2.2.1 2.2.2Human impacts of the Environment NC 2.2.1 and 2.2.2
Kudzu
Invasive species of plant
Waste lagoons
Large bodies of water that hold waste from pollution or animals
Technology
The application of science
herbicide
substance that kills plants
bioacumulation
substances that build up in tissue over time word sometimes used interchangeably with biological magnification
CH4
Methane (gas made by animals), Important Greenhouse gas
NO2
Nitrogen dioxide released from combustion, one of the causes of acid rain
Invasive species
A non native species that usually takes over an area
Acid Rain
When carbon, nitrogen, or sulfur: dioxides, mix with water in the air Lowers the pH of areas and kills off forests
Alternative energy
Alternative to fossil fuels: wind, water, and solar power. Problem: cost effective, battery use is toxic
Predicted global temperature changes
Average Earth temperature is thought to be increasing.
Fragmentation
Breaking up of a population
Methods of conservation
By law, Restoration, Rewilding, Alternative Energy, Nature Reserves, Recycling
Deforestation
Cutting down trees
ozone depletion
Has NOTHING to do with carbon dioxide, NOR the greenhouse effect, NOR climate change Problem has been solved by no longer using CFCs
Biodiversity
Number of different species in an area
Hog Farms
Pig farms contribute to pollution of methane and nitrogen waste
Biological magnification
When toxins add up over time in a food chain
Erosion
Soil moving from the land, wind or water
SO2
Sulfur dioxide, pollutant, one of the causes of acid rain
Habitat destruction
The place an organism lives is changed
Conservation
To keep safe, to not use too much
Sustainable
To use only what you need so that there are resources for a long period of time
Pollution
Waste being placed in the environment
pesticide resistance
a trait possessed by certain individuals that are exposed to a pesticide and survive
climate change concerns
as the temperature changes on Earth, some places will experience smaller glaciers, longer growing seasons, drought, longer wet seasons.
combustion of fossil fuels
burning of coal and oil releases CO2 and SO2 and can contribute to the greenhouse effect and acid rain
pesticide
chemical that kills bugs or pests in general
How do humans modify their environment?
habitat destruction, resource use, technology helps to reduce the impact, pollution (land, water, air)
global warming
increase in the average temperatures on Earth Now referred to as climate change
Stewardship
responsibility for conserving and restoring the Earth's resources for future generations
