Can We Change Our Behavior or are We Stuck?

Israel has grappled with crippling drought for years. But people have learned to use Mediterranean sea water and recycled wastewater to provide the country with enough water for all its needs.

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.

Children coming from abusive households are often reluctant to discuss their past experiences. A Mexican foundation is using animated characters to help abused and ill children speak about their lives.

After the drought hit Australia in the early 2000s, city officials had to start thinking seriously about ways to conserve and creatively store their water. External tanks became the solution, storing rain runoff to create an available source of water for Melbourne residents. This solution may not fit every location, but there are other teachable lessons such as taking radically shorter showers.

Laws in Texas and New Mexico, both locked in the grip of a crippling drought, don't do much to actually encourage citizens to conserve water. New conservation laws and financial incentives are trying to change that.

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.

Harassment on the internet is more accepted but just as harmful as it is in person. RiotGames, a game publisher, decreased abuse by enabling its gaming members to decide and enforce community norms.

Poor people are less likely to make smart financial decisions; however, new research in the U.S. says this is not about intelligence but rather about a brain being overwhelmed with issues related to poverty. To combat that barrier of stress, organizations around the world are making financial decisions easier for people experiencing poverty by making borrowing easier and automating future financial planning, like 401(k) contributions.

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.
