Population and Resources
What effect does an increasing human population have on natural resource consumption?
The more people there are, the more resources we use.
What is a key benefit of using renewable resources like wind or solar energy?
They can be replaced naturally and do not run out.
How does burning fossil fuels contribute to climate change?
It releases carbon dioxide, which traps heat in the atmosphere.
What is one way humans cause habitat destruction?
By clearing land for farming, housing, or roads.
What is one way to prevent invasive species?
Monitoring and controlling imports at borders.
Name three natural resources most affected by population growth.
Water, fossil fuels, and land.
What is one major environmental problem caused by burning fossil fuels?
They release greenhouse gases, which contribute to global warming.
How can climate change make it harder for ecosystems to recover from disasters?
It can increase how often and how bad events like droughts and storms happen.
How are native, introduced, and invasive species different?
Native species belong, introduced species are brought by people, and invasive species spread quickly and cause harm.
How can biological control help manage invasive species?
It introduces natural predators.
What happens when more people need a resource but the supply stays the same?
There is less of that resource available for each person
Why might it be difficult to rely only on solar and wind energy for electricity?
They rely on weather Conditions
Give two examples of actions that can reduce both air pollution and climate change.
Using public transport and switching to renewable energy.
How does large scale farming affect biodiversity?
It reduces the variety of plants and animals in an area.
Why is it important to take action when a new invasive species is discovered?
It can stop the species from spreading and causing more damage.
How does urbanization influence water and land systems?
Cities use more water and land, often causing pollution and loss of nature.
Name one advantage or one disadvantage of using non-renewable resources.
Advantage: They provide reliable energy. Disadvantage: They cause pollution and will eventually run out.
How do wildfires affect air quality and the health of ecosystems?
Wildfires release pollutants into the air and can destroy habitats.
Why is habitat fragmentation a problem for wildlife?
It isolates populations, which makes it harder for animals to find food and mates.
What is the main goal of managing invasive species?
To protect native species and ecosystems.
According to the Malthusian theory, what could happen if population growth outpaces resource growth?
There may not be enough resources for everyone, leading to shortages.
How can using more renewable energy help fight climate change?
It reduces the amount of carbon dioxide released into the atmosphere.
How can air pollution affect human health?
It can cause breathing problems and diseases like asthma.
How can pollution from farms affect rivers and lakes?
Chemicals from farms can wash into water, harming fish and plants.
In what ways can invasive species sometimes be beneficial?
They can help by filling places of extinct species, provide food, habitat, and economic benefit.
