Question
Many laws have been passed to protect ecosystems. For example, most wetlands can no longer be filled in. Regulations control how industries can get rid of possible pollutants.
New cars must have devices that reduce air pollution. and before developers can build, they must describe how a project might affect the environment.
But laws alone are not enough. Each person can have a role in protecting ecosystems.
One way is through the conservation, or saving, of resources. Conservation of resources includes three actions: reduce, reuse and recycle.
Reduce means "use fewer resources." For example, if you walk or ride your bike instead of riding in a car, you save gasoline. Opening windows instead of turning on an air conditioner helps reduce the amount of coal burned to produce electricity. Burning gasoline and coal also causes acid rain.
Reuse means "use resources again, instead of throwing them away." For example, you can give outgrown clothes and toys to a charity. That way, someone else can use them.
You can also use glasses and dishes that can be washed and used again and again. That saves plastic and paper that would be thrown away.
Some items can be reused for a new purpose. For example, a plastic drink bottle can be reused as a planter, a bird feeder, or a funnel. Reusing items saves resources and space in landfills, too.
Recycle means "collect used items so their raw materials can be used again." For example, glass, paper, aluminum and some plastics can be ground up or melted and made into new products. And recycling often uses less energy than producing the same items from new resources.
Most glass can be recycled, Recycled glass melts at a lower temperature than the resources used to make new glass. Recycling glass requires 30 percent less energy than making new glass.
Nearly all kinds of paper can be recycled. Making new paper from old paper uses 20 percent less energy than making paper from trees. However, paper coated with wax, foil or plastic is too costly to recycle.
Recycling aluminum helps a lot. Recycling just two cans saves the energy equal to a cup of gasoline. Making a can from recycled aluminum uses only 4 percent of the energy needed to make a can from new resources.
Plastics make up about 10 percent of our waste. Some kinds of plastic are hard to recycle. However, soft-drink bottle are easy. The recycled bottles can be used to make carpeting, boards, new bottles and many other products.
Reducing, reusing and recycling save resources and energy. These actions reduce pollution and help protect ecosystems.
