How could nonrenewable resources be replaced with renewable resources?
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?
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."
CO2 (Carbon Dioxide) emissions have been on the decline according to the graph. Which answer choice(s) could be a reason for this reduction in emissions?
Blin and Dev are brainstorming ideas to help protect Earth's resources. They know there are decreasing numbers of pollinators for fruit and vegetable plants. These resources are vital to providing us with the food we need to eat. How can Blin and Dev help protect the pollinators we have and increase their numbers?
Which of the following suggestions would help protect Earth's water resources?
True or False: Protecting Earth's resources is very expensive and not practical.
True or False: The foods you eat and the products you buy affect freshwater resources.
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?
Pankaj is presenting helpful tips for protecting Earth's resources to his class tomorrow. He is running through his speech and finds an error with one of the pieces of advice. Which tip is NOT a helpful way to protect Earth's resources?
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?
