Read the text. Then choose the correct answer for each question below. In prehistoric times, people killed animals for food. They built fires to cook food and keep warm. They cut down trees for fuel. Their fires released smoke into the air. But there were so few people that their activities had little impact on the environment. In modern times, the world's population has grown quickly. In 1850 there were about one billion people on Earth. By 2005 there were about 6.4 billion in the world. By 2050, according to United Nations estimates, there will be 8.9 billion people. Today we have a big impact on the environment. People can seriously harm the planet and its animals and plants. Sometimes this damage can be reversed or slowed down. But it is often permanent. Every April 22, the world celebrates Earth Day. This helps make people more aware of environmental problems and ways they can help.
