Population Growth
The number of births per 1,000 people
Birth Rate
Pollutants that are released into the air, usually as dark smoke from factories or vehicle exhaust.
Emissions
Anything that we use that occurs naturally in the environment.
Natural Resource
The water and human wastes that are washed down sinks, shower and toilets.
Sewage
The number of individuals that are added to a population over a period of time due to reproduction.
Natality
The study of the size, density, and distribution of the human population.
Demography
The thick brownish haze that hovers over a city. Formed from certain gases and chemicals react with sunlight. It can cause breathing problems and diseases of the eyes and throat.
Smog
The removal of forests to use the land for other reasons
Deforestation
When heat negatively affects bodies of water, it is known as
Thermal Pollution
When the number of humans grows beyond what the available resources can support.
Overpopulation
A growth pattern in which individuals in a population reproduce at a constant rate, so that the larger the population gets, the faster it grows.
Exponential Growth
Dust, Mold, Pet Hair, Glues, Paints, Cleaning Supplies, and Tobacco Smoke.
Allergens
The top layer of soil.
Litter
One of the worst types of water pollution. It can take years to clean up.
Oil Spill
Gases that react in the sunlight to produce a form of oxygen.
Ozone
The Population Growth Rate is calculated as:
(Birth+Immigration) - (Death+Emmigration)
These are two harmful pollutants often found in homes and other buildings.
Carbon Monoxide and Radon
A landfill that has been covered with clay heavy soil.
Capped Landfill
The practice of raising fish and other water-dwelling organisms for food.
Aquaculture
A specific, identifiable pollution source.
Point Source
The maximum population size of a species that an ecosystem can support indefinintely.
Carrying Capacity
The weather condition where normal air circulation is blocked and cool air becomes trapped under a layer of warm air.
Temperature Inversion
The process of restoring land to a more productive state.
Land Reclamation
The process of adding oil consuming bacteria to an oil spill as part of the clean-up effort.
Bioaugmentation
Using a resource in a way that maintains the resource for all future generations.
