What are our forests really made of? From the air, ecologist Greg Asner uses a spectrometer and high-powered lasers to map nature in meticulous kaleidoscopic 3D detail -- what he calls "a very high-tech accounting system" of carbon. In...

The technology we use to keep cool is heating the world in a vicious feedback cycle, so we need to improve it and use it less.

During the hot summer months, watching an outdoor sports match or concert can be tantamount to baking uncomfortably in the sun -- but it doesn't have to be. At the TEDxSummit in Doha, physicist Wolfgang Kessling reveals sustainable...

Nitrogen makes up 78% of the air, however neither plants nor animals can take nitrogen directly from the air because nitrogen is so unreactive. The nitrogen cycles shows the movement of nitrogen through the environment. Nitrogen is...

An introduction to the chapter "Adapting and Living Together" within the Ecology and Environment topic of school Biology. Where do you live? On a country farm? In a big city? Up in the mountains, or right by the ocean? The place where...

As populations have grown, farming practices have become more intensified to maximise crop yields and ensure we can feed the ever growing population. Fertilisers and pesticides are used on crops, and animals may be kept inside in more...

Through photosynthesis, plants take in carbon dioxide from the air and split it and use it (and water) to make carbohydrates. So surely plants can help us reduce carbon dioxide in the air? Possibly... But equally, the carbon in plants is...
