plant and animal species are now threatened with extinction. wildlife populations have dropped on average by 68% since 1970, that is unprecedented, and damage to our ecosystems has a direct impact on others, our livelihoods, food security and health. experts say that protecting those ecosystems is one of the best ways to counter climate change in itself. i think boris engineers by excavating waterholes and fertilising the land. money is the key there is a figure, but for every dollar that governments do spend a nature, $4 governments do spend a nature, $a is spent on agriculture, forestry and fisheries, which exploit and degrade it. i spoke to the director general of the wwf about what steps are being taken to meet the challenge.
