Q

Where is PBC from?

A

Paper mills

27
Q

EPA superfund sites

A

a site which the EPA determined contaminated which will then undergo treatment and evaluations

28
Q

What can be done about water pollution in the Kalamazoo river?

A

less small pollution, don’t bury waste, no dams/irrigation systems, plant more, fix piping, monitor hydraulic fracking

29
Q

How will reducing pollution affect economies?

A

Making less cars could bring down car making industries and their workers. Producing safer cars could become a new industry.

30
Q

Def of global warming

A

An increase of the earth’s atmospheric temperature which causes changes in climate
**NOT climate change

31
Q

What causes global warming?

A

Gases trapped inside the atmosphere hold in heat (infrared radiation)
MOSTLY CAUSED BY HUMAN ACTIVITY

32
Q

What are some affects of global warming?

A

biodiversity loss, temperature changes, land shifts

33
Q

Paris agreement

A

International agreement to stop pollution
Mostly signed by developed countries

34
Q

Crop line shiffting

A

When the area in which a certain crop grows climate changes because of global warming

35
Q

Who is affected by, and who causes global warming?

A

Developing countries, developed countries cause most of the pollution

36
Q

How can we fix Global warming

A

Act as soon a s possible, developed nations stop emitting CO2, evacuate island nations

37
Q

What are the causes of tropical rain forest destruction?

A

Jobs such as cattle ranching, logging, and farming and overpopulation

38
Q

Slash and Burn Farming

A

Cut trees then burn area for planting crops or growing cattle

39
Q

Why is slash and burn farming “effective”

A

It causes the nutrients to go back into the poor soil and creates space to farm/ranch.

40
Q

How long can slash and burn farming work?

A

Only a few cycles

41
Q

Agroforestry

A

Form of sustainable agriculture where plants are left in soil

42
Q

What is the most bio diverse ecosystem on earth

A

The tropical rainforest

43
Q

What should be done about rain forest destruction?

A

Different focus of economy such as eco paper making

44
Q

What are some sustainable energy forms?

A

Wind, Hydroelectric, Supplemental, Nuclear, Solar

45
Q

Nuclear Energy

A

Using Uranium, isotope 235

46
Q

What are the best forms of energy

A

Wind and solar

47
Q

What are the three types of hydroelectric energy?

A

Impound- Dams
Diversion- natural water patterns
Pump Storage facility- open-close-loop

48
Q

What is the population Bomb?

A

exponential growth of population faster than the resources.

49
Q

Who are three historical figures related to Population bomb?

Q

What is earths carrying capacity

A

9-10 billion

Q

What does over population cause?

A

global warming, pollution, habitat loss, possible 6th mass extinction, resource loss

Q

What causes overpopulation?

A

global warming, pollution, habitat loss, possible 6th mass extinction, resource loss

56
Q

Famine

A
