It's only day three of negotiations at the UN Climate Change Conference in Copenhagen, and the climate change roller coaster is quickly gaining momentum, with new urgency to release a draft climate agreement before the weekend. On Monday, the U.S. took strides towards regulating emissions when the Environmental Protection Agency announced the dangers of greenhouse gases on human health -- an important step towards setting tougher national emissions standards. But shortly thereafter, the U.S. and others took a hit with the leak of the "Danish Text", a controversial proposal by several parties, such as Denmark, the U.S., and the U.K., that attempts to give regulatory control to rich nations instead of the UN in setting international emissions standards, and drastically reduces CO2 targets for rich countries. This has no doubt infuriated many developing countries who are seeking to hold these very countries accountable for the emissions they produce.

Africa, for example, is demanding reparations for the devastating impact of heavy-emitting countries on their continent's natural resources and environment. Learn more about this from the latest episode of Link's Global Pulse, Africa: Cash for Climate Change?, and then have your say on whether or not you agree. Also, we hear so much about the melting glaciers of the Arctic, but we rarely hear about the lives of the people there, and how they are being impacted by rising temperatures and changes to the environment. This week, Link TV is airing explore: Arctic - Change at the Top of the World for a look at one of the most fragile and remote parts of the world.

One video from the remote Republic of Kiribati, while dated by its title, holds particular relevance due to the emotional presence of tiny island nations making their plea during negotiations this week.

The industrialization of the U.S. food system is multiplying rates of obesity and preventable illness. Our planet is suffering as well: the massive amounts of oil, coal and natural gas needed to produce, distribute and refrigerate our food is putting further strain on the planet's limited resources. I recently heard that a grocery chain that touts themselves as "green" flies their salmon to Japan to be filleted, then flies it back to the U.S. for sale in their stores! Michael Pollan, author of The Omnivore's Dilemma and In Defense of Food, says: "When we eat from the modern industrial food system," Pollan says, "we are eating fossil fuel and spewing greenhouse gas."

Though this situation seems abysmal, Pollan offers real alternatives to our current system; alternatives and solutions for a healthier, safer and more environmentally-friendly food supply.
