How off-the-grid Navajo residents are getting running water

Washing hands in between contact with patients is one of the most important things a healthcare worker can do to prevent the spread of disease and reduce the rise of superbugs like MRSA. A new technology is increasing rates of hand washing by displaying, via a sensor in an employee's badge, whether the healthcare provider has washed their hands recently.

Ecological toilets that use natural composting to break down waste are simple to construct, waterless and are easy to fix. But as philanthropists are finding, getting these to those that need it most is harder than anticipated.

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.

Although patients go to hospitals to receive medical care, many Americans will acquire infections that did not already have them. The United States as a whole has made modest progress at reducing the rates of hospital-acquired infections. Spearheading the efforts, the Veterans Affairs Medical Centers have devised anti-MRSA strategies to keep patients safe.

New York City black tar roofs cause a number of environmental problems, including air pollution, heat absorption that raises energy consumption, and storm water runoff in the sewer system. Efforts to turn these old roofs into green spaces cool the buildings, enable the containment of more rainfall, reduce sewer discharge, generate energy, and absorb carbon emissions. New York City has a pilot program offering financial help for green roofs.

In war zones, people have a difficult time finding clean water and safe areas to inhabit. Social media, smart phones, and technology applications are aiding in people’s survival. In Aleppo, Syria, the International Committee of the Red Cross posted a map on Facebook to show alternative sources of clean drinking water that reached approximately 140,000 people.

In a country of limited resources — and perhaps for that very reason — preparing for natural disasters is top of the agenda in Bangladesh. Various grassroots, collaborative programs have been put in place over the years to help address many facets of the calamities caused by cyclones, from improved emergency shelters to long-term support for those who lose their livelihoods in the storms.

Clean water and healthy ecosystems are becoming increasingly difficult to come by. With floating islands and other inventions, eco-entrepreneur Bruce Kania thinks that biomimicry - such as reconstructing wetlands and growing biofilms - can tackle the toughest of water problems.

Warming water has led to the collapse of coral reef systems in the western Indian Ocean, essential to fisheries, protecting shorelines, and reducing beach erosion and sea-level rise. Marine scientists from Nature Seychelles, as part of an international project to protect and restore the reefs, are promoting varieties of coral that they have found to be resistant to the rise in temperature.
