Plastic, oil and harmful chemicals pollute our land and groundwater. Some wildlife may disappear. What’s more, cutting down too many trees brings sandstorms. Wind can blow soil away.

However, human‑caused pollution becomes serious. Plastic and harmful chemicals hurt groundwater. When we burn oil or gas, it also does harm. Some animals begin to disappear. Cutting down trees makes sandstorms. Strong wind will blow lots of sand away. Luckily, new generations are thinking about useful solutions. Many people visit websites to get more knowledge. We should remember: this is our own planet. We must take care of it, so it can support lives for many years in the future. 根据短文内容,选择最佳答案。 20. What is the main idea of Paragraph 1? A.
