Question

A
Evidence:
Provide two pieces of evidence from the scenario.





Reasoning:
Explain how the evidence supports your claim about environmental impacts.





Scenario 5: Electronic Waste from Technology Upgrades

A city experiences rapid technological growth, and residents frequently replace their smartphones, laptops, and tablets with newer models. Many of the old electronic devices are thrown away and end up in landfills. Electronics contain materials such as metals, plastics, and small amounts of chemicals that can slowly leak into the soil and groundwater as the devices break down. Environmental scientists studying landfill sites are investigating how this growing amount of electronic waste may impact nearby ecosystems and water sources.

Question:
What argument could you make about the ecological effects of electronic waste?

Claim:
Write your argument about the environmental impact of e-waste.





Evidence:
Use two pieces of evidence from the scenario.





Reasoning:
Explain how the evidence supports your claim and why these matters for ecosystems.





Scenario 6: Industrial Shipping and Ocean Ecosystems

Global trade has increased dramatically due to improvements in transportation technology. Large cargo ships now transport products across oceans every day. While this system allows goods to reach markets around the world quickly, it also requires large amounts of fuel. Scientists have found that fuel emissions from ships contribute to air pollution, and accidental oil leaks can sometimes occur in marine environments. Marine biologists are studying how increased shipping traffic might affect ocean ecosystems, including fish populations and coral reefs.

Question:
What claim can you make about the environmental impact of industrial shipping?



Claim:
State your argument about shipping and ocean ecosystems.





Evidence:
Provide two pieces of evidence from the scenario.





Reasoning:
Explain how the evidence supports your claim about marine ecosystems.







Scenario 7: Agricultural Monoculture

To increase efficiency, many farms begin planting large fields with only one crop, such as corn or soybeans. This practice, known as monoculture, allows farmers to use specialized equipment and produce large harvests. However, scientists studying these fields notice that there are fewer types of insects, birds, and plants in the area compared to farms that grow a variety of crops. Researchers are investigating how reduced biodiversity in these environments might affect the stability of the ecosystem over time.

Question:
What argument can you make about how monoculture farming affects biodiversity?

Claim:
Write your argument.



Evidence:
Provide two pieces of evidence from the scenario.





Reasoning:
Explain how the evidence supports your claim about biodiversity and ecosystem stability.







Scenario 8: Medical Advances and Population Growth

Medical innovations such as vaccines, antibiotics, and improved healthcare have helped people live longer and healthier lives. As a result, the global human population has increased significantly over the past century. With more people needing food, water, housing, and energy, more land is being developed for farms, cities, and infrastructure. Forests and natural habitats in some areas are being cleared to make room for these developments. Environmental scientists are studying how increased human demand for resources may affect ecosystems and biodiversity around the world.

Question:
What claim can you make about how medical advancements can indirectly impact ecosystems?

Claim:
State your argument.





Evidence:
Provide two pieces of evidence from the scenario.





Reasoning:
Explain how the evidence supports your claim and connects it to human impacts on ecosystems.

Answer 1

Scenario 5: Electronic Waste from Technology Upgrades

Claim:
E-waste from frequent device replacement is likely contaminating soil and groundwater and harming nearby ecosystems and water sources.

Evidence:
1. Residents frequently replace smartphones, laptops, and tablets and many old devices are thrown away and end up in landfills.
2. Electronics contain metals, plastics, and small amounts of chemicals that can slowly leak into the soil and groundwater as the devices break down.

Reasoning:
Because large numbers of devices are accumulating in landfills, the total quantity of metals and toxic chemicals entering the environment increases. As those materials leach into soil and groundwater, they can poison plants, microbes, and animals, reduce water quality for downstream organisms and humans, and bioaccumulate up food webs. Over time this contamination can degrade habitat quality and disrupt ecosystem functioning.

Scenario 6: Industrial Shipping and Ocean Ecosystems

Claim:
Increased industrial shipping is harming ocean ecosystems through pollution and greater risk of oil contamination, which can damage fish populations and coral reefs.

Evidence:
1. Fuel emissions from ships contribute to air pollution.
2. Accidental oil leaks can sometimes occur in marine environments, and shipping traffic has increased dramatically.

Reasoning:
Higher emissions contribute to air- and water-quality changes (including deposition of pollutants and climate-related effects) that stress marine life. More frequent and heavier shipping raises the chance of spills and chronic pollution; oil coats organisms, smothers corals, and reduces survival and reproductive success in fish and invertebrates. Together, these effects can reduce biodiversity, damage reef systems, and alter food webs.

Scenario 7: Agricultural Monoculture

Claim:
Monoculture farming reduces biodiversity and makes agricultural landscapes less stable and resilient.

Evidence:
1. Many farms plant large fields with only one crop (monoculture).
2. Scientists observe fewer types of insects, birds, and plants in those areas compared to farms that grow a variety of crops.

Reasoning:
Single-crop fields provide limited habitat and food diversity, so fewer species can persist. Reduced species diversity weakens ecosystem services (pollination, natural pest control, nutrient cycling) and increases vulnerability to pests, diseases, and environmental change. As a result, monoculture systems are less stable and more likely to suffer large productivity losses when stressed.

Scenario 8: Medical Advances and Population Growth

Claim:
Medical advances that boost human survival indirectly drive habitat loss and biodiversity decline by increasing demand for land and resources.

Evidence:
1. Medical innovations (vaccines, antibiotics, improved healthcare) have helped people live longer and led to significant global population increase.
2. With more people needing food, water, housing, and energy, more land is being developed for farms, cities, and infrastructure; forests and natural habitats are being cleared in some areas.

Reasoning:
A larger human population raises demand for resources, prompting conversion of natural habitats into agriculture and urban areas. Habitat loss and fragmentation remove species’ homes, reduce population sizes and genetic diversity, and disrupt ecosystem processes. Over time this leads to declines in biodiversity and the ecosystem services (clean water, pollination, climate regulation) on which people and wildlife depend.
