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.

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.

In a preview of Moyers & Company, climate expert Anthony Leiserowitz draws an analogy between small shifts in global average temperature and slight changes in human body temperature. He explains that just as a few degrees can signal serious illness, similar small climate shifts can have profound implications.

Sristi Kamal, Oregon Representative for Defenders of Wildlife, testified for House Bill 2548, which proposes a study to fund wildlife crossings and safe passage structures on Oregon highways. The goal is to reduce collisions and protect ecosystems.

Kamal emphasized the severe economic and ecological impacts of wildlife collisions, including property damage, human injury, and animal loss. Collisions hinder species' movement, food access, and genetic diversity. A neighboring state estimated $2.5 million in annual collision costs on just 12.5 miles of highway. She argued the study is crucial to finding solutions, demonstrating that passage benefits will far outweigh initial investment, preventing further losses. Kamal urged continued engagement in the Oregon Legislative session to support better wildlife policies.
