Spots of hope: Some good news for South Africa's cheetahs

Invasive weeds are ruining the habitat of New York's wild bog turtles. In Hudson River Valley, domestic goats and cows are being used to save bog turtles by grazing on this foreign weed. So far, the plan seems to be working as the turtles have shown signs of not just returning but also laying eggs in the area.

Growing wolf populations in Wyoming are forcing the U.S. Fish and Wildlife Service to make hard decisions about culling the endangered species in order to preserve local wildlife and livestock.

Concerned with colony collapse syndrome in honey bees worldwide, scientists, farmers and tech companies teamed up in Australia to create a micro-sensor that collects data on the bee's environment.

There are only five northern white rhinos left in existence - all in captivity and unable to breed. Researchers work to identify the most valuable solution to rhino poaching in order to prevent the animal from going extinct.

North America’s protected areas are too small and scattered to sustain wildlife, so conservationists are fighting for Yellowstone to Yukon, a continent-wide network of protected areas which would preserve lifesaving migration routes.

A robust population of grizzly bears can be an indicator of healthy land; however, the bears also can destroy grain bins, consume vegetation, and kill livestock.

The amount of plastic debris in our oceans and water sources - especially nanoplastics that are increasingly prevalent in our food chain - is so enormous it's often beyond comprehension, and immensely difficult to address. As countries continue to industrialize and single-use products become more commonplace, the flow of harmful plastics into the environment seems insurmountable. But a number of clever inventions and dedicated individuals are working to help get plastics out of our water - and more importantly - encourage practices to reduce, reuse, and recycle.

In the Mumbai slum of Dharavi, an NGO called Society for Nutrition, Education & Health Action (SNEHA) is working to make life safer by teaching men the importance of not being violent towards women.
