This approach would reduce the amount of plastic thrown away. Very simple strategies, such as turning off the lights when leaving a room and turning off the water when _______ , reduce the amount of energy used.

Reducing the use of _______  is another way to help the environment. These energy sources are called _______  and were formed a very long time ago, when dinosaurs lived on Earth. Burning these fuels releases gases and particulate matter into the air. Many scientists also believe that they contribute to climate change. Driving electric or hybrid cars, for example, can reduce the amount of exhaust from fossil fuels.

Alternative sources of electric energy such as _______ , wind power, and water power help as well. These sources of energy come from resources that do not run out, such as _______ . These types of energy are called renewable energy (Figure 14.18). People can use as much energy as possible from these sources and never run out. Another advantage about this type of energy is that it does not cause pollution. That is why this type of energy is sometimes called _______ . The more people can use renewable energy sources, the more they protect the environment.

Another way of _______  is to take care of your belongings, such as clothes and electronics, so they last longer. Buy used clothes or books instead of new ones. Shop at thrift stores, garage sales, and flea markets to save money and protect the environment at the same time. All of these strategies

Reusing and Recycling

The next best approach to _______  is to reuse and recycle items you use, instead of just throwing them away. Reusing products means they do not have to be thrown away or recycled. For example, instead of using a new plastic bag and throwing it away every time you go shopping, carry a _______ . Buy rechargeable batteries, which you can reuse. When you are done using something, donate it so someone else can use it, too. For example, you could donate clothes you have outgrown to a local homeless shelter, thrift store, or charitable organization.

_______  is a process in which used materials are turned into new products. This reduces the amount of trash sent to _______ . Recycling conserves natural resources and saves energy. Recycling also helps limit the burning of fossil fuels, which contributes to climate change. Many items people use every day are recyclable. For example, newspapers and magazines, _______ , glass bottles, and _______  are all recyclable (Figure 14.19).

Certain types of products need to be _______  in particular ways to protect the environment. These include electronics, such as televisions and computers, and appliances, such as microwaves and _______ . These products can contain dangerous substances. It is important to recycle these products properly so that these substances do not _______ . Many towns have special days these products can be dropped off for recycling. Some stores also collect these products for recycling.

Treatment
The next step in the hierarchy is _______  substances that may be _______ . This approach uses processes that make the substance less dangerous. For example, sewage is treated in _______  plants to avoid the harmful effects of human waste entering the environment.

Disposal
Some products contain _______ , and therefore are not able to be treated or recycled. These products need to be disposed of very carefully to avoid _______  the environment. They cannot simply be placed in a trash can and then dumped in a landfill (Figure 14.20). Most _______  provide specific instructions on how to carefully dispose of these products.

Greener Living
“Green” living means living in a way that protects the _______  It involves limiting or preventing actions that pollute and conserving resources. One goal of _______  is to make choices that create sustainability, or actions that maintain the natural resources in the environment.

When people make responsible choices about using and _______ , they help protect Earth so that these natural resources can last for many, many years (Figure 14.21). For example, _______  is a way of growing plants that reduces any negative impact on the environment. It includes actions such as avoiding the use of chemicals that can pollute the soil and capturing rain to water plants.

Use Less Energy
Making small changes in your behavior can help _______  and conserve natural resources. Following are some simple strategies for using less energy at home:
_______  door as soon as you select what you need.
Use light bulbs that run on _______  (Figure 14.22).

Have a “leftovers night” each week.
When eating out, _______  you do not finish to avoid it being thrown away.

Plant a Tree
_______  is a pretty simple way to protect the environment (Figure 14.24). Trees beautify surroundings and provide shade. The _______  provide can make a home cooler and reduce the demand for air-conditioning. Trees also absorb carbon dioxide and other gases (including _______  and _______ ) from the air, and release oxygen into the air. This helps air quality. Trees also help the environment by holding water in the soil, preventing it from running off.

Be Green Away from Home
There are many ways people can be green at school or work. _______  is one approach. Instead of buying new notebooks, pens, and other supplies each new school year, reuse supplies from the previous year. If buying new items, look for those made from _______ . Office workers can use paper that is no longer needed as note paper.

People can make _______  in the school or workplace cafeteria. Following are some easy ways to make environmentally friendly choices:
If you _______  from home, use reusable containers instead of disposable ones.
Bring drinks in a thermos or safe reusable water bottle.
If you bring cans or bottles to school or work, _______ .
If you buy lunch, take only what you need. Extra napkins and ketchup packages simply add extra waste.
Some schools have a composting program to help reduce the amount of food waste._______  involves gathering food scraps and organic waste into a bin and letting it decompose and then adding it to soil to help plants grow (Figure 14.25). If your school has this type of program, make sure to dispose of your food scraps properly so they are composted and not just thrown away. If your school does not have this type of program, maybe you could work with friends to start one.

Many people do not understand how their choices impact the environment, and how even small changes can help protect the planet.
