Changing weather patterns, with stronger storms and droughts, demand land restoration. We need to free land to absorb flooding, recover hydrology, and enhance natural systems for CO2 sequestration.

The automotive age has brought mobility at a steep environmental cost. Gas cars are disastrous, leading to ecosystem loss as paved surfaces cover soil and absorb heat; EVs don't solve this land-use issue. Additionally, three-quarters of arable land converted to animal agriculture compounds this recipe for disaster.

Amara Ifeji, 20, recognized the lack of environmental opportunities in marginalized communities. In 2018, she began facilitating environmental learning for students of color. She later became a director for the Maine Environmental Changemakers Network, an intergenerational group of 400+ youth promoting a just, inclusive, and equitable environmental movement.

Amara elevates youth voices in state and federal policy. In 2021, she coordinated Maine’s first climate education summit, gathering young people’s visions. This led to her helping create and implement a bill funding over $2 million for climate education in the state. Learn more at broweryouthawards.org.

Our bodies are naturally wired to conserve energy, a trait inherited from ancestors who faced food scarcity. Even today, we expend about 1,400 calories daily just to stay alive, leading us to instinctively avoid unnecessary physical activity despite readily available energy sources. This perspective, distinguishing between athletic performance and true health, is explored by Daniel Lieberman, a Harvard professor of Human Evolutionary Biology.

Releasing Tuesday, November 9, "The Story of Electronics" exposes the high-tech revolution's collateral damage: 25 million tons of e-waste, poisoned workers, and public costs. Host Annie Leonard guides viewers from gadget production in mines and factories to their grim end in Chinese recycling shops. The film advocates a "green 'race to the top'" for designers to create long-lasting, toxic-free, and easily recyclable products.

The Electronics TakeBack Coalition, promoting green design and responsible recycling, partnered on this production.

Concentrated Solar Power (CSP) offers a powerful solution to fuel the future, capable of replacing fossil fuels for industrial processes like steel and cement manufacturing, thereby reducing global carbon emissions. CSP systems use arrays of revolving mirrors (heliostats) to precisely reflect sunlight into a central receiver, generating immense heat.

Recent advancements in AI and machine learning are making CSP technology smarter, more efficient, and increasingly affordable. Innovators like Heliogen, backed by Bill Gates, leverage software to optimize mirror control, making solar energy cleaner and cheaper than fossil fuels. This progress paves the way for global adoption, as explored in the "Hard Reset" series.
