"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 - 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."

"Many of us are now aware that bees are in trouble due to manmade changes to the environment. Large-scale industrial agriculture, of course, means that often there are no floral resources over very large areas of farmland, and bees' flexibility in locating food sources of course can cope with that to some extent because they're very good at locating patches, but this ability only goes so far. Of course, if there are literally no flowers left or very few, then their learning ability won't help them very much."

Lars Chittka is professor of sensory and behavioral ecology at Queen Mary University of London, where he founded a new Research Centre for Psychology in 2008 and was its scientific director until 2012.

His discoveries have made a substantial impact on the understanding of animal intelligence and its neural-computational underpinnings.

"I think maybe the critical issue here is the governance aspect which I think is one of the core sources of many of the greatest threats to human civilization on the planet. The difficulties we have in effectively tackling these global governance challenges. So global warming, I think, at its core is really a problem of the global commons. So we all share the same atmosphere and the same global climate, ultimately. And we have a certain reservoir, the environment can absorb a certain amount of carbon dioxide without damage, but if we put out too much, then we together face a negative consequence."

Nick Bostrom is a Swedish-born philosopher with a background in theoretical physics, computational neuroscience, logic, and artificial intelligence, as well as philosophy.

“Humanity needs to do three things if it wants to continue to flourish, and it will. The three things that humanity needs to do are decarbonize the global economy, drawdown, capture, harvest much of that heat-trapping pollution that we've already pumped into the atmosphere over the past hundred years because as long as it's up in our atmosphere, we're going to have continued warming. And the third thing that humanity needs to do is become more resilient to the impacts of climate change, which unfortunately will continue for the next several generations at least, even as we succeed in decarbonizing the global economy and harvesting that heat-trapping pollution from the atmosphere. So these are the three things that have to happen. These three things will happen. The open question is how rapidly will they happen? Any business that can play a vital role in making any one or two or all three of those things happen, those are businesses that are going to flourish going forward. And any business that's sitting on the side and not contributing to one of those three areas, I really think they will become increasingly irrelevant, if not completely antiquated and increasingly understood to be harmful.”

"So this was maybe nine months after the fire in Notre Dame, and I had been struck visually by the fire, the yellow smoke, which is a telltale indicator of lead. The fact that 400 tons of lead constituted the covering of the roof of the cathedral. And a lot of that had volatilized, presumably, but no one really knew how much. So that got me thinking, and I happened to be in Paris at the time, so I thought if it's so much lead, could it be that it affected the population living within say a kilometer of the cathedral? I thought there wasn't really a lot of clear information about what had happened, and what had been measured. I thought some more openness and transparency was needed."

Geochemist Lex van Geen is a research professor at Lamont-Doherty Earth Observatory and is member of the Earth Institute at Columbia University. His research focuses on ways to reduce the impact of the environment on human health. For two decades, he coordinated earth-science on the origin and health effects of elevated levels of arsenic in groundwater. His other projects focus on fluoride in groundwater in India, bauxite dust in Guinea, or soil contaminated with lead from mine-tailings in Peru, and fallout of lead over Paris following the fire in Notre Dame. Dr. Van Geen is a firm believer in the more widespread use of field kits by non-specialists to reduce exposure to environmental toxicants.

“When you dig into the medical literature, 7 out of 10 of the leading causes of death in the United States are diet-related chronic diseases. And so one of the hopeful messages that I think comes out of The Hidden Half of Nature, Growing a Revolution, and What Your Food Ate is that what we do to the land, essentially we do to us. And what's good for the land is good for us."

David R. Montgomery teaches at the University of Washington where he studies the evolution of topography and how geological processes shape landscapes and influence ecological systems.

He is the author of award-winning popular-science books (King of Fish, Dirt, and Growing a Revolution) and co-authored The Hidden Half of Nature, The Microbial Roots of Life and Health and What Your Food Ate: How to Heal Our Land and Reclaim Our Health with his wife, biologist Anne Biklé.

"The dinosaur extinction - dinosaurs didn't really have much to say about it. A meteor crashed into the earth and wiped them out. We, on the other hand, are creating quite an extinction right now. And we actually could do something about it, but we're not going to do anything about it because we're just greedy. We always just slough it off to the next generation. ‘They can fix it,’ we say. I'm a war baby, right? I was born in 1946, and by 1964, when I graduated from high school, our generation was going to fix everything. And yet we became the biggest consumers in the history of the world. So we didn't fix anything, we just made a bigger mess. So, I don't think we can leave it up to anybody because everybody wants a piece of the pie."

"When we were working in Panama with E.O. Wilson on the Panama Museum of Biodiversity for the world's first museum of biodiversity, we went into the jungle with E.O. Wilson, and he explained that there's only one thing on the planet and that's life. And life has an experiment going in form. We are one of those forms, and over 99% of all the experiments have gone extinct. So less than 1% of all the forms that ever existed now exist. And we're living through another one of the mass extinctions. Many of those are going to go extinct. We may be one of those, and life goes on. Life will go on."

"I think we have to recognize that we're having other impacts on biodiversity, not just eliminating it but also altering it - what it looks like, what constitutes it. I think recognizing that is vital, really. We've created a human planet, a planet that is increasingly organized to serve one particular species. And the rest of life has to work around that, but I feel that there are lessons to be learned in observing how the rest of life is doing that kind of work of adapting and learning to live on a human planet. Learning, I'd say, better than we are currently, to live sustainably on a human planet. Where we're going at the moment, the future does not look very good, and we need to adjust our course."
