies, bountiful sunshine, and a crisp but mild breeze today, spring is by far my favorite season in Washington. Today marks the 40th year since the advent of Earth Day, an occasion to create awareness and appreciation of the Earth’s environment that we all share in and enjoy. The event is now celebrated around the world as resources are increasingly stretched and environmental issues becoming more pertinent in our everyday lives.
I wanted to give an overview of some Earth Day related events happening in South Asia to mark the occasion.
National Saplings in Kabul : Green coverage has been reduced from 14 million hectares to 1 million hectare in Afghanistan.
"One tree for myself, one for Afghanistan.” the Greening of Afghanistan Campaign, is a five year annual campaign to restore green zones of Afghanistan and encourage citizens for saving environment. Every single Afghan citizen participates and plants two trees. One for themselves and one for Afghanistan.
A single tree produces approximately 260 pounds of oxygen per year. That means two mature trees can supply enough oxygen annually to support a family of four.
