A balance between Earth's resources, human needs, and the needs of other species.

the process through which heat is trapped near Earth's surface by substances called "greenhouse gasses".

an introduced species to an environment that becomes overpopulated and harms its new environment.

Explain the influence humans have on the three biogeochemical cycles we discussed in concept 2.

Water cycle- Deforestation affects the transpiration stage. Carbon cycle- Combustion pollutes the air, earth, and water. Nitrogen cycle- Over fertilizing the soil creates a nitrogen imbalance.

List examples of renewable and nonrenewable sources.

Renewable: oxygen, wood, water, sunlight, and wind. Nonrenewable: fossil fuels, metals and plastics.

Summarize the goals of each type of technology, and include one positive and one negative outcome for each.

Agricultural Alternative Industrial

Agricultural: Increase food productivity Pro: Contour farming Con: Pollution

Alternative: Providing clean energy to power society Pro: Decreases burning fossil fuels. Con: Expensive

Industrial: Increase manufacturing, transportation, and communication efficiency Pro: Improves communication Con: Creates harmful CFC's

Describe 3 indirect services the biosphere provides.

-flood protection, -bees making pollen, -natural processes provide drinking water that is safe for human use

Name 2 ways in which eutrophication can be reduced in waterways.

participating in sustainable agricultural practices, reducing pollutants

List three ways humans threaten biodiversity

1) Destroying habitats 2) Pollution 3) Introducing invasive species

Differentiate between direct & indirect economic value of biodiversity

Direct = benefit derived from products provided by biodiversity EX: food, wood, medicines Indirect = benefit that's consistent w/ services derived from biodiversity & of great value 2 society as a whole, not individuals/businesses EX: pollination by bees
