Arrange the energy resources based on their impact on air and water. Place the resource with the greatest environmental impact at the top of the list and the resource with the least impact at the bottom.
Which energy source produces the least pollution overall?
Determine whether each statement is true or false.
Which resource poses the most direct risk to groundwater resources during extraction?
As the global human population continues to grow, so does the demand for energy, food, water, and space. These demands place increasing pressure on Earth's natural systems. When resource use outpaces what ecosystems can replenish, communities risk exceeding Earth's carrying capacity—the limit of what the environment can sustainably support. Which strategy would best help communities avoid exceeding Earth's carrying capacity?
Determine whether each statement is true or false.
As towns and cities grow, energy use increases—powering homes, schools, transportation, and industries. But energy production also affects Earth's systems in different ways. Some impacts become more severe as population size increases. Density-dependent impacts depend on how many people are in a given area. Density-independent impacts might occur regardless of how many people live nearby. Such events can cause major environmental harm whether there are many people nearby or very few. Classify each statement based on whether it is density-dependent or density-independent. Drag each to the correct box.
