Where Kids Fought Plastic Pollution—and Won

In order to encourage people to properly dispose of their waste, New Delhi Municipal Council (NDMC) has installed smart vending machines for recyclable waste at Connaught Place and India Gate. In return for making the sustainable waste choice, users receive monetary rewards via e-wallet.

Shredded coconut husk, known as Coir, is becoming a popular material for shoreline restoration projects. It’s typically used to trap sediment while protecting vegetation and wildlife from the force of waves. Once the vegetation has several years to flourish, the natural coconut fibers will have decomposed.

What do you get when you combine the efforts of an engineering company with an energy company? In the Netherlands, you get a new type of environmentally sustainable roads. PlasticRoads, a piloted initiative in the city of Zwolle, uses discarded plastic to build bike paths that help cut down on plastic waste.

Across the country, projects that mine landfills for reusable metals and soils are underway. Can such mining prove profitable enough to spur similar efforts on a grand scale? So far, some projects have seen profits while others have not. But as society increasingly values pollution and greenhouse gas reduction, incentives for refuse mining can only grow.

In Jamaica, locally-led coral nurseries are working to restore the coral reef that have been lost to natural and manmade disasters. These organizations have small coral gardens where they can grow free of danger and when they’re big enough, are transported to a reef. With coral and fish being so codependent in the underwater ecosystem, the regrowth of coral has meant an increase of fish and fishing for the country, which many people rely on for their livelihood.

In Eskilstuna, Sweden, there is a different kind of shopping mall – one that sells used and upcycled goods. In an effort to combat consumerism and bolster sustainability, the mall, called ReTuna, is nicely curated and organized, making second-hand shopping mainstream. The mall sees 700 people each day, on average, and has sold nearly $3.5 million worth of items.

As climate changes causes seawater to flood land and increase the salt content in soil, farms in Scotland and the Netherlands are experimenting with using the saltwater to grow food. Seawater Solutions is growing crops called halophytes that have a high-salt tolerance and can be eaten or used as material for cosmetics and biofuels. And the Salt Farm Foundation has shown that potatoes, cabbage, and tomatoes can grow in saltwater. These projects can labor intensive, but seawater irrigation could be a viable climate adaptation solution.

A growing number of governments, companies, and nonprofit organizations are working together with new technology and data to identify fishing vessels that are breaking laws and engaging in human rights violations. Using satellite imagery and tracking signals, for example, a philanthropic company and a nonprofit worked with the UN Office on Drugs and Crime to help the Ghanian navy arrest four vessels for illegal fishing practices. Technology by itself won’t stop forced labor and unregulated ships, but it can be helpful for cash-strapped governments looking to increase oversight of their fisheries.

Scientists are testing if adding alkaline substances to seawater can allow oceans to absorb more carbon dioxide emissions. Early tests suggest this could be a potential way to combat climate change, but there are still many questions about how this can scale, how it impacts the natural ecosystem, and if it’s cost effective to implement.

The Ecosphere Restoration Institute received $5 million from the Florida State Legislature to restore the declining seagrasses on 100 acres of the coast. The organization partnered with experts who have permits to harvest the seeds, grow them in a nursery, and replant them in shallow areas. The project will also help prevent manatee deaths, as the animal depends on seagrass as a food source.
