Impact On Land Flashcards
Natural resource

Deforestation
The removal of large areas of forests for human purposes.
Urbanization
The development of towns and cities on previously natural areas.
Pollution
The contamination of the environment with substances that are harmful to life
Conservation
The careful use of Earth’s materials to reduce damage to the environment.
Reforestation
A process of planting trees to replace trees that have been cut or burned down
Reclamation
A process in which mined land is restored with soil and replanted with vegetation.
How are some ways the human population has dramatically increased over the last approximately 200 years
Discovery of penicillin; this meant previously deadly illnesses could now be treated and more people survive to adulthood and have children.
- Invention of vaccines; this meant many previously deadly illnesses could now be prevented entirely meaning more people survive to adulthood and have children.
- Invention of indoor plumbing and proper sanitation; this prevented the spread of many diseases such as cholera, dysentery, typhoid, intestinal worms, and polio, causing less people to die.
- Increase in life expectancy; this means people are living longer and therefore using resources for longer.
What are some impacts of deforestation?
Natural habitats are destroyed, decrease of original forests, animals being pushed to the brink of extinction, when that land is used for farming pesticides make the soil quality worsen and changes the biodiversity, and makes a struggle for space.
Pollution and Landfills effects:
As the human population increases, so does the amount of waste we produce. With humans using less and less reusable products and more and more disposable plastics, Landfills have become larger and larger as more waste is sent to them. About 60% of our garbage goes into landfills. Rainwater runoff from these landfills contains chemicals that can pollute the surrounding environment. This pollution can be devastating to many plant and animal species.
basically rainwater runoff contains bad chemicals the pollute enviorment
What can we do to help the environment
Reduce, reuse, recycle, and reforestation
