"Free Solo" climber Alex Honnold compares fighting climate change to physical training, emphasizing the need for practice and starting small. He suggests the U.S. Legislature is "under-trained" and should begin with initiatives like the Energy Innovation and Carbon Dividend Act. Honnold views any effort to reduce carbon emissions as a step in the right direction, endorsing this bill as a crucial first step.

In an October 2013 interview with Bill Moyers, author Wendell Berry—hailed as a "prophet of responsibility" and "passionate advocate for the Earth"—shared his views on leadership.

Berry believes true leadership emerges from the bottom up. It involves individuals who identify a need and act on it. He asserts that success is not the primary concern; rather, the fundamental question is, "What's the Right Thing to do?"

Climate change demands urgent action from the world’s largest corporate emitters and their investors. Ceres, a sustainability nonprofit, is at the forefront of this effort, driving progress at the necessary speed and scale.

Mindy Lubber, CEO and President of Ceres since 2003, is a global thought leader inspiring institutional investors and corporate executives to integrate sustainability into decision-making. Under her leadership, Ceres has significantly grown in influence, helping shift the climate conversation to focus on jobs and the economy. She received the UN 'Champions of the Earth' award and was recognized on Barron’s list of most influential women in U.S. finance.

Prior to Ceres, Lubber served as a Regional Administrator at the U.S. EPA. This talk was given at a TEDx event. Learn more here.

Pro-athletes are entertainers, and their definition of health differs from the average person's. Our bodies constantly expend significant energy just to function; for instance, about 1,400 calories daily are used simply to keep us alive. This inherent energy cost, a legacy from ancestors who conserved energy for survival, explains our natural tendency to avoid unnecessary physical activity, even with modern access to food.

The Northern White Rhinoceros is functionally extinct due to poaching, with only two individuals remaining. A video featuring Dr. Barbara Durrant explores whether the San Diego Zoo Safari Park's "frozen zoo" can reverse this. This unique biotech facility aims to use in vitro fertilization to implant a Northern White Rhino embryo into a closely related Southern White Rhino. If successful, this groundbreaking procedure could rescue critically endangered species and potentially resurrect extinct ones.
