hydroelectric dams



PROS: Clean alternative power source. Safer than altnerative options like nuclear power. It can store rain water directly from the river itself. Controls flooding and provides recreational activites (boating, swimming, fishing, ect.)



CONS: You must gloof a huge area of land for the dam to work. They are expensive to build. Disrupts natural seasonal changes in the river, and ecosystems can be destroyed.

  1. Bill Gates and Steve Jobs have changed Computer history completely. But the interesting part is who is known as father of computers- Charles Baggage did not know that he would make an important place in history with his invention. Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Simple computers are small enough to fit into mobile device, and mobile computer can be powered by small batteries. Personal computers in their various forms are icon of the Information Age and are what most people think of as "computers". It was a great invention of world history.
