The field of synthetic biology, which is known by some as extreme genetic engineering – that's a name mostly used by people who don't like it. It amounts to a set of tools that humans have developed to be able to very precisely and accurately change the genetic code, the DNA of living organisms in order to get those organisms to do things that humans want. So the applications in medicine are predominantly devoted to trying to make us healthier people, and they range from some really exciting work on tumor biology to work on the microbiome, which is all of the thousands and tens of thousands of species that live on our lips, our mouths, our guts, our skin. And in agriculture, it's primarily directed at crop genetics, trying to improve the productivity of crops, the nutritional value of crops, the ability of crops to respond to climate change, and a whole variety of other things. Some people may have heard of one of these tools called CRISPR used to very precisely alter the sequences of DNA.

Global Leader in the Study of Present-Day Extinctions & Biodiversity
Founder & Director of Saving Nature

It's a complicated issue. I think a lot of those bird disappearances come from the fact that we have massively intensified our agriculture. Large areas of North America and Europe are now under intense agriculture. They are sprayed with a whole variety of pesticides, which I think is also responsible for the fact that many insects have disappeared, so species that depend on farmland have clearly declined dramatically, but it isn't all birds and there is a piece of this complicated story that involves water birds. Herons and egrets and ducks. Those species both in North America and Europe, are now much more common than they were 30, or 40 years ago. That comes from active conservation of protecting wetlands, making sure we don't shoot our wetland birds. So it’s not all doom and gloom. There are some success stories. There are many things we can do. I think 50 years ago, there were only something like 300 bald eagles in the lower 48 states. Bald eagles are now nesting in every state apart from Hawaii. Our conservation efforts have done a great job.
