Entrepreneurs help rebuild Nepal amid quake recovery delays

Electricity is hard to come by in much of Africa. Now, skipping over the fossil fuel age, solar panels are bringing a cheap form of electricity to the continent.

Officials in Niger are addressing chronic severe droughts causing food shortages and leading to a widespread threat of starvation. They provide aid to malnourished children and resources for a crop planting technique called 're-greening,' which aims to reforest agricultural regions, restore soil quality and, in turn, increase food supply.

Access to electricity in India takes a huge economic, educational, and health-related toll. A small company called Husk Power Systems has created an innovative system that is turning rice husks into electricity and illuminating India’s poorest state.

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.

In order to hunt for the oldest fossils in Africa, scientists needed to produce alternative forms of energy to allow them to live in these desert regions. One such project is the gasifier, which turns discarded doum palm nuts into energy.

Amidst a world struggling with smart ways to confront climate change, Hawaii's 2050 Plan for sustainability is working to be a model for the rest of the world. So far, it is on it's way to being a leader in solar energy, with Honolulu having the most "solar panels per capita than any other North American city," and the state is working to produce more food locally, as well.

The breakdown of the ozone layer is one of the most well-known effects of climate change. Citizens enact different ways to protect the atmosphere from a build up of methane gas.

After a devastating cyclone changed the nature of local soil, NGOs preserved Indian rice crops by reintroducing traditional rice varieties that can be cultivated even in salt-ridden earth. Although some first met this idea with skepticism, many farmers have now adopted the practice after witnessing the success of the crops.

Programs to get fresh produce carts to areas with no access to healthy food work best when government and determined entrepreneurs team up. Success from this model is evident in New York City, where the city has incentivized the selling of fruits and vegetables by street vendors in areas that are in the most need of the produce.

Evidence continues to build that humans are contributing to a climate change issue that is nothing but bad news for the planet. Hopeful stories from seven countries, including India, Indonesia, and China, show that efforts to combat climate change might finally be working.
