In the first decades of the 21st century, those working to assure that earth continues to be a viable home for humanity as well as for all other life have been in a crisis regarding their purpose and direction. This is a departure from the past century and a half, when the giants of conservation and environmental protection—personalities such as John Muir, Rachel Carson, and David Brower— were certain of their cause and the actions needed to sustain it.

This Article analyzes the recent proliferation of “tag-gag” laws aimed at undermining the emerging plantbased and cell-based food industries. It examines potential constitutional challenges to these laws, including those based on the First Amendment, the dormant Commerce Clause, Supremacy Clause, and Due Process Clause, as well as the likely arguments that states will proffer in their defense. It concludes with a discussion of the consequences and implications of various outcomes of these cases, and how animal advocates can responsibly bring these types of constitutional challenges.

In the absence of a national mandate to intensify use of renewable energy, many corporations are increasing their own reliance on renewables. Numerous utilities are likewise transitioning toward wind, thermal, and solar power. But renewable energy continues to face challenges, including battery storage, grid expansion and incorporation of renewables into the grid, initial project costs, and regulatory barriers. How are utilities and energy-consuming companies increasing their renewables portfolios while navigating this terrain?

On March 11, 2019, the National Oceanic and Atmospheric Administration published an advance notice of proposed rulemaking to amend regulations that implement the Coastal Zone Management Act’s (CZMA’s) consistency requirement. This Article places the notice in context, focusing on the CZMA’s role in state review of offshore oil and gas development and its evolution to provide a predictable framework that balances coastal state interests with the nation’s energy needs.

Enhanced oil recovery has generated an immense and growing market for carbon dioxide (CO2), which has uses in manufacturing, medical, and industrial settings. In the next 30 years, these combined end-uses will necessitate a three- to fivefold expansion of existing CO2 transportation infrastructure in the United States. A more flexible, extensive, and integrated CO2 pipeline network is necessary to accommodate this growing demand.

The plastic packaging industry faces mounting shareholder and public pressure to reduce the environmental impact of post-consumer plastic packaging. The recycled plastics market in the United States is positioned for growth; however, developing a reliable supply of post-consumer plastics will be expensive because of problems in the recycling market. Reliance on export markets has limited investment in domestic recycling capacity, local collection programs vary considerably, and many consumers are ignorant about what can be recycled.

In September 2019, in an article entitled “The Market Has Spoken: Coal Is Dying,” Matt Egan of CNN Business wrote, "President Donald Trump has gutted regulations on the coal industry, falsely claimed that windmills cause cancer and installed a former coal lobbyist to lead the [U.S. Environmental Protection Agency] EPA. In the face of those efforts to rescue coal country, America’s aging fleet of coal-fired plants continues to shrink. New plants are not getting built. Trump’s vow to rip up environmental rules has been overwhelmed by an even more powerful force: the free market.
