How does the Amazon rain forest cope with drought? The Amazon rain forest isn't necessarily a place that many would associate with a drought, yet prolonged dry spells are projected to become more prevalent and severe because of climate change. The question at hand is how these droughts are going to affect

While it's known that farmers' decisions to add nutrients to their fields affects greenh
Dry inland waters are underrated players in climate change Climate change causes an increase in the number of freshwaters that run dry, at least temporarily. Around 90,000 square kilometres of water surface have already vanished in the last 30 years. This trend is not only a threat to drinking water reserves and
Using bacteria to create a water filter that kills bacteria Engineers have created a bacteria-filtering membrane using graphene oxide and bacterial nanocellulose. It's highly efficient, long-lasting and environmentally friendly -- and could provide clean water for those in need.
