This interesting book shows how the use of this “clean” form of energy, called hydroelectricity, is being expanded to help us build a more sustainable future. Discover how other forms of water-based energy, such as energy from ocean waves and tides, are being harnessed and used to help create electricity to power our homes, offices, and factories.
For nearly two decades, Dian Fossey immersed herself in the study of mountain gorillas in Africa. She became known as a highly respected primatologist - a scientist who studies apes and other primates - and a fiercely devoted champion of their safety and preservation.

In 1985, she was found murdered in her cabin in Rwanda. The case remains unsolved to this day, but her intense love for this endangered species helped create a legacy that survives in the work of others to this day.
