The earth is around 4,600 million years old. Modern human beings have lived on the earth for only 35,000 years. But we have changed our planet a lot during that time. We have done something good, but more are bad for our planet.

Air pollution
In big cities, air pollution is mainly caused by factories, cars, trucks and buses. Many people in cities now are in bad health. For example, Mexico city was a beautiful and sunny capital before, but now it is always covered with thick brown clouds.

Dr. Smith is very interested in cleaning water, so he invented a machine called "Living Machine", which can clean waste water in your home or at your workplace.
The "Living Machine" is a system for cleaning waste water. The waste water is dealt with in the machine and the water is brought into a greenhouse filled with plants and fish. With the help of sunlight, the plants and animals remove most chemicals from the water, making it cleaner. Then the water can be reused for washing or bathing. It can't be used for drinking or cooking, but people can use it to water the flowers, wash the dog or swim.
