Deserts cover a quarter of the earth, nourished by over grazing, poor land management and changing climate. The world population is 7 billion and rising, so available space is getting a little tight. Grassland ecosystem pioneer Allan Savory is on a mission to tackle desertification by rethinking land and livestock management in a holistic approach that takes into account nature’s complexity and our own as well.

The Great Pacific Garbage Patch, or the Pacific Trash Vortex, is a vast mass of marine litter trapped in the vortex of currents of the North Pacific Gyre, creating a concentrated “plastic soup” of fine particles, which is increasing at an alarming rate and killing millions of organisms annually.
If, however, you view this unsavoury mass as a resource, it makes sense to harvest it. UK designers Studio Swine and Kieren Jones proposed a “Sea Chair” made from ocean plastic harvested by a trawler a couple of years ago and now household eco-detergent company Ecover have taken up the idea to produce ocean-harvested plastic packaging for their biodegradable detergents.

The city of Adelaide in Australia, located in the driest state on the driest continent on earth, has recently invested 1.8 billion AUD in a new desalination plant with the capacity to produce up to 300 million litres of safe drinking water per day from seawater – approximately half the city’s water needs. But what will happen to all the salt?
