Effects of pesticides

They kill plants/pest.
-Harm ecosystems, can harm humans
-Broad spectrum ones kill more than needed

rodenticides, herbicides, insecticides, fungicides, bactericides

Pyrethrins versus pyrethriods

Pyrethrins are a flower, pyrethroids are man made, both are pesticides.

Pesticide resistance and how to fix it

when a pest builds up an immunity to a chemical so it becomes less effective
Rotating pesticides

GMO

genetically modified organisms- higher productivity, no effects on humans
-we don’t know ALL of the possible affects yet

Pesticide versus Herbicide

Pesticide is a general term, herbicide is one type
-They are both used to keep different pests away

Broad versus Narrow Spectrum Pesticides

Broad spectrum affects anything in an area, Narrow affects just one thing.

Large Scale farming

less manual labor, cheaper, less biodiversity, longer travel of food

Perfectly

Small Scale farming

more manual labor, more expansive, better quality, better options, more natural

Aquifer

flows through rock, beneath the watershed

Perfectly

Where does groundwater come from

the water cycle, precipitation, seeps through the ground in aquifers
-Water is decreasing mainly due to over pumping

Perfectly

Confined Aquifers

Deep underground, harder to get to, cleaner and more filtered water

How well did you know this?

Perfectly

Unconfined Aquifers

Not as deep, easy and less expensive, can get polluted, needs a pump

Perfectly

Surface versus groundwater

Surface water is more city water, has more additives, Kalamazoo uses groundwater with less additives.

Watershed

The main source of water in an area, runoff generally ends up here.

What is polluting the Kalamazoo river?

Hardness (not actually considered a problem though), PCB, arsenic, lead, fertilizers/pesticides

Point source versus non point source pollution

If you can define the exact point that the pollution comes from it is point source.

Where is PBC from?

Paper mills

EPA superfund sites

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

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

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

How will reducing pollution affect economies?

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

Def of global warming

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

What causes global warming?

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

What are some affects of global warming?

biodiversity loss, temperature changes, land shifts

Paris agreement

International agreement to stop pollution Mostly signed by developed countries

Crop line shiffting

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

Who is affected by, and who causes global warming?

Developing countries, developed countries cause most of the pollution

How can we fix Global warming

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

What are the causes of tropical rain forest destruction?

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

Slash and Burn Farming

Cut trees then burn area for planting crops or growing cattle

Why is slash and burn farming "effective"

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

How long can slash and burn farming work?

Only a few cycles

Agroforestry

Form of sustainable agriculture where plants are left in soil

What is the most bio diverse ecosystem on earth

The tropical rainforest

What should be done about rain forest destruction?

Different focus of economy such as eco paper making

What are some sustainable energy forms?

Wind, Hydroelectric, Supplemental, Nuclear, Solar

Nuclear Energy

Using Uranium, isotope 235

What are the best forms of energy

Wind and solar

What are the three types of hydroelectric energy?

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

What is the population Bomb?

exponential growth of population faster than the resources.

Who are three historical figures related to Population bomb?

Thomas Malthus Hans Rosaling Paul Erich

Who wrote the population Bomb

Paul Erich and his wife

Who beilived in 100% child survival?

Hans Rosaling

Who believed that the lower class was responsible, and in survival of the fittest

Thomas Malthas

What is earths carrying capacity

9-10 billion -it is currently 8 billion

What does over population cause?

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

What causes overpopulation?

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

Famine

In dense urban environments diseases spread quicker and people are in a much less clean environment

What are the three biggest fossil fuels and what are they used for?

Coal- electricity Natural gas- factory use Petroleum- transportation

What are the six main air pollutatnts

- Carbon Monoxide - Lead - Nitrous Oxide - Ground Level O-zone - Particulate Matter - Sulfur Dioxide

What are the 4 types of coal

-Anthracite- 107$ -Bituminous- 61$ -Subbituminous- 14$ -Lignite- 20$

Where does Natural gas come from?

Under earths surface

Pros and Cons of natural gas

non renewable, flammable, climate change, methane leaks less CO2, cheaper

What is petroleum?

When processed becomes crude oil, often liquid, found underground

Pros and Cons of Petroleum

Expensive, unsustainable, bad for earth supports jobs, easy to get

What is the most dangerous air pollutant?

Nitrogen Dioxide
