  • Turning oil platforms into reefs

    After oil and gas platforms reach the end of their working lives, some are being turned into artificial reefs that can create new ecosystems in the ocean. Since the 1980s, 550 platforms have been reefed in the Gulf of Mexico and programs are springing up to help industry make the switch. These reefs can be home to fish and birds, and studies have shown that some species prefer these structures over their natural habitats. While not all environmentalists agree with leaving the platforms in the water, scientists are working to understanding how similar programs can be implemented in other parts of the world.

  • Giving Mother Nature a Hand

    Cervene Pecky and Dolany, two small towns in Prague, were able to fix their flooding problems through a process known as land consolidation. Prior to the land consolidation, the towns would get flooded by rainwater. Through land consolidation, property owners are able to redraw property lines. Thanks to the consolidation, the field that emptied into Dolany is now covered in grass, trees, and ditches.

  • Clean Water at No Cost? Just Add Carbon Credits

    The company that manufactures Lifestraw, a water purification device, has found a way to distribute their product to impoverished Kenyan families for free, while still making a profit. In the global carbon credit market, businesses receive carbon credits for projects that reduce greenhouse gas emissions. These credits can then be sold to companies who need to offset their carbon emissions, allowing green companies to make a profit off of their small ecological footprint.

  • Can Eggshells Save One of Mexico's Most Polluted Rivers?

    The Lerma river in Mexico is one of the most polluted rivers in the country. Water from the river leaves behind yellow stains and causes headaches and dizziness. To help bring clean, drinking water to the community a scientist and a resident in Lerma co-found the H2O Lerma With Charm collective. One of the things the group does is create filters from eggshells they install in the local wells. Eggshels, which are high in calcium, combined with magnesium can reduce heavy metals in water by 80 percent. The collective has close to 70 members and have installed filters in seven local wells.

  • From 30 Million Cases to Zero

    China’s path to officially eliminating malaria began in the 1950s when a scientist in a government-funded program discovered the ancient Chinese herb Wormwood had been used to treat symptoms for centuries and went on to make the world’s top treatment. Effective coordination across many agencies, treating stagnant water, and widespread use of insecticide nets also limited cases. Today China uses the “1-3-7” method where local agencies are told of any likely case within one day, the case is confirmed within three days, and measures are taken to treat the patient and prevent further spread within seven days.

  • An ancient people with a modern climate plan

    The Swinomish tribe in Washington state is combining traditional knowledge and science to combat the effects of climate change and improve the health of its land, water, and people. In recent years, their salmon harvest has diminished due to warming waters, but they’ve instituted salmon recovery efforts by restoring tidelands and channels and planting trees along stream beds to cool the waters. Their focus on ecosystem and community health could be a model for other Indigenous tribes looking to create their own climate plans.

  • With the Hippo Roller, a revolution in fetching water rolls on

    After realizing the difficulty that people in South Africa were facing when carrying water back to their communities, two South African engineers devised a machine "that brings all the water back in one trip by rolling it." Users report that while it does not perform well on steep terrain, it can carry much larger amounts of water "effortlessly and in a single trip." So far, 60,000 of these large plastic drums have been sold, but the cost of the machine is often a barrier for those who live below the poverty line.

  • How Vancouver is protecting itself from future flooding — with plants

    Large cities like Vacounver and Seattle are increasingly leaning towards "green infrastracture," a method of managing stormwater through natural systems like green roofs and rain gardens that absorb rainwater. Cities have traditionally relied on traditional sewage systems, but in the face of climate change, and more intense storms, its proving to be inadequate. Green infrascture lowers flood levels, filters out pollutants in the water, and regulates city temperature. In Seattle, an early adopter of green infrastructure, rain gardens absorbed 1.5 trillion liters of rainwate.
