Hotels in Sri Lanka are usually booked out. But many of the accommodations are energy-intensive and environmentally unfriendly. The hotel chain Jetwing is now trying to become carbon neutral by 2020 - largely by using a new type of air conditioning system. It uses biomass instead of electricity.
Humans and animals live in close proximity in the Serengeti national park. The Frankfurt Zoological Society supports locals set up autonomous protected areas on the edges of the park.
The Peruvian city of Cusco is situated 3500 meters above sea level. Until recently, it stank to high heaven. Thanks to modern sewage management, its wastewater treatment facilities are environmentally friendly - and the stench has disappeared.
Commercial fishing fleets are emptying the world's seas. It's an ecological disaster that is also threatening the livelihoods of many small local fishermen. In the Philippines, local residents are fighting to preserve their fishing grounds.
Mobile solar kiosks in Rwanda and other African countries create jobs and protect the environment. People use them to charge their cellphones and batteries or to access the internet.
