A new Living Planet Index report from the London Zoological Society and the World Wildlife Foundation says the world’s populations of wild animals are an average of half the size they were in 1970. The index tracked the populations of more than 10,000 representative populations of species from 1970 to 2010 and showed a bigger decline than previously thought (prior studies estimated that populations had declined by 30 percent). The report sites human consumption—and the resulting habitat loss—as the main reason for the decline. According to the report, there are only 3,000 tigers left in the wild today, as opposed to 100,000 a century ago. And Elephant populations in West Africa are living on about 7 percent of their historic land due to deforestation. You can check out the full report here for more information and ways to get involved to slow the decline ...

It also contains well over 200 species of fish that occur nowhere else in the world.

For generations, communities along the shoreline have thrived on the lake’s clean water, vibrant fishery and accessible boat transportation. Read More

Coke is sending tens of thousands of the caps to several Asian countries later this year ... Discuss

While documentaries like Food, Inc., Forks Over Knives and King Corn captivate viewers with investigations into the ethics of agribusiness, a new trend is taking hold with diners: holistic food. The rise of socially conscious consumers—aware of both the health and ethical consequences of what they eat—has fueled a food revolution that has inspired restaurants, grocers and farmers to rethink the business of what we eat.
