Humanity's population has surged from 1 billion in 1800 to 7 billion today, now producing enough food for 10 billion. This prosperity, driven by agricultural and water revolutions, comes with significant environmental costs. Daniel assesses the critical food and water challenges of the coming century and explores opportunities for sustainable solutions.

A geochemist and lecturer at the University of Lincoln, Daniel researches the chemical interplay between humans and the environment. His work, published in international journals, investigates how earth's chemistry shapes human lives and how human actions impact nutrient and contaminant processes in soils, rivers, and groundwaters. This talk was given at a TEDx event. Learn more at ted.com/tedx.

Could genomics solve the climate change crisis? Watch the newest video from Big Think: https://bigth.ink/NewVideo Join Big Think Edge for exclusive videos: https://bigth.ink/Edge ---------------------------------------------------------------------------------- Genomics is the study of genes and their functions. The branch of molecular biology presents the idea that the genome can be manipulated for added resilience against harm. Yale professor and editor Daniel C. Esty argues that genetic modification in nature as a way to improve sustainability should be seriously considered. In the book A Better Planet: Forty Big Ideas for a Sustainable Future, Esty and several authors offer actionable solutions for dealing with greenhouse gases, including genomic intervention in nature. ---------------------------------------------------------------------------------- DANIEL C. ESTY Daniel C. Esty is the Hillhouse Professor of Environmental Law and Policy at the Yale School of Forestry & Environmental Studies and the Yale Law School. Known for his innovative policy ideas and commitment to transformative change, Dan served as head of the Connecticut Department of Energy and Environmental Protection from 2011 to 2014 and in several leadership roles at the U.S. Environmental Protection Agency from 1989 to 1993. He is the editor of A Better Planet: 40 Big Ideas for a Sustainable Future (Yale University Press). ---------------------------------------------------------------------------------- TRANSCRIPT: So genomics, the idea that we can intervene with the genome of not just humans but any species in a way that might harden that species, improve it’s resilience to threats like climate change or make it more amenable to various medical approaches so as to ensure there’s a reduction of harm. And it can also be used in plants, for example, to speed up the growth pace and otherwise to provide ways to help harden the species or improve a species contribution to the response to climate change. So many aspects of society have been transformed by technology breakthroughs in the last couple of decades. And I would argue that the environmental arena broadly and climate change in particular had seen very little of that brought to bear despite an urgent need. And I do think suddenly that’s changing. We now have a number of people that are looking at various aspects of the technology world and saying how might this help us achieve a sustainable future. And that is very much a focus of the Better Planet book with a number of authors putting forward both technologies and frames of thinking that might move us towards a climate change answer. One of the most important aspects of this in my mind is the concept of genomics, of thinking about how we do genetic modification as a strategy for improving sustainability. And the chapter in our Better Planet book that lays this out offers examples both in terms of human exposure to public health threats broadly and to climate change in particular and understanding how we might well be able to address individual exposures that differ from the general public with genomic intervention in the future sparing people pain and suffering they might otherwise face. And perhaps even more interesting there are very significant ways that we might see genomic progress in addressing the plant and animal world. I’m thinking in particular of forests which could be a critical sink for carbon dioxide and I do think there are ways that we can make forests grow faster and perhaps serve more successfully as a sink for those greenhouse gases ensuring a better response to the problem and getting us to think about both mitigation, reducing emissions, but also the ability to set up nature as part of the solution absorbing those carbon emissions. ---------------------------------------------------------------------------------- ABOUT BIG THINK: Smarter Faster™ Big Think is the leading source of expert-driven, actionable, educational content -- with thousands of videos, featuring experts ranging from Bill Clinton to Bill Nye, we help you get smarter, faster.

Dr. Daniel Pauly highlights aquaculture's varied impact. Low-trophic species like bivalves (mussels, oysters) and seaweed offer sustainable options. But industrial salmon and other marine predator farming depend on wild fish feed. China's two-thirds share of global fish farming, especially carnivorous species, magnifies environmental impact.

To support sustainable seafood and ocean health, demand low-trophic aquaculture, stronger regulation of open-net pens, and true industry transparency.
