Mark Carney warns that climate change will lead to financial crises and falling living standards unless companies (have to) come clean about their current and future carbon emissions (Report, 30 September). In the same issue George Monbiot notes that there is water flowing on Mars and asks if there is intelligent life on Earth. Monbiot also reminds us the world has lost half of its vertebrate wildlife in the last 40 years. It’s surely no coincidence that the human population has doubled in our lifetime (we were born in the 1940s). Sadly, population control seems to have become an issue that we are reluctant to discuss.
As biologists, we know that great population growth of a species is frequently ended by a cataclysmic population crash. Is that what we want? Climate change is being driven not just by what we do but by the sheer numbers of us doing it. We are already seeing crop failures, desertification, soil impoverishment and water shortages.
