Reducing Food Waste
We have talked about food waste before. It is a big problem in this country: some 31% of our food supply is wasted, more than 130 billion pounds a year. Food waste makes up 21% of solid waste in municipal landfills, which means that it accounts for the bulk of landfill methane emissions. Methane is more than 20 times more effective as a greenhouse gas than carbon dioxide, and landfills are a major source of it.
Killer Air
Globally, air pollution kills 3.3 million people per year. And this number could double to 6.6 million people by 2050 if little is done to decrease the dangerous levels of tiny particles, toxins, and ozone in the air.
Implications of a Thousand
The first Earth Wise broadcast was on January 2, 2012. Today marks the 1000th story we have presented to you, which is cause for celebration.
Coal Subsidies
Coal is the most important energy source for the Chinese economy and in a number of other places around the world. It is still the largest source of electricity in the US. It is also one of the main reasons that greenhouse gas emissions continue to increase despite worldwide technological progress and the expansion of renewable energy. New coal plants are still planned in many places and such plants will emit carbon dioxide for decades.
Reducing Methane In The Atmosphere
Methane is the main component of natural gas. It is also a potent greenhouse gas, having 25 times the heat trapping ability of carbon dioxide.
Mercury And Selenium Pollution In The Grand Canyon
The Grand Canyon Reach of the Colorado River is breathtaking and remote. For hundreds of miles, the rugged landscape renders the river virtually inaccessible to people. Those intrepid enough to explore the area are treated to red rocks, blue skies, and meandering waters.

Outsourcing Our Emissions
The average American is responsible for one of the largest carbon footprints in the world. Some 37% of our carbon emissions is associated with electricity generation; 33% stems from transportation – largely personal automobiles. The remaining 30% is attributed to industry, residential use, and agriculture.
