Egypt’s Gebel Elba National Park is, by all accounts, a spectacular place. But it better be to justify the fuss it takes to visit. First you have to apply for a permit. If that’s approved (and almost none have been in recent years), you need to travel with an approved tour operator. Even then, you must be accompanied by police at all times.

The Klamath River Dam removal, slated for early 2024, is a significant milestone in the journey towards bringing back healthy rivers in the United States. This action will restore nearly 300 miles of river habitat in the Klamath and its tributaries across Southern Oregon and Northern California, allowing salmon, a critical source of economic and nutritional value for the local communities, to return. As the world’s largest dam removal and river restoration project in history, this project will have lasting impacts on the health of this river and represents an opportunity for building momentum to continue global river protection and restoration.

The Arctic is believed to be a pristine environment, far removed from littered city streets and toxic industrial emissions. I study human pollution and I found it hard to believe that my fellow researchers and I would find so much litter out here. It was even harder to believe that what we uncovered closely resembled the contents of my own closet, over 3,000 kilometers (2,000 miles) away in Toronto.

In every Chinese city, there is an army of motorcycles and mopeds weaving through the traffic jams, and sometimes even venturing on sidewalks, to deliver millions of food and e-commerce orders each day. Meituan, one of China’s most popular food delivery apps, delivers 30 million orders a day, serving up 100 million plastic containers. According to Greenpeace, e-commerce and express delivery in China generated 9.4 million tons of packaging waste in 2018 and will likely triple to 41.3 million tons by 2025.

To prevent mass extinctions and bolster resilience to climate change, scientists warn that we must protect at least 30 percent of our oceans, lands, rivers, lakes, and wetlands. To safeguard global biodiversity, the “30 by 30” initiative aims to protect 30 percent of land and oceans by 2030. However, commitments on paper are not enough. World leaders must act strategically in implementation to ensure the most crucial ecosystems are protected. Implementation policies for 30 by 30 must also avoid unintentional harm such as exacerbating conflict over resources, excluding Indigenous and local groups from land management, and neglecting environmental protections for the remaining 70 percent of land and oceans.

“When we started out, people thought it was weird. ‘Why are you integrating people and animals and why are you integrating human health and animal health?’” says Kalema-Zikusoka, founder of Conservation Through Public Health (CTPH), in this week’s New Security Broadcast. Indeed, health infrastructure and conservation have long been organized around distinct silos. “Donors were focusing on single sector funding, and government departments were aligned along single sectors,” says Kalema-Zikusoka.

On my first tour of a Cambodian minefield in 2010, the demining supervisor of the platoon of deminers brought me through a tapioca field where heavily armored men and women stood in lines. I was not allowed beyond the bright red signs with skulls and crossbones. Wearing bulletproof helmets, masks, and aprons, they slowly and tediously walked through the field, using a metal detector to sweep the ground in front of them, the sun reflecting off the long plastic visor. To avoid the heat of the Cambodian sun, they began their work early in the morning. In the golden hour of sunrise as dawn gilded the fields, the sounds of a distant Buddhist temple surrounded us with chanting. I commented on how beautiful it was.

With white sandy beaches, cerulean waters, and lush jungles, Indonesia’s Raja Ampat Islands are some of the world’s most beautiful islands—and currently under threat from a growing plastic waste crisis. Covering 40,000 square kilometers of land and sea off the northwest tip of West Papua, Raja Ampat lies at the intersection of the Indian Ocean and Pacific Ocean tides in a biodiversity hotspot known as the Coral Triangle.
