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.  

In a giant building filled with dark and humid rooms, some 2 billion cockroaches are scampering around piles of food. This is not a scene out of a horror film, but an innovative business venture to help Jinan, a “small” city of 9 million in northeast China, deal with its overfull food waste. Jinan produces more than 6,000 tons of solid waste each day, and like most Chinese cities, 50 to 70 percent of it is food waste. To divert more organic waste from landfills, the municipal government partnered with the Zhangqiu District Food Waste Processing Center to use cockroaches to dispose of the 60 tons of food waste daily from district restaurants and companies as well as households in 40 waste-sorting pilot villages. The company is highly profitable as it gets the food waste for free from the city; and city then gives subsidies for each ton of food waste processed. The company also sells some 2,433 tons of dead cockroaches each year as animal feed additives. However, the small six-legged workers only devour some 100 tons of food waste per day even with expansion plans for two new factories, a mere 1.6 percent of the city’s total  waste. Cockroaches alone cannot conquer the city’s food waste challenge.
