Nearly two-thirds of the world’s population experiences some level of water scarcity—and an estimated one billion urban residents face unreliable drinking water supplies. This global water crisis not only has been recognized by the United Nations, but also prioritized for action as Sustainable Development Goal (SDG) 6: “Access to Water and Sanitation for All”.

The Arctic was once untouched and pristine. However, over the years, the polar environment has experienced ecological damage caused by extensive resource exploration, military activities, and contamination from sources originating outside of the region. The extent and implications of the human-induced pollution legacy are still awaiting comprehensive estimation, measures, and solutions.

Earlier in 2022, Ecuador’s capital was left “virtually paralyzed” after some 14,000 people, mainly Indigenous Ecuadorians, participated in 17 days of sometimes violent nationwide protests. The actions forced the Lasso government to the negotiating table for a 90-day dialogue with Indigenous leaders. By early September, the parties signed a temporary moratorium on the development of oil blocks and the allocation of new mining contracts.

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 harm that comes to the environment during armed conflict is often permanent, yet the lack of advocates to fight for its protection as they happen creates a deafening stillness. Indeed, this state of affairs has led to the environment to be seen as the “silent victim of war.” Vietnam, Kuwait, Syria, Afghanistan, Ukraine, and several more nations have been permanently damaged due to the destruction of the environment during armed conflict which can persist long after hostilities have ceased.

In 1972, environmental activists, government leaders, and industry experts met in Stockholm, Sweden, for the United Nations Conference on the Human Environment (Stockholm Conference) to plot out a new direction for international environmental governance. Over the ensuing 50 years, countries negotiated successful agreements to shrink the ozone hole and expanded protections for wildlife and ecosystems.

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.

If producing plastic waste were a race, Japan would be rushing for the gold medal. Japan and the United States both rank the highest per capita for plastic packaging waste in the world. Former Prime Minister Shinzo Abe’s administration set a goal to reduce Japan’s plastic waste production by 25 percent by 2030 and recent polls show the majority of the Japanese public wants strong actions to reduce plastic waste. Nevertheless, Japan is not doing enough to stem the tide of plastic entering the ocean. If Japan and the rest of the world fail to act more boldly, global oceanic plastic waste could triple by 2040. Current commitments of governments and corporations would only reduce global plastic leakage seven percent below the business-as-usual scenario. Japan’s current waste management system prioritizes recycling and incineration, encouraging a make-take-waste linear model of plastic consumption. Japan needs a circular economy built on a culture of reduction and reuse instead of single-use plastics.
