A new approach to water desalination

From the Massachusetts Institute of Technology (MIT)

The availability of fresh water is dwindling in many parts of the world, a problem that is expected to grow with populations. One promising source of potable water is the world's virtually limitless supply of seawater, but so far desalination technology has been too expensive for widespread use. Now, MIT researchers have come up with a new approach using a different kind of filtration material: sheets of graphene, a one-atom-thick form of the element carbon, which they say can be far more efficient and possibly less expensive than existing desalination systems.

Farming on a rooftop

From National Geographic - 

In New York City, farming on a rooftop is not just an idea. Brooklyn Grange farms more than two and a half acres of rooftops in Brooklyn and Queens, and then sells what it produces to New Yorkers. A special soil mixture is used to minimize weight on the roofs and allow rapid drainage during heavy downpours. The farmed rooftops also house chickens and an apiary.

Why we need to keep fossil fuels in the ground

From The Guardian - 

"We need to reduce emissions to keep our planet safe for future generations - the science is clear. However, it can be quite hard to get your head around how to do that. Here's a very simple idea from writer and climate campaigner, Bill McKibben: keep fossil fuels in the ground. If we were to burn all the fossil fuel reserves we currently know about, experts forecast the Earth's temperature would warm by more than 2C and have catastrophic effects. Guardian journalists explain the 'keep it in the ground' theory in easy to understand terms."

The story of a spoon

From GreenPeace -

The Story of a Spoon charts the story of a plastic spoon, from the Big Bang to the Bin Bag, and aims to raise awareness of the effects of over-consumption in our society. This video is an appeal for people to take a moment to think about how the stuff we buy came into existence, and what happens to that stuff when we no longer have use for it.

Seven Billion Dreams. One Planet. Consume with Care.

Leonardo Dalessandri via the UNEP - Living within planetary boundaries is the most promising strategy for ensuring a healthy future. Human prosperity need not cost the earth. Living sustainably is about doing more and better with less. It is about knowing that rising rates of natural resource use and the environmental impacts that occur are not a necessary by-product of economic growth.
