Palm oil can mean steady, consistent income for farmers in the developing world, but it can also means environmental degradation and other abuses. As palm oil expands in Latin America, can it take a different course?
As the climate changes, biodiversity will become increasingly important. Biodiversity could be the keys to the species of rice that can survive wild swings in precipitation, or the type of yam that can grow in soil that has turned sandy. And the world's seed vaults may play a crucial role in that.
Meet the coywolf — a mixed-breed better able to kill deer. Thanks to human activity, native animals and plants are expected to hybridize more than ever. Is that a problem — or a solution?
Desalination — taking the salt out of seawater so humans can drink it — is becoming more important as the Earth warms and drinking water gets more scarce, but it's not a cheap or simple process. Here are some ways it might get more affordable and environmentally friendly.
For farmers and ranchers in the American West, the successful reintroduction of wolves and grizzly bears has presented a new challenge for keeping livestock safe. While guard dogs have protected thier flocks and herd from coyotes, grizzly bears and wolves require new, bigger, stronger dogs.
Solar power and natural gas seem like competitors in the race to create new power generating capacity. And that's true — to an extent. But they both may be crucial to helping meet future global energy needs — and reducing the risks of climate change.
Modern varieties of rice may produce high yields, but they can't withstand the tough conditions that are becoming more common as climate change affects farming. That's why Indian scientists are turning to older, indigenous grains to keep communities fed.
