The environment is the sum of all external conditions that act upon or influence an organism or community We are a environment and are influenced by it. The environment changes in response to both natural events and human activities. Thunderstorms, floods, vol canic eruptions, and earthquakes are natural processes that affect the environment. Human activities include construction of roads and buildings, farming, and mining uman activities usually change the environment more rapidly and in ways different from natural activities. The human population doubled between the years 1650 and 1850. It is predicted that human population will dou. ble in only 41 years based on the current growth rates. Growth rates vary from country to country, but a million people are added to the world every four or five days 85 million each year. World population is predicted to reach 6 billion by the year 2000. Where will all these people live? What will they eat? This rapidly increasing human population has greatly altered the natural envi- ronment in recent times. Scientists predict even more drastic environmental changes in the future as more peo- ple draw on Earth's limited resources
