Salmon require cool temperatures to migrate and reproduce. The Clean Water Act (CWA) requires states to develop and implement water quality standards sufficient to produce fishable waters. Nearly a half-century after its 1972 enactment, the modern federal statute’s goal of fishable waters has yet to be achieved in the case of salmon streams.

I magine, on account of an economic downturn associated with massive defense spending, or a change in regulatory philosophy, or a pandemic, the U.S. Congress enacted legislation duly signed by the president to sell virtually all federal wild lands to the highest bidder without restriction. Would such action be constitutional?

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.

Per- and polyfluoroalkyl substances (PFAS) are a toxic, environmentally persistent class of chemicals that have been used widely in consumer products. Despite growing evidence of adverse health effects associated with PFAS exposure, the U.S. Environmental Protection Agency has not yet promulgated a legally enforceable standard for any of the individual chemicals in the PFAS group. This has resulted in largely unrestricted disposal of PFAS waste and dispersal of these persistent chemicals throughout the environment.

The U.S. Supreme Court’s opinion in Weyerhaeuser Co. v. U.S. Fish & Wildlife Service raises important questions about the scope of the Endangered Species Act’s (ESA’s) protections for critical habitat. Foremost among them is a question one might think was long settled: what is “habitat”? In a short ruling, the Weyerhaeuser Court opined that “critical habitat” must first be “habitat,” but it did not attempt to define exactly what habitat is or how much deference the U.S. Fish and Wildlife Service should get on what is both a biological and policy question.

This Article, adapted from Chapter 16 of What Can Animal Law Learn From Environmental Law?, 2d Edition (ELI Press, forthcoming 2020), explores existing and potential wildlife conservation policies that could play a vital role in mitigating global climate change. It describes how climate change is impacting wildlife and biodiversity around the globe and reviews the history and current state of U.S. policy, including how the federal government currently manages climate change issues under the ESA.

Section 401 certification and permit conditioning under the Clean Water Act is one of the most significant tools for states to influence federally permitted activities involving discharges into navigable waters. However, states are required to set conditions within one year or they forgo their ability to do so. In practice, the one-year review is difficult for states to meet and led to a common practice known as “withdraw and resubmit” in which states could reset the clock. But in Hoopa Valley Tribe v. Federal Energy Regulatory Comm’n, the D.C.

The Endangered Species Act defines an endangered species as one at risk of extinction “throughout all or a significant portion of its range.” The U.S. Department of the Interior (DOI) has repeatedly defined “significant portion” to mean an area of the range essential to species persistence. This definition is redundant, and various iterations of the definition have been struck down in the past. At the same time, other proposals to list a species only in a portion of its range fail to satisfy the statutory requirements.

Marine litter is human-created waste that has been discharged into the marine environment, including glass, metal, plastics, and other debris. According to data compiled by the United Nations, the equivalent of a garbage truck filled with plastic is dumped into the ocean every minute—more than 8 million metric tons per year. On November 11, 2019, the Environmental Law Institute hosted an expert panel that explored recent U.S.

Our country's landscape has changed dramatically over the last 50 years as a result of numerous governmental policies and subsidies that encourage low-density development commonly referred to as "sprawl." Sprawl results in environmental problems ranging from air pollution to wetland degradation. Our countryside is disappearing and becoming more fragmented, while urban areas are simply neglected. Moreover, this type of growth, which has gone unchecked for the latter half of this century, increases traffic congestion, strains public budgets, and deteriorates our quality of life.
