On Sunday, April 22, 1990, people all over the world celebrated the same holiday. It was the twentieth anniversary of Earth Day. The purpose of the holiday, which we celebrate every year on that date, is to help people learn how to protect the planet Earth. People around the world celebrate Earth Day because they worry about the planet. Many forms of animal life are disappearing from the earth. Carelessness and accidents in many countries have caused problems that are harmful to the environment. Air and water pollution, oil spills, and toxic waste are some of the serious problems.
In fact, protecting the earth is truly a worldwide issue. Pollution in one place often affects areas far away. For example, an accident in a nuclear power plant in one country can create a radioactive cloud that goes halfway around the world. Factory smoke in one country can cause acid rain in another. It is easy to see how our protecting the environment has become an international issue.

What Is Insulin-dependent Diabetes
When you eat, your body takes the sugar from food and turns it into fuel.
