In this Yale Environment 360 video, we present the first of a two-part e360 series, "Wasted," on the vexing global problem of food waste. Filmmaker Karim Chrobog visits two cities - Washington, D.C., and Seoul, South Korea - to examine why so much food goes to waste and what can be done about it. Washington, and the U.S. as a whole, has taken only minor steps to reduce this enormous waste and its related human and environmental costs. By contrast, Seoul has adopted innovative programs to minimize the amount of food that ends up going to landfills to rot. 

An estimated 1.3 billion tons of food is wasted each year, totaling $750 billion in economic losses, according to a 2013 report from the United Nations that analyzed loss of food around the world.

Ringling Brothers and Barnum & Bailey is ending more than a century where elephant acts were a defining mark of the circus. It is a smart business and political move, one that reflects a deeper change in cultural preferences.

Starbucks has announced it will stop sourcing and manufacturing its Ethos Water in California due to the drought.

If the global business community is to thrive in the long term - and carry us to that flourishing future we are trying to imagine and help build - it needs to continue to scale up the ambition and influence of its efforts. That's much easier said than done, of course, though we are seeing a number of encouraging trends within the Sustainable Brands community that, while still nascent, are promising to deliver a lot of value for years to come. 

Worldwide levels of carbon dioxide - the gas scientists say is most responsible for global warming - reached a significant milestone for the month of March, the National Oceanic and Atmospheric Administration said Wednesday. The global monthly average for carbon dioxide hit 400.83 parts per million in March, the first time the average surpassed 400 ppm for an entire month since such measurements began in the late 1950s, NOAA said.

The United States and China contributed most to record mountains of electronic waste such as cellphones, hair dryers and fridges in 2014 and less than a sixth ended up recycled worldwide, a U.N. study said on Sunday. Overall, 41.8 million tonnes of "e-waste" - defined as any device with an electric cord or battery - were dumped around the globe in 2014 and only an estimated 6.5 million tonnes were taken for recycling, the United Nations University (UNU) said.

A few basic (and often profitable) changes in a factory's manufacturing process can go a long way in cutting down pollution.

The shareholder vote was extraordinarily lopsided, with about 98% of shareholders approving the resolution, which had the backing of BP's chairman, Carl-Henric Svanberg. The embrace of the climate change resolution is being called a watershed event in the history of climate-related shareholder resolutions, which investors large and small have been pursuing since 1999 to try to encourage oil, coal and gas companies to inform shareholders of their climate change-related risks and shift their investments into renewable sources of energy.
