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
