Climate change and invasive species are jeopardizing already endangered and threatened species, prompting the U.S. Fish and Wildlife Service (FWS) to finalize its 2023 rule allowing experimental populations to be introduced into habitat outside their historical range, as long as the areas are capable of supporting the experimental population.

Since passage of the early natural resource protection laws and regulations in the United States decades ago, legal, technical, and economic practitioners have been challenged with understanding the ever-changing and ever-evolving environmental law and policy landscape. Riveting changes have advanced the position of natural resources and related matters of conservation and biodiversity across domestic and international agendas, in corporate, government, and public interest agendas, and in the lives of everyday citizens.

December 2023 marked 50 years since the Endangered Species Act (ESA) was signed into law. The ESA has proven resilient to numerous legal challenges and saved many species from extinction. But its overall success has been debated, as the list of endangered and threatened species continues to grow, and only 54 species have been taken off of the list completely. On October 26, 2023, the Environmental Law Institute hosted a panel of experts who explored the successes and shortcomings of the statute and discussed what might happen next as climate change increases the risk of extinction.

U.S.-Canadian management of marine migratory species is a particularly rich place to understand the complex relationship between migratory science, conservation, and law. The two nations share a large border, have a long-lasting historic friendship, and already collaborate extensively. However, the relationship is not without contention. The substantial economic interests in the oceans and differences in governance structure have not infrequently frustrated efforts at cooperative management.

Despite five decades of experience, there is a considerable gap in legal and empirical study on the impacts of the National Environmental Policy Act (NEPA). Proponents of reform often claim NEPA litigation is a major obstacle for federal actions; others have concluded litigation is not a major contributor of project cost escalation or delays. This Article studies the incidence and conditions of infrastructure project litigation under NEPA, using a data set of 355 major transportation and energy infrastructure projects that completed a federal environmental study between 2010 and 2018.

The Metals Company (TMC), sponsored by the Republic of Nauru, has made public its intention to be the first company to exploit polymetallic nodules, which contain minerals needed for electric batteries, from the deep ocean’s seabed. Nongovernmental organizations and national governments have objected to these proposed actions, with many calling for an outright ban. This Article offers a case study evaluating the parties’ respective claims in favor of, and in opposition to, permitting the proposed mining activities under the current legal framework.

Since 2017, 115 North Atlantic right whales (NARWs) have been documented dead, seriously injured, or sporting sublethal injuries and illnesses. Scientists refer to this phenomenon as an unusual mortality event, and assert that entanglement and vessel strikes are the leading causes. Fewer than 350 NARWs remain, and it is estimated that only one-third of their deaths are documented. Experts claim that only “quick and decisive action from humans” can ensure the species’ survival. Some proposed regulations will affect where and how the relevant fisheries are able to operate.
