Across the United States, ecosystem-related news this week has been dominated by both progress and challenge. According to the League of Conservation Voters, March 2025 marked the first time that renewable energy provided more electricity to the US grid than fossil fuels, reaching 51 percent of total power compared to fossil fuels' 49 percent. This shift demonstrates a significant milestone for clean energy, indicating the resilience of the nation’s transition even amidst policy uncertainty. Notably, Sun Prairie, Wisconsin became the first city in the state to operate all municipal functions—such as street lighting and water pumps—on 100 percent renewable energy, cutting local emissions and costs.

At the federal level, major regulatory changes were announced June 30 as the US Department of Agriculture revised its National Environmental Policy Act regulations. Agriculture Secretary Brooke Rollins stated that these changes are intended to reduce bureaucratic delays in environmental reviews, enabling faster delivery of services and projects vital for rural communities and the health of US forests. The Department rescinded seven agency-specific regulations, resulting in a 66 percent reduction in regulatory requirements. This move follows President Trump’s executive order and is framed as a response to decades of regulatory overreach, with the goal of prioritizing land stewardship alongside efficiency.

Elsewhere, researchers have drawn attention to ongoing threats and surprising resilience within US ecosystems. ScienceDaily recently reported that native turtles are returning to Yosemite National Park after the removal of invasive American bullfrogs, signaling an encouraging recovery of the natural balance. However, more than 3500 animal species remain threatened by climate change, with many risks yet to be fully understood. In Florida, a study revealed that heat-tolerant symbiotic algae could be essential for the survival of endangered elkhorn coral during marine heatwaves, while the largest remaining seagrass beds along Florida’s Gulf Coast appear to be healthy and largely undisturbed.

Internationally, major ecosystem events are shaping global priorities. The 15th Meeting of the Conference of the Contracting Parties to the Ramsar Convention, focusing on wetland conservation, will take place later this summer in Zimbabwe, involving almost 90 percent of United Nations member states. Events like the Future Action Summit in Thailand and the World Lake Conference in Australia further highlight global collaboration toward ecosystem restoration and sustainable development.

Collectively, these developments reveal an ecosystem landscape in flux, marked by policy changes, scientific advances, and local progress. The US continues to make headway towards sustainable energy, while regulatory and scientific communities grapple with the dual imperatives of efficiency and environmental protection. International dialogue underscores the interconnectedness of ecosystem health worldwide, as restoration and resilience remain central themes.
