Question

Once there were only a few million people living on Earth and it took a thousand years for that number to double. There are now 3,800 million Earth dwellers and the number double about every thirty-five years. Humans have cleared away forests to make fields for growing crops. They have moved mountains to make room for roads and cities. They have built huge dams across rivers to turn valleys into lakes and they have built dykes to push back the sea and create more dry land to live on. Once everyone cheered at the progress that humans made in changing their environment like this, but now many people are worried by the problems that such changes can bring. When the Aswan Dam was built across the River Nile in Egypt, it was meant to help the farmers by giving them water when they needed it. Unfortunately, people did not realize that much of the nourishing food for plants in the river would be trapped by the dam so the farmlands would suffer. Also, hundreds of kilometers away at the mouth of the River Nile, less fresh water pours into the Mediterranean Sea. This means that the sea will become more salty and fewer fish will be able to live in it. When this happens, people who catch fish for their living will suffer. Problems like this are caused when human look at only one part of environment and do not realize that all environment is bound up together. If one part is changed, other parts may suffer.
