Nature is critical for human existence, but it is under increasing stress – because of us. Human activity, such as consumption, eating habits and energy needs, has altered almost 75% of the earth’s surface. Forests are declining at an alarming rate owing to agricultural expansion and climate change, while almost 1m animal and plant species are threatened with extinction1. According to the WWF’s Living Planet Report 2020, global wildlife populations fell by 68%, on average, between 1970 and 2016, with some Australian populations plummeting by up to 97%.
