Nowadays we know to avoid mating with close relatives so that your children are healthy. As close relatives accumulate similar genetic diversity, mating between relatives of most species can lead to genetic diseases in their offspring. Humans have a lot of options; there are 7 billion of us worldwide. But how about an endangered species with less than 10 individuals in the wild?
Whilst it might seem like little guys like this don’t have much to smile about these days, being optimistic about the state of the environment is more important than ever, according to Nancy Knowlton (Image Credit: Rosalyn Davis, CC BY-NC-SA 2.0, Image Cropped)
At the very beginning of my PhD, I was in the audience at the STARMUS Festival when American reef biologist Nancy Knowlton gave a talk about Earth Optimism. It came just after the American President had withdrawn his support for the Paris climate agreement, and smiles regarding the state of the planet were hard to come by. So seeing an esteemed member of the scientific community give a reminder that there was hope for one of the earth’s most vulnerable ecosystem was inspiring.
At this year’s International Barcode of Life Conference in Trondheim, I had the chance to sit down with Nancy and talk about why optimism is so important in the face of the many ongoing problems that the planet faces.

If you’ve lost track of what’s going on in US politics (very excusable), you might have missed out on yet another issue that is dividing people. I’m not talking about the Mueller report, or gun legislation, or health care. I’m talking about the Green New Deal, named after the New Deal, a compilation of programs and projects that gave Americans jobs after the Great Depression and built quite a lot of infrastructure. The newest “Green” version is meant to do the same following the Great Recession that America has been suffering the aftershocks of since late last decade. An initiative sponsored by Democrats, the Green New Deal has come under fire from both sides for a wide range of reasons. While the movement for action against climate change is a global phenomenon, I am going to give a brief synopsis of what the Green New Deal represents in the US, and why it has been the subject of so much controversy.
