Wise Use Of Our Resources
Pollution
Check for Understanding
Biodiversity is one of Earth’s greatest greatest natural resources. Species of many kinds have provided us with foods , industrial products, and medicines.
Biodiversity is worth preserving because it is valuable to humans.
Altering habitats, extinction, introducing toxic compounds into food webs, and introducing foreign species to a new environment
Biologists are focusing on protecting entire ecosystems as well as a single species. This will ensure that the natural habitats and the interactions of many different species are preserved at the same time.
Transitions Questions
A natural resource any part of the natural environment, created by nature they are considered more valuable considering they are more scarce, they are used by humans for their necessities . For example soil, water, crops, etc.
An unnatural resource is any unnatural environment used and made by humans for their benefits.For example processed foods, plastic, paper, etc. The difference between them is that natural resources are the base of unnatural resources meaning that they are made of them. Natural resources are more valuable too because they are all limited.
Pollution is the act or process of polluting or the state of being polluted, especially the contamination of soil, water, or the atmosphere by the discharge of harmful substances.
Examples: -Garbage
-Toxic Waste
-Gases
The ozone layer is a layer in the earths earths atmosphere that absorbs most of the suns UV radiation. The reason that the Ozone Layer is getting thinner is due to CFCs. This gas goes up into the ozone layer and destroys it by layers.
Nitrogen is bad for the environment because it in excess in our atmosphere. This is due to so much pollution.
The Greenhouse Effect is caused when gases in the atmosphere trap heat, which prevents them from escaping into space. This causes global warming.

What Is Pollution?
Pollution is the contamination of air, water,or earth by harmful or potentially
harmful substances.
Land Pollution
Causes : -degenerative actions
-misuse of land
-land conversion
-soil pollution
-inefficient use of land
Consequences: -animal extinction
-effects on biodiversity
-effects on climate
-biomagnification
Possible Solutions:Some solutions to land pollutions might be to recycle, reusing materials, and also to reduce the use of non-biodegradable materials.

Air Pollution
Causes: -mobile sources
-methane
-smoke
-landfills
-stationary sources
Consequences: -the thinning of the ozone layer
-volcanic eruptions
-wind erosion
-radon expulsion
Possible Solutions:Some solutions to air pollution might be to buy a vehicle that runs solar powered instead of gasoline.

Water Pollution
Causes: -agriculture
-industries
-sanitary wastes
-solid wastes
-natural reasons
-urbanization
Consequences: -human health
-aquatic life
-extinction
Possible Solutions:Some solutions to water pollution might be to dispose of our trash in a proper manner rather than tossing it in a natural body of water.
