Actually I do support a charity, DefendersofWildLife.org. They help protect endangered species.
The Awa are a distinctive-looking, diminutive forest people, smaller than any of the dozen other Amazon tribespeople I have met. Reduced size is adaptive in a rain forest. You can move around more easily and unobtrusively. Not only humans but other species are smaller in rain forests.
Clean air and water, a diversity of animal and plant species, soil and mineral resources, and predictable weather are annuities that will pay dividends for as long as the human race survives - and may even extend our stay on Earth.
So I think as a biologist I would like us to focus on this planet and finding solutions to sustaining humanity, to improving people's lives globally, but doing our absolute utmost to preserve as much biodiversity as we can, knowing that we have already been responsible for the loss of thousands of species.
The colour of a British wood in autumn is predominantly yellow. There are relatively few European trees which have red leaves in the autumn. But there are splashes of crimson or rust-red colours from a few indigenous trees, like the rowan, as well as from introduced species, like the North American red oak.
The fate of the vast majority of species on this planet has been extinction, eventually.
Just as your own existence is unlikely and far from inevitable, the evolution of modern humans as a species depended on a whole string of chance events - some happening in the environments our ancestors inhabited, and some inside their own bodies, including random mutations in their DNA.
Babies and young children are like the research and development division of the human species, and we grown-ups are production and marketing.
