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.

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.
