USING AND SAVING NATURAL RESOURCES Earth’s Natural Resources Natural resources are found on the Earth and are important to living things. Some natural resources come from below the Earth’s surface. Using Earth’s Resources People, plants, and animals need air to live. Air is a natural resource that never runs out! Water is another natural resource that people and animals use – they drink water in order to survive. Plants also need water to grow. Water is a resource that will never run out thanks to the Earth’s water cycle! Soil is a natural resource that plants need. Plants grow in soil. If plants did not grow, animals would not have anything to eat! Let’s check what we have learned so far: Name one natural resource that plants and animals need. © Copyright NewPath Learning.

Renewable Natural Resources Some natural resources are renewable, which means that they can be replaced if we run out of them. Trees are an example of a renewable resource. If we cut down too many, or if too many die, we can plant more trees! Sunlight, air, and water are also renewable natural resources! These resources will always be available for us, plants, and animals to use. Non-Renewable Resources Some natural resources are nonrenewable, which means that they can NOT be replaced. Coal Coal is nonrenewable natural resource. Coal is burned and releases energy. This energy is used for many things, like for making electricity and heat for our homes and schools. We can dig up coal from the earth, but once the Earth’s supply of coal is gone, it can’t be replaced. It takes millions of years for the Earth to create coal. © Copyright NewPath Learning.

Oil Oil is another nonrenewable natural resource. Oil is made into gasoline, which makes our cars run. We use oil—or petroleum--for many other things. We use it make plastic, and some people use it to heat their homes. Since there are many nonrenewable resources that are important to us, we need use them wisely and carefully. Let’s check what we have learned so far: What does nonrenewable mean? How Can People Protect the Earth? We can use our resources wisely by CONSERVING those important resources. Conserving means to use these resources carefully and to be careful not to waste them. What are some ways we can protect the Earth and CONSERVE natural resources? 1. Do not waste water. You can turn the water off when you are brushing your teeth and you can take shorter showers. 2. Turn out the lights when you leave a room! 3. Do not litter – throw trash away in a trash can, not on the ground! © Copyright NewPath Learning. All Rights Reserved.

4. Do not put bad things in water. Bad things can pollute water. Pollute means to make unclean. Pollution can kill animals. 5. We can reduce the amount of things we use – that means to use less! You can use fewer napkins, tissues, and toilet paper. 6. We can reuse. That means to use something again. Instead of throwing something away, we can reuse it for something else. For example, we can reuse a can as a pencil holder. © Copyright NewPath Learning. All Rights Reserved.

7. Recycle, recycle, recycle! Recycle means to make new things out of old things. Most towns and cities recycle the plastic, cans, bottles, and paper that people use. The used things are put through a machine to make them into something else. For example, they can take your used soda and water bottles and make new carpet out of them! Make sure you recycle things made out of glass, plastic, cans, and paper. Let’s check what we have learned so far: What is one way we can protect the Earth? © Copyright NewPath Learning.
