The Three Gorges Dam stands 185m high and 3,035m wide. Hydropower projects have had huge impacts on the Yangtze. The dam was designed to beneﬁt people by controlling ﬂoods, generating power and aiding navigation, but it has upset the natural ﬂow of the river.

Humans are land animals. We've sailed the seas for centuries, crossing lakes and oceans and eventually the globe, but we as a species don't need to be out on the water. Sailing persists in part because the sea is an efficient way to transport heavy goods long distances, but cargo ships in the future likely won't need human crews. Rolls Royce, best known for cars but in the general business of engines, thinks autonomous shipping is the way of the future. Today, the company released a paper on “Advanced Autonomous Waterborne Applications”
