The UK government’s official climate advisors recently reported that the country’s greenhouse gas emissions must fall to zero by 2050 in order to tackle the growing threat of manmade climate change.However, it seems unlikely that we will be able to reach this target by simply burning less fossil fuel and cutting down on international travel. So what else can be done?Environmental charity Rewilding Britain thinks that the answer is to let large areas of the country return to their pre-agricultural state to restore natural carbon sequestering environments such as peat bogs, heaths and salt marshes.In this episode of the Science Focus Podcast BBC Science Focus commissioning editor Jason Goodyer talks to environmental researcher Mark Lynas about the potential beneficial effects of rewilding.We now have more than 75 episodes of the Science Focus Podcast, each of which is still well worth a listen.
