The modern world that we live in began to take shape. Today human beings are facing some major changes. The world now supports over five billion people. Many of us live very well. We live in houses, drive cars, and wear nice clothes.
Technology makes our lives even easier.
Remember, I m sitting in the backwoods of Africa writing this. Look around at your surroundings. We humans have learned to dominate our environment to the point where nature seems at our disposal. With five billion people on earth, forests are disappearing. Wildlife is dying off, and pollution is a growing problem.
