I think that I could reach sustainable living, but it will definitely take a lot of effort.

2. Fossil fuels vs. Renewable energy

Fossil fuels are a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms. Renewable energy is energy from a source that is not depleted when used, such as wind or solar power.

3. Recycle

Recycling is converting (waste) into reusable material.

How long does it take for these to decompose?

a. Tin Can- around 50 years

b. Glass Bottle- 1 million years

c. Disposable Diaper- about 250 to 500 years

d. Wood- 10 to 20 years

e. Paper- 1 to 2 months

f. Plastic Grocery Bag- 1 million years or more

g. Styrofoam Cup- 1 million years or more

h. Aluminum Can- 200 to 500 years

i. Cotton T-shirt- 5 to 6 months

j. Apple Core- 3 to 4 weeks

k. Did any of these surprise me?

No, they all seem reasonable.

4. What is the Great Pacific Garbage Patch? What can we do here in Iowa to help decrease it, is it even possible?

The Great Pacific garbage patch, also described as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific Ocean.

5. Define 2 Biomes of the world, define an ecosystem found in each and explain the Biotic and Abiotic factors involved.

Grassland and Tundra.

grassland - the Savanna Grasslands and the Temperate Grasslands.

tundra - The Artic Tundra and the Alpine Tundra.

6. Choose any Biome; create a food chain defining the primary producer, primary consumer, secondary consumer, tertiary consumer, quaternary consumer, herbivore, omnivore, carnivore, scavenger, and decomposer.

7. What are Dead Zones in the Gulf of Mexico? What causes this situation? What can be done to help stop them?

Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes, caused by "excessive nutrient pollution from human activities coupled with other factors that deplete the oxygen required to support most marine life in bottom and near-bottom water.

8. Define Keystone Species, give 2 examples; one a top predator and one not a top predator. Explain how their absence would affect the ecosystem

a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.

9. Competitive Exclusion- define it and give 2 examples.

  1. the inevitable elimination from a habitat of one of two different species with identical needs for resources.

10. Define the following terms

a. Coexistence- means to live with or close to another usually in peace.

b. Parasites- an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense.

c. Mimicry- the close external resemblance of an animal or plant (or part of one) to another animal, plant, or inanimate object.

d. Mutualism- symbiosis that is beneficial to both organisms involved.

e. Commensalism- an association between two organisms in which one benefits and the other derives neither benefit nor harm.

11. Explain the Carbon Cycle and how do humans affect this cycle?

  1. the series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

12. What is global dimming? Where does it usually affect and why is it a problem?

Global dimming is defined as the decrease in the amounts of solar radiation reaching the surface of the Earth.

13. Explain the Greenhouse Effect. How do the carbon cycle and the greenhouse effect go together?

the greenhouse effect is the trapping of the sun's warmth.

14. Define endangered species and give an example.

a species of animal or plant that is seriously at risk of extinction.

15.Invasive Species- define invasive species; give 2 examples how do they affect the ecosystem they are now invasive too.

An invasive species is a plant, fungus, or animal species that is not native to a specific location.

16. At one time rainforest covered 14% of the Earth’s land surface; today rainforest only cover 6% today; why should a person care about the lost rainforest ground? Why are the rainforest being cut down? What would happen if they all disappeared?

we should stop cutting trees because trees give us air to breathe, and once they are gone we are going to be gone as well.

17.Why is human overpopulation a major concern? Explain all the resources needed for a human to sustain life.

18. Pesticides- what are they, how do they adversely affect the environment, and how does this create problems with the genetic diversity in crop production.

The word "pesticide" is a general term used to describe a substance (or mixture) that kills a pest, or it prevents or reduces the damage a pest may cause. Pests can be insects, mice or other animals, unwanted plants (weeds), fungi, bacteria or viruses.

19. Interpret this quote. “If the bee disappeared off the face of the Earth, man would only have 4 years left to live.” Maurice Maeterlinck, The Life of the Bee

bees pollinate the air, we breath the air, so if bees are gone we only will have so much good air to breath then we would die.

20. It is the year 2070 and you are having a conversation with your grandchildren about how the environment has changed since you were young- give a prediction of how the Earth would look to them.

in 2070, the earth would have cars that float in the air, and there would probably be robots that do everything for you, and a lot of other weird technology and stuff.
