Read the text about pollution. Choose the best option. Pollution occurs when there are many pollutants or dangerous substances in the ecosystem. Pollutants can be from nature, such as gases from volcanic eruptions or forest fires. They may also be the result of human activities, such as garbage or waste from factories. Pollutants have a negative impact on the quality of the air, water and land. There are many human-made products that contribute to pollution. Vehicles like cars, trucks and planes release harmful gases and cause air pollution. The garbage from homes and factories pollutes the land and water. In addition to poisoning vegetation, pesticides also harm animals by flowing into lakes and rivers. When these resources are polluted, all living things in them, from tiny creatures to enormous blue whales, are in danger. Although many people think the countryside is less polluted than the city, pollution can be everywhere. It can spread from urban to remote areas. For example, people can even find chemicals and pesticides in the Antarctic ice sheets. According to the UN Environment Agency, plastic pollution is everywhere and even in isolated locations, such as the Mariana Trench, the deepest part of the Pacific Ocean. What is the main idea of the passage?

Pollution comes from both natural and human sources and can spread everywhere.
