First marked by the United Nations 46 years ago, Mother Earth Day 2016 will look forward from the December 2015 Treaty of Paris, where world leaders finally passed a Treaty on Climate Change.

Preventing disease through healthy environments
An estimated 12.6 million people died as a result of living or working in an unhealthy environment in 2012 – nearly 1 in 4 of total global deaths. Environmental risk factors such as pollution, chemical exposures, climate change, and radiation contribute to more than 100 diseases worldwide. As the world celebrates Earth Day 22 April, people look at actions to reduce environment-related diseases by improving the environments where we live and work.
"Today, on Mother Earth Day, I ask each one of us to be mindful of the impacts our choices have on this planet, and what those impacts will mean for future generations."
UN Secretary-General Ban Ki-moon
