Phosphorous the disappearing nutrient

We better rethink our phosphorus use before we run out of it. Phosphorous is a vital nutrient for humans, animals, and plants and is heavily used as a fertiliser on agricultural fields. Our food production relies on deposits that will most likely run out of phosphorus within the next decades, with little prospects of alternatives. How will we be able to fertilise our crops in the future?

Permafrost soils and carbon cycling

Permafrost soils make up 15 % of the global land cover and store more than 822 petagrams of carbon in their upper most three centimetres alone (the weight of 182,000,000,000 adult elephants). When comparing this with the annual carbon dioxide emissions of an average German citizen of approx. 2.4 tons C per year1 it becomes clear that we need to prevent these soil from breaking the masses of carbon within these soils. Warming of permafrost leads to the release of carbon, making them a source of the greenhouse gasses carbon dioxide and methane.
