The NDVI (Normalized Digital Vegetation Index) is on of the primary methods for detecting healthy vegetation using satellite imagery. This also serves as a useful way to distinguish between distinct ecological and agricultural regions and the temporal patterns of planting seasons.

This video is a fascinating portal into global food systems and how globalization is impacting local foods. He traveled around the world to see what families eat in a given week, and how much all the food cost and where it can from. Many wealthy countries exhibit poor nutritional habits (eating food high in fat, sugar and salt) while some in poorer people have a very balanced diet. This leads him to describe the 'Nutritional Transition.' Warning before showing in class: there are brief instances of non-sexualized nudity in the video. Via Seth Dixon Delete the scoop?

Hungary has taken a stand against biotech giant Monsanto and genetic modification by destroying 1000 acres of maize grown with genetically modified seeds.
Peru and Hungary have both banned GMOs. What are the reasons that many are critical of GMOs? What should the government's role be in agriculture and food systems? Are bio-tech companies too strong? Via Seth Dixon

With Monsanto having such a large political power, this is very interesting tat Hungary took a stand.

This article is about countries that are taking a stand against the company Monsanto. Many people in those countries are critical against the use of GMOs because they're not sure about how the genetic engineering will affect the crops. Already GMOs have had negative effects. The use of GMOs reduces the variety between the seeds. Not only that but the farmers are no longer getting the money the deserve for their hard work and they are not allowed to save their seeds. The government should have little control over the agriculture and what they decide to plant. They should take more precautions against the GMOs and they should make sure that the food system companies in charge of checking the safety food should not have a connection to the very food companies they are supposed to be condemning. Bio-tech companies are getting too strong because they're gaining too much control of the fields due to the patents they hold on their GMOs. This is dangerous because they could end up having a monopoly on the franchise and when they due if something happens to their crops it will happen to all the crops. It will be, for lack of a better word, very bad.
