Population& Resources
What happens to natural resource use as the human population grows?
It increases, putting more pressure on resources.
What is a major cause of air pollution?
Burning fossil fuels (coal, oil, gas).
What is one way humans impact water systems?
Polluting rivers with chemicals or trash.
What is a native species?
A species that naturally lives in an area.
What is one method of harvesting natural resources?
Logging (cutting down trees).
Name one renewable resource and one nonrenewable resource.
Renewable: solar energy. Nonrenewable: coal.
How does air pollution contribute to climate change?
It releases greenhouse gases that trap heat in the atmosphere.
How does farming affect land systems?
it can lead to soil erosion and habitat loss.
What makes a species invasive?
It spreads fast and harms the ecosystem.
Name a low-impact method of harvesting.
Selective logging or sustainable fishing.
What are two pros and two cons of renewable resources?
Pros: sustainable, low pollution. Cons: weather-dependent, costly setup.
What is ecosystem resilience?
An ecosystem's ability to recover from damage or disturbance.
What are some results of land overuse?
Deforestation, desertification, and poor soil health.
Give one example of a harmful invasive species.
Zebra mussels in North America.
How does overharvesting affect biodiversity?
It reduces species numbers and can lead to extinction.
Why can overuse of nonrenewable resources be harmful?
They run out and pollute the environment when used.
How does climate change affect ecosystems?
It changes temperatures, weather patterns, and harms species.
Name a consequence of water pollution on humans and wildlife.
Unsafe drinking water; fish and animals can die.
What is one way to manage invasive species?
What is one way to manage invasive species?
What’s one sustainable farming or fishing method?
Crop rotation or fish farming with limits.
How does population growth affect sustainability?
It increases demand for resources, leading to overuse and waste.
Give two ways to reduce air pollution and how they help ecosystems.
Use clean energy and drive less. This lowers emissions and helps nature thrive.
Explain how urban development changes land and water systems.
It replaces nature with roads and buildings, changing water flow and habitats.
Compare the effects of native, introduced, and invasive species.
Native help balance the ecosystem, introduced may not harm, invasive cause damage.
Suggest one way to promote ecosystem resilience.
Protect natural areas and reduce pollution.
