How could nonrenewable resources be replaced with renewable resources?
How could nonrenewable resources be replaced with renewable resources?
Tap to reveal answer
Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods. Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Creating electricity with solar energy instead of coal will reduce the dependence on fossil fuels, find a cleaner way to produce electricity, and reserve more coal.

Jinger was researching water sources on Earth and learned that only 3% of Earth's water is freshwater. She also read that this resource is becoming polluted in a significant way. Which answer choice(s) demonstrates a rational solution to the water pollution problem?

Jinger is very proactive in thinking of ways that she can reduce her impact on our freshwater resources. With only 3% of the Earth providing necessary freshwater supplies, humans cannot afford to waste or poison the water. Keep litter, pet wastes, leaves, and debris out of street gutters and storm drains to keep sewer systems from being overwhelmed with materials that need to be sorted and cleaned. Disposing of used oil, antifreeze, paints, and other household chemicals properly are essential for lakes and ponds in nearby areas. Water run-off from hosing these materials out of driveways or flushing them down storm drains leads to absorption and spread. Applying lawn and garden chemicals sparingly and according to directions will help to reduce waste and overuse of harmful chemicals that leak into water sources.

The United States Environmental Protection Agency released a report of the different sources of energy and how much of each was consumed between 1949 and 2017. The EPA reported that:
"From 1949 to 2017, total U.S. energy use roughly tripled. Energy use has risen fairly steadily over time, with the exception of a few noticeable declines in the 1970s, 1980s, and late 2000s, which were largely associated with supply shocks (e.g., the 1973 oil embargo) or economic downturn. In 1949, the U.S. obtained 91 percent of its energy from fossil fuels. Despite the emergence of nuclear power and the growth of renewable sources, in 2017, the nation still relied on fossil fuels for 80 percent of its energy needs. For that year, the largest share (37 percent) of U.S. energy consumed was derived from petroleum (including gasoline), followed by natural gas (29 percent) and coal (14 percent). Recent years have seen increases in some sources of energy (natural gas and renewables) and decreases in others (petroleum and coal)."
Burning coal, oil, and gasoline give off sulfur, nitrogen, and carbon into the air. These emissions combine with water vapor in the clouds and make acid – sulfuric, nitric, and carbonic acid. The wind carries acidic clouds, sometimes thousands of miles. They fall to Earth as acid rain or snow. How can the effects of these emissions be decreased?

Energy consumption and the sources used to feed this every growing need are a constant battle and concern in the United States. Reliance on renewable resources would limit the use of petroleum, natural gas, and coal, which are nonrenewable fossil fuels. These resources take millions of years to replenish, and our supply is slowly running out. Renewable resources like hydroelectric power, solar power, and wind power are all options that are a financial investment to start but cost less over time, have a dramatically less negative impact on the Earth, and do not run out. The idea to increase the reliance on renewable sources and decrease the dependence on nonrenewable sources is a scientifically based idea that is reasonable and may work. Using electricity derived from wind, water, or solar power will be beneficial to decreasing emissions.

Blin and Dev are highlighting a significant problem around the world - the reduction of pollinators. These are one of Earth's vital resources because they help plants reproduce and make the fruits and vegetables we consume daily. Pollinators can be birds, bats, bees, butterflies, and many other creatures. They spread pollen from one plant to another, allowing the plant to become fertilized. Planting flowers that bloom in a variety of colors will attract different pollinators to the different colored color petals. This will increase the likelihood of plants being fertilized and reproduction occurring.

The Environmental Protection Agency issues reports on many factors that impact the Earth's environment. The following graph highlights the area of growth in the United States and our emissions. The EPA explains the graph's data, "Between 1970 and 2018, the combined emissions of the six common pollutants (PM2.5 and PM10, SO2, NOx, VOCs, CO, and Pb) dropped by 74 percent. This progress occurred while the U.S. economy continued to grow, Americans drove more miles, and population and energy use increased."

Clean air is essential for all citizens of the United States, and according to the EPA, many of our emissions have decreased in recent years, but there is still room for improvement. Hybrid vehicles and electric vehicles have come down in price, making them more affordable for the everyday driver. This new access to an alternative full vehicle reduces the emissions produced. Many cities are improving their public transit infrastructures allowing residents to use busses, trains, and high-speed rail systems to travel. This reduces the number of individual drivers on the roads, so there are fewer emissions.

When it comes to fishing, many states have limits on the number of fish or the size of fish that you can keep. For example, in Florida, there is a limit on one 18 inch Bonefish catch per person per day. Why would states put this limit in place?

All of the answer choices are correct and are scientific-based solutions to protect natural resources. Having fishing seasons, size limits, and catch limits helps to protect endangered and threatened species of fish, allow them to reach maturity so they can reproduce, conserve the populations of fish we have, and enable reproduction rates to catch up with consumption rates. These rules put in place help to protect Earth's resources.
