Late last year, Reuters reported that the U.S. Defense Department plans to fund mining and processing operations for rare earth elements—a class of minerals for which China dominates the global market, producing over 80 percent of the world’s supply. In the past, China has restricted exports of rare earths, and recently threatened to do so again. Even with a phase one trade deal hammered out between the United States and China, natural resources are likely to remain a point of geopolitical tension.

Once a designated “recycling bin” for the world’s post-consumer scrap, China said no more when it instituted a ban on scrap imports in 2018. Countries that previously sent bulks of waste to China, such as plastic, paper, and electronics, are grappling for solutions in the face of China’s “Operation National Sword.” For example, U.S. municipalities that shipped 4,000 shipping containers per day in 2016 to China are now investing in incinerators or cutting recycling programs altogether. 

By 2050, the UN estimates that 52 percent of the world’s population will be at risk for water insecurity. Climate change is threatening water availability through increased temperatures and drought, unpredictable rain, and the growing threat of more pollution. Globally, most wastewater reenters the water cycle without being treated, introducing dangerous unseen particles including pharmaceuticals, diseases, and larger waste products such as plastics.

The voluntary use of family planning, among its many benefits, is good for sustaining the healthy ecosystems that support all wild plant and animal species. This should be common sense. If your mission is environmental conservation, you should want to help remove barriers to reproductive health services, so that all women can space wanted pregnancies and avoid unintended ones.

Roughly 20 organizations wield some management authority in the high seas, but none of them have conservation as their core mandate, said Liz Karan, Senior Manager of the Protecting Ocean Life on the High Sea Campaign at the Pew Charitable Trusts. She spoke at a recent Wilson Center event hosted by the Polar Institute and Environmental Change and Security Program. The discussion revolved around aspects of a proposed global treaty on conservation and sustainable use of biodiversity in areas beyond the jurisdiction of any country. “The high seas treaty comes in as an opportunity to put conservation at the focus of the discussion of how we manage the high seas,” said Karan.

“We are stripping the life away from the blue planet,” said oceanographer, explorer, and author, Sylvia A. Earle. She keynoted a recent event on marine protected areas in Antarctica and the high seas co-hosted by the Wilson Center and The Pew Charitable Trusts with support from the Prince Albert II of Monaco Foundation. “Do we want a planet like Mars?” she said. “Most people would say, ‘I don’t think so. I like to breathe. I like water that falls magically out of the sky. I like having a living planet.’”

Oil has played a pivotal role in shaping geopolitics for more than a century. But the rise of electric vehicles and shift toward cleaner fuels means that the world’s dependence on oil could begin to shrink, with both expected and unexpected consequences.

As we move past another Earth Day, environmentalists may be forgiven for assuming that little has changed. The best available evidence points to a rapidly changing climate, declining biodiversity, and fisheries on the verge of collapse. To further complicate matters, the political will to reverse these trends is being stymied by a surge of anti-environmental populism in America, Brazil and elsewhere. When coupled with the continued harvesting of natural resources by big multinational corporations, it is easy to see why environmentalists are crying into their organic kale and quinoa bowls.
