People and Natural Resources
When more people live on Earth, we need more of these to live.
What are natural resources?
Pollution in the air reduces this ability of ecosystems to recover after damage.What is resilience?
What is resilience?
When water becomes dirty and unsafe to use, it is called this.
What is water pollution?
An animal or plant that naturally lives in a place is called this.
What is a local species?
As this grows, the demand for natural resources like water, land, and energy increases, putting pressure on the environment.
What is the human population?
These resources can be used again and again, like sunlight or wind.
What are renewable resources?
This gas causes the Earth to get warmer and change the climate.
What is carbon dioxide?
When soil is removed by rain or wind, it is called this.
What is soil erosion?
When people bring an animal or plant to a new place, this is called this.
What is species moving?
These types of resources are praised for being clean and sustainable, but can be limited by weather or location, while their counterparts are widely available but polluting and finite.
What are the pros and cons of renewable and nonrenewable resources?
This kind of resource cannot be made again quickly, like oil or coal.
What are nonrenewable resources?
This happens when gases trap heat in Earth’s atmosphere like a blanket.
What is the greenhouse effect?
Cutting down many trees in an area is called this.
What is deforestation?
A new animal or plant that causes problems in a place is called this.
What is a harmful species?
Burning fossil fuels releases pollutants that contribute to this global phenomenon, which can disrupt weather patterns and harm ecosystems.
What is climate change?
Renewable resources are good because they don’t run out, but sometimes they depend on this.
What is the weather?
This air pollutant damages plant leaves and harms ecosystems.
What is ozone?
Chemicals from farms can pollute water and make it unsafe for fish and plants. This is called this.
What is water contamination?
To control harmful species, people sometimes use other animals or plants that eat or fight them.
What is using natural enemies?
This ability of ecosystems to recover from disturbances like pollution and climate shifts is crucial for maintaining biodiversity and ecosystem services.
What is ecosystem resilience?
Using too many resources can cause this problem where nature loses places to live.
What is habitat destruction?
Using cleaner fuel and machines to remove smoke helps reduce this problem.
What is air pollution?
Building and mining can destroy animal and plant homes, causing this.
What is habitat destruction?
Cleaning tools and stopping the movement of animals help with this to protect nature.
What is stopping spread?
Overuse of fertilizers and pesticides in agriculture can pollute these two vital natural systems, affecting both wildlife and humans.
What are water and land systems?
