In May 2019, the United Nations published a comprehensive report on the rapid decline in biodiversity; around 1 million species of plants and animals are threatened with extinction are under threat . Biodiversity loss results from human uses of land and seas, how we exploit other species, climate change, pollution, and the introduction of invasive alien species.
Climate break-down is a key threat, with extreme weather events increasingly affecting all parts of the world, melting icecaps and glaciers. It is too late to prevent much destruction and loss of life but if enough radical action is taken urgently, it may be possible to avoid the the worst effects of runaway climate change.
So what can we do about this?
