Mention three ways in which you will protect the non renewable resources at an individual level?
Answers
Answer:
Earth has bestowed a bounty of non-renewable resources on humankind, but they won't last forever. The three R's – Reduce, Reuse and Recycle – represent the best strategy for conserving non-renewable oil, coal and natural gas. The United States Environmental Protection Agency champions this approach, which was popularized by environmental conservationists in the late 20th century. Increasing the reliance on renewable energy sources, such as solar, wind and geothermal generators, can also help conserve the dwindling supplies of fossil fuels that remain in the ground.

What are Nonrenewable Resources and How Do We Protect Them?
What are Nonrenewable Resources and How Do We Protect Them?
While the universe is infinitely expanding, the very resources that power the Earth are running out. In 2017, only 11 percent of U.S. energy consumption was generated from renewable energy sources. The rest was powered by nonrenewable resources.
So what are these nonrenewable, or finite, resources, and how can we protect them?
What Are Nonrenewable Resources?
According to the U.S. Energy Information Administration, nonrenewable resources are any resources that “do not form or replenish in a short period of time.” The most common nonrenewable resources include fossil fuels like crude oil, natural gas, and coal, as well as uranium nuclear energy.
Fossil fuels are formed from organic carbon material that has been heated and compressed over millions of years. To put it another way—our most frequently used energy sources like oil and coal are made from the buried remains of plants and animals from millions of years ago.
Earth minerals and metal ores like gold, silver, and iron are sometimes also considered to be nonrenewable resources since they’re similarly formed from geological processes that span millions of years. On the other hand, renewable resources include solar power, wind power, and sustainably harvested timber. They’re renewable because they can be reasonably harvested or created within meaningful timeframes to match demand.
Essentially, a nonrenewable resource is something that can’t be replaced naturally to keep up with human consumption. Because we can’t readily make more oil or coal to use now, nonrenewable resources can also be thought of as finite resources.
Right now, these finite resources are the world’s primary source of power. Thanks to their high energy content, relative affordability, and the current systems in place, our world still runs largely on nonrenewable energy sources.
But this can’t remain true forever. Fossil fuels have adverse environmental effects like climate change—and they’re of a limited quantity. As fossil fuels become more scarce, they’ll become more expensive and less accessible.
The Most Common Nonrenewable Resources
Oil
Crude oil is a fossil fuel that’s used to make gasoline, diesel fuel, jet fuel, heating oil, lubricating oils, and asphalt. This nonrenewable resource is a liquid that’s extracted from underground reservoirs, sedimentary rocks, and tar sands. The crude oil is shipped to refineries where it’s separated into petroleum products.
Natural Gas
Natural gas is obtained by drilling into rock formations that contain natural gas deposits. There are several places natural gas can be obtained:
Conventional natural gas is found in large cracks and spaces in rock formations
Shale gas or unconventional natural gas is found in tiny pores within rocks
Associated natural gas is found in crude oil deposits
When natural gas is withdrawn from its origin, it contains natural gas liquids (NGLs) like ethane, propane, butanes, pentanes, and water vapor. This wet natural gas is sent to processing plants where the NGLs are removed from methane. The methane in natural gas is used in fuel.
Coal
Coal is a sedimentary rock that contains carbon and hydrocarbons. It’s a fossil fuel that takes millions of years to form and contains energy stored by plants. There are four types of coal:
Anthracite has the highest heating value and contains 86-97 percent carbon; it’s used in the metals industry.
Bituminous coal contains 45-86 percent carbon and is the most abundant type of coal found in the United States; it’s used for generating energy and for making iron and steel.
Subbituminous coal contains 35-45 percent carbon and has the lowest heating value among the four types of coal.
Lignite contains 25-35 percent carbon and has the lowest energy content among the four types of goal as well as the highest moisture content; it’s used to generate electricity.
Uranium
Uranium isn’t a fossil fuel, but it’s still considered a common nonrenewable resource. While uranium is a common metal found in rocks, U-235 is a component of uranium that’s very rare. U-235 is extracted from uranium and processed to be used as fuel in nuclear plants for nuclear fission.
