What are some benefits of recycling .explain how you know

Answer: Incredible Benefits of Recycling

1. Reduce the Size of Landfills

One of the biggest reasons why recycling has been promoted is that it does reduce the strain on our environment. By utilizing waste products in a constructive way, we can slowly decrease the size of our landfills. As the population grows, it will become difficult for the landfills to hold so much and trash. When this happens, our cities and beautiful landscapes will face pollution, poisoning and many health problems. The benefits of recycling are that it helps to keep the pollution in check and decrease it little by little .

2. Conserve Natural Resources

Scrap cars, old bottles, junk mail and used rubber tires are becoming common features of our landfills. All of these may seem endless, but the resources required to make them are finishing off quickly. Recycling allows all of these junk items to be used over and over again so that new resources do not have to be exploited. It conserves natural resources such as water, minerals, coal, oil, gas and timber .

3. More Employment Opportunities

While you may feel that recycling is each person for himself, in reality, it is a huge industry within itself. After you do the basic sorting out and deposit your trash for recycling, it has to be sorted and shipped off to the right places. This is done by thousands of workers, who are newly employed by the growing industry.

Certainly, one of the major benefits of recycling is that it creates more jobs in the community and provides stability to the entire process. Throwing the trash away creates some six to seven jobs at best, where recycling can help create close to thirty jobs.

4. Offers Cash Benefits

Recycling is not all about being charitable and doing what is good for the environment. If it were so, everybody would recycle out of the goodness of their hearts. Most governments have policies in place which give financial benefits to those who recycle. People that take the aluminum cans or glass bottles to the recycling plant get cash benefits in return. In fact, many teenagers can pick up recycling as a way to make extra money on the side. Old newspapers, appliances, plastic, rubber, steel, copper and even beer cans can be sold for money

5. Saves Money

An unexpected place where the benefits of recycling can be seen is our economy. A strong economy is one that is efficient in nature. What drags it down is having to pay for resources that are growing scarce in the country. Every bit of recycling counts when the economy does not have to pay for planting more forests, mining iron ore or purchasing fossil fuels from other countries. When the jobs increase, the economy gets a boost. As the cost of maintaining the current waste disposal system goes down, all the money saved is diverted to where it is needed the most.

6. Reduce Greenhouse Gas Emissions

When you recycle products, you tend to save energy, which results in less greenhouse gas emissions. Greenhouse gases are primarily responsible for an increase in global warming. It helps to reduce air and water pollution by cutting down the number of pollutants that are released into the environment. A recycling rate of 30% can is almost equivalent to removing 30 million cars from the roads.

7.7. Saves Energy

When you recycle aluminum cans, you can save 95% of the energy required to produce those cans from raw materials, energy saved from recycling one glass bottle is enough to light a light bulb for four hours. This clearly shows how much energy can be saved if recycling is taken on a larger scale. With this, the reliance on foreign oil is reduced, which also helps you to save money in the long run.

8. Stimulate the Use of Greener Technologies

With the use of more recycling products, it has pushed people towards greener technologies. The use of renewable energy sources like solar, wind, geothermal is on the rise, which has helped to conserve energy and reduce pollution.

9. Bring Different Groups and Communities Together

At the end of the day, recycling is an act that can bring a community together. Whether it is by picking up trash from the roads or collecting waste materials to raise money for schools and colleges, many simple programs that make a community stronger can be built upon the many benefits of recycling.

Many people have found that their collective efforts in proper waste disposal have made their towns cleaner and happier. Others have found friends and supporters in their mission to change the world. In fact, it is one of the best ways to teach children about responsibility and taking the initiative.

There are 1000 micrometres (um) in a millimetre (mm).
Vesna [10]

Answer: The length of the cell in millimetres is 0.0015.

Explanation:

Given conversion :

1000\mu m=1mm

Thus 1\mu m=\frac{1}{1000}mm=0.001mm

Given : Length of the cell = 1.5 micrometers (\mu m)

To find: Length of the cell in milllimeters (mm)

Length of the cell in milllimeters (mm) = 1.5\times 0.001mm=0.0015mm

The length of the cell in millimetres is 0.0015.
