Humans are now consuming over a quarter of the biomass produced each year by plants on land, leaving too little for wildlife and putting at risk the biosphere on which all life on Earth depends. To keep the planet in a suitable state for civilisation, we should be using no more than a tenth of plant biomass for our food and fuel, researchers say.
This means that plans to tackle climate change by using even more biomass, for instance to turn into fuel for aeroplanes, will seriously damage the planet in other ways, says Katherine Richardson at the University of Copenhagen in Denmark, such as by causing more deforestation and species loss.
