Why it’s so hard to cure HIV/AIDS – Janet Iwasa

View full lesson: http://ed.ted.com/lessons/why-it-s-so-hard-to-cure-hiv-aids-janet-iwasa↵↵In 2008, something incredible happened: a man was cured of HIV. In over 70 million HIV cases, this was a first, and, so far, a last, and we don’t yet understand exactly how he was cured. But if we can cure people of various diseases, like malaria and hepatitis C, why can’t we cure HIV? Janet Iwasa examines the specific traits of the HIV virus that make it so difficult to cure.↵↵Lesson by Janet Iwasa, animation by Javier Saldeña.

Where does your fruit come from and at what cost? | DW Documentary

Costa Rica is the world’s largest pineapple producer and Germany’s main supplier of the fruit. Cheap labor and pesticides mean low prices in Western Europe.
While organic pineapples are now being farmed on a larger scale to increasing demand, this likewise has negative consequences for Costa Rica’s ecosystem. Tropical fruits such as pineapples, bananas and kiwis have been available in West European supermarkets for years. But the innocent appearance of these popular products is deceptive. The fruits are cheap because costs are cut in the production countries – affecting wages and health factors. Costa Rica is the world’s largest pineapple producer, and is known both for its exemplary ecological approach and for sustainable tourism. It is in this very country, however, where workers on plantations complain about a lack of rights. Pineapples are grown and harvested here in vast monoculture plantations using huge amounts of pesticides. According to studies conducted by Costa Rica’s national university, the country is not just a major tropical fruit exporter but also the world’s biggest per-hectare user of pesticides. Plantation workers have as a result been reporting rashes and headaches. At the heart of pineapple farming, to the northeast of the capital of San Jose, trucks regularly have to supply villages with clean drinking water because the groundwater has been contaminated with bromacil – a weed killer banned in the EU. In the north of the country huge pineapple plantations are threatening the livelihoods of traditional small farmers, while conventional banana plantations continue to grow across the southwest. Many supermarkets in Europe have recognized that they can make money with sustainability. Almost all the major chains have signed up to ecological quality seals that stand for responsible growing methods with low pesticide use. The example of Costa Rica, however, shows that such promises aren’t always strictly kept. Although there are farmers who have set up their own businesses with the new growing methods, and although the organic sector in Costa Rica is constantly growing, even organic bananas and pineapples require large areas of land for farming. The result is monocultures with consequences for the ecosystem.
