The Tana River in northernmost Norway is the most diverse Atlantic salmon river in the world. Its native salmon population has declined dramatically and resulted in a fishing ban that has affected indigenous life and distressed the local economy. Concern is mounting over the secondary infestation of Pacific pink salmon, transplanted decades ago, which creates a potential threat to the river’s genetic diversity and challenges the regime structures of international fisheries.

In 2009, when carbon dioxide (CO2) levels were at 387.43 parts per million, the Center for Biological Diversity and 350.org submitted a citizen petition calling on the U.S. Environmental Protection Agency to take steps necessary to institute a national ambient air quality standard (NAAQS) for greenhouse gas (GHG) emissions under §§108-110 of the Clean Air Act (CAA). For 12 years, the petition was simply ignored. Then, the day President Donald Trump left office, outgoing EPA Administrator Andrew Wheeler issued a letter denying the petition.

State wildlife agencies commonly claim they are entitled to manage wildlife under the public trust doctrine (PTD). This assertion is frequently made in judicial proceedings, with state requests that their managerial authority be given due force throughout state, private, federal, and even tribal lands. One might conclude that a rich body of PTD practices and policies exists for wildlife; in reality, the PTD in state wildlife management proves to be ephemeral.

Over the past 50 years, tremendous progress has been made in reducing air pollution under the Clean Air Act. Nevertheless, while air quality has improved greatly for much of the nation, there are still places where the goal of attaining national standards has still not been reached. This is often true in urban locations that are affected by multiple pollution sources; typically, these areas are also environmental justice communities. Recent events have called attention to the urgent need for concrete action to address the many problems of these communities.
