Trees for the Earth
The International Mother Earth Day is observed every year on April 22 to raise awareness among humans that they have a collective responsibility to promote harmony with nature and to balance the economic, social and environmental needs of present and future generations. The 2016 theme is ‘Trees for the Earth’, which signifies that trees are crucial for combating climate change as they absorb harmful levels of Carbon dioxide (CO2) from the atmosphere.
