We are part of Nature, not separate from it. We rely on Nature to provide us with food, water and shelter; regulate our climate and disease; maintain nutrient cycles and oxygen production; and provide us with spiritual fulfilment and opportunities for recreation and recuperation, which can enhance our health and well-being.Nature's constituents such as ecosystems and the biodiversity that are embodied in them are therefore assets.Yet Nature is more than an economic good: many recognise its intrinsic worth and argue that it has moral worth too.This landmark report explains the current state of play in relation to biodiversity loss and outlines a sustainable path to deal with this problem, one that will require us to change how we think, act and measure success.The report was originally commissioned and published by HM Treasury.
