Mali's Magic Weed

Normally we think of weeds as those pesky, unwanted plants stealing the nutrients from our carefully tended vegetables or roses. But what if a weed could help stop global warming and alleviate poverty?

This magic weed is called jatropha. It grows around the world, in Latin America, Asia, Africa. Farmers in Mali, West Africa have discovered that cultivating this weed may prove profitable. Why? It is used as biofuel. Already, jatropha is used in Mali to power generators for electricity. Oil companies like BP have begun investing millions into growing it.

Jatropha grows in a variety of climates, and does well in Mali's dry, Saharan farmland. It can grow beside food crops and its yield is much higher than that of other biofuel crops, like corn. Additionally, it helps prevent erosion and does not endanger other habitats the way a crop like palm oil, which takes land away from the rainforest, does.

But, will jatropha prove to be such a lucrative crop that farmers sacrifice land on which they currently grow food crops in its favor, thus leading to food shortages in Mali? And will it actually increase poverty by concentrating power in the hands of a few growers?
