As humans have evolved, so has our ability to drastically alter the planet we call home. In this collection of talks from the CARTA symposium, "Humans: The Planet-Altering Apes" you will learn about specific examples on how humans have changed Earth and what can be done to prevent its cataclysmic demise. Walter Willett will discuss how climate change is having devastating effects that will undermine our ability to feed the world’s growing population. Jessica Thompson talks about humans transformed the environment and the damage it has done to our ecosystem. Finally, David Tilman addresses the global alteration of Earth's nitrogen cycle, and what it means for u as a species moving forward.

As part of the 2022 Carbon Sequestration Symposium at California State University, Bakersfield, Climate Now founder and host James Lawler moderates a panel discussion on how to capture and store carbon dioxide in order to meet climate action goals. The panelists are Ken Haney, California Resources Corporation Bakersfield, Lorelei Oviatt, director of Kern County Planning and Natural Resources and Sarah Saltzer, Managing Director for Stanford Center for Carbon Storage and the Stanford Carbon Initiative.

Su-Chun Zhang, M.D., Ph.D., shares how neural transplantation cell therapies can be used to treat neurological conditions such as Parkinson's disease. Series: "Stem Cell Channel" [Health and Medicine] [Science] [Show ID: 38203]

This CARTA public symposia addresses specific examples of how humans have drastically altered the planet. Acknowledged experts discuss clearly defined global-scale negative impacts on planet earth, our life support system (other than climate change, population growth and infectious diseases, which are well-known). Each talk succinctly describes a specific impact, the role that our species has played, and concludes with ongoing or potential approaches to mitigation. In the process, we come full circle to Anthropogeny, asking how a single species could have evolved the ability to so drastically alter the entire planet.

There is increasing awareness that health disparities are largely a result of the socioeconomic position in which you are born, the housing and neighborhood where you reside, and the accessibility of educational and job opportunities. These are known as the social and structural determinants of health. By the time a person arrives at a hospital, their health outcome or their chance of survival may have already been pre-determined. Can technological advances in health devices and health-care delivery mitigate the social and structural determinants of health and eliminate disparities?

Why does history keep repeating itself? And what can cats tell us about this? Ashley Poust, Ph.D., is a paleontology researcher at the San Diego Natural History Museum. He focuses on vertebrates and evolutionary biology and explains how the study of extinct cats, like the sabertooth, can help us reconstruct ancient environments, gain a better understanding of our origins, see deeper into life's processes, and at the highest level, have a new view of the world.

What challenges does aging pose to individuals and society at large? What causes aging at the cellular and molecular level? What if we could trick stem cells into thinking they were young again? If so, could we leverage stem cells to help live longer, healthier lives? These are just some of the fascinating questions researchers are exploring in today's closer look at the aging process. Robert A.J. Signer, Ph.D., and Shiri Gur-Cohen, Ph.D., examine aging at the molecular and cellular level to show how stem cells may be the key to preventing age-related health problems.

Climate change is an existential threat. The U.S. will face more frequent and extreme disasters in the coming years due to climate change. How can we harness the power of technology and indigenous knowledge to reduce risks to save lives and property, especially for the most vulnerable communities? This program looks at wildfires, one of California’s biggest climate threats, how to optimize the state for a transition to clean energy, and how we can be good stewards of our natural resources.

The ocean is a critical component of climate solutions. Not only does the ocean have the potential to provide food security, but it can provide critical minerals for the energy transition, species with biopharmaceutical and biotechnology potential, a source of income through sustainable tourism, and innovation of renewable power technologies. Samantha Murray, Executive Director of the Marine Biodiversity and Conservation program at the Scripps Institution of Oceanography, and Amanda Netburn, Assistant Director for Ocean, Science and Technology for the White House Office of Science and Technology Policy, discuss how further exploration of the ocean may help scientists learn more about future climate solutions and improve biodiversity conservation.

Through the Earth Microbiome Program and complementary efforts, we have sampled a broad range of microbiomes from across the planet. All microbiomes that have been studied are impacted by human activity — the effects of industrialization on the human microbiome are best characterized, but capture of animals in zoos, domestication, modification of soils through agricultural practices, and modification of freshwater and marine microbiomes have also all been well characterized. Indeed, the pervasive role of environmental microbiomes in biogeochemical cycles necessary to sustain life led to a position paper entitled "Scientists’ warning to humanity: microorganisms and climate change”, the title of which speaks for itself. However, there is hope. Efforts such as the Microbiota Vault will be especially important in this respect, but also new monitoring and modeling approaches will help us understand where to look globally for the best specimens and microbes to preserve.
