Anita Chitaya has a gift: she can help bring abundant food from dead soil, she can make men fight for gender equality, and maybe she can end child hunger in her village. Now, to save her home in Malawi from extreme weather, she faces her greatest challenge: persuading Americans that climate change is real. Traveling from Malawi to California to the White House, she meets climate sceptics and despairing farmers. Her journey takes her across all the divisions that shape the USA: from the rural-urban divide, to schisms of race, class and gender, and to the American exceptionalism that remains a part of the culture. It will take all her skill and experience to help Americans recognise, and free themselves from, a logic that is already destroying the Earth.

Huelva, Spain, an isolated region lost in time. The grass, the sand and the sky are the same that those foreigners saw in the spring of 1895, when they crossed the sea from a distant country to mark the unspoiled terrain and extract its wealth, when the tower was new, when people could climb to the top of the highest dune and imagine that the city of Tartessos was still there, in the distance, almost invisible in the morning brume.

This video includes excellent scenery and computer-generated videos that provide nice visual aid. These visual aides and the facts given by the narrator deliver on the National Geographic credibility you have come to expect. It includes wildlife in the Denali area, including two moose battling for a mate, as well as a brown bear cub taking out a caribou. The wildlife portion takes up about half of the video, about 25 minutes or so. The second half of this DVD shows a group of eight individuals who are climbing Mt. Mckinley. This gives an additional viewpoint of the Denali area for those who seek challenging ventures. The cons about this video are that I would have liked to see a longer wildlife portion, and it is not a very long video altogether (50 minutes), so the $18 price tag seems a bit much. If you are interested in Alaska, the arctic, national parks, mountain trekking, and wildlife, this is a good movie for you.
