what is sustainiable living? How could someone acheive this? * Do you think that you could personally acheive this?

1. Sustainable living is a lifestyle that attempts to reduce an individual or society's use of the earths natural and personal resources. *there are many things you can do to achieve this, but some are, make sure your big purchases have big benefits, ditch plastics, make others aware of the dangers of products that hurt wildlife and the environment, "green" your house, use renewable products. * i personally think that i couldn't fully live like this, i could do some things in my house but not at all.

2. fossil fuels vs renuwable energy-compare and contrast the two forms-look at the financial costs- convince someone to conserve energy.

Advantage: the current power generation and distribution model operates on fossil fuels, and has for centuries if you consider coal. Fossil fuel essentially is portable energy, if we don't have this, we don't have much of other things. An advantage of renewable energy is it doesn't run out and it comes naturally. Disadvantage: a weakness of fossil fuels is its chemical makeup, a weakness of renewable resources is the harness or replicate nature’s processes in its production. Fossil fuels is losing costs, also the costs of producing electricity from renewable resources has dropped a lot over the past 5 years narrowing the gap with power generated with fossil fuels. Saving energy leads to saving money because the less energy they use the less they have to pay. By shutting off lights that you aren't using in your home you will be saving so much. In the summer if you can walk from place to place that will help save energy and you will get exercise in at the same time. Walking and not using your car will save money too and help stop global warming also.

What does it mean to recycle? Why should someone recycle? how long does it take for these to compose:

Convert (waste) into renewable resources. Recycling has numerous benefits to the environment like saving energy, conserves natural resources, limits pollution, and supports many sectors of the economy.

how long does it take for these to compose?

a. tin can- 50 years

b. glass bottle- 1,000,000

c.disposable diaper-550

d. wood-1 year

e. paper- 1 month

f. plastic bag-500-1,000

g. styrofoam cup- 1plus million years

h. aluminum can-200

i. cotton T-shirt- 1-5 months

j. apple core- 2 months

k. did any of these surprise you? yes a lot of these surprised me because i just figured that all these would only take up to abut 1 year but it actually goes up to like 1,000,000 plus years!

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

Another name for it is the Great Pacific trash vortex. It is where all trash goes to one spot. The only thing here in Iowa that we can do is if we every go over to that area, throw your trash where it belongs.

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

Grasslands and tundra

grasslands hold an ecosystem for many past and present organisms

tundra mammals, birds and insects

Biotic= of, relating to or resulting from living things

abiotic= physical rather than biological, not from any living organism.

6. Choose a biome and create a food chain

The Tundra is my biome.

the location is in the northern hemisphere

the food chain=

lichen, moss, grasses- producers

arctic hare, lemming, caribou, musk ox and pika- consumers

arctic wolf- secondary consumer

brown bear-tertairy consumer

polar bear- tertiary consumer

7. What are dead zones in the gulf of mexico? what causes this? what can be done to help stop this?

also known as hypoxic zones are areas in the ocean with low oxygen concentration levels, when animals go down there they suffocate. The low amount of oxygen causes this and also caused by excessive nutrient pollution from humans.

We can help stop it by fixing the problem with runoff in to the lakes and oceans, put laws into effect form fertilizers and waste runoff

and build water treatment plants to prevent human and animal waste from entering the waters.

8. define keystone species. give two examples, one a top predator and one not. and explain how their absence would effect the ecosystem

a species that has a disproportionately large effect of its environment relative to its abundance.

otters and sea urchins are two examples

otters help eat away the forest of kelp in the waters, and without them there would be a hung amount of kelp in the waters and nobody to take care of it besides humans.

without sea urchins the coral reefs would be unprotected at night and it wouldn't be taken care of properly with out them.

also sea otters feed on these urchins and without the otters to eat some of these urchins the urchins would eat all of the sea weed and kelp and there would be hardly any left

9. What is competitive exclusion and give 2 examples of it

Competitive exclusion- the inevitable elimination from a habitat of one of two different species with identical needs for resources

birds and pack of wolves are two examples.

10. define each term and give 2 examples of each

coexistence is the state or condition of living in harmony- birds and horses and horses and turtles

parasites is living in or on someone or something- living on whales and living in human stomaches

mimicry is the action or art of imitation someone for entertainment-

mutualism is the way two organisms of different species live- a fish and a donkey each live completely different lives

commensalism is a class of relationships between two organisms where one benefits from the other without effecting it.- a little animal in a crocodiles mouth cleaning its teeth, the croc benefits and the small animal doesn't die

11. Explain the carbon cycle and how humans affect it

the carbon cycle is the biogeochemical by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the earth. Humans affect this when a surplus of fossil fuels is burned and large amount of carbon is released into the air. Deforestation reduces the amount of vegetation that can reduce the atmosphere's carbon levels and creates less habitable soil for new growth

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

global dimming is the decrease in the amounts of solar radiation reaching the surface of the earth.

sense the 1950's the places it has happened the most is in Antarctica by 9% in the U.S.A 16% and in Europe by 22%, all of these causes a huge risk for our environment.

global dimming is a major problem to all living beings because it can cause acid rain and smog. Many other things can happen because of this also

13. explain the greenhouse effect and how to the carbon cycle and greenhouse effect work together?

the greenhouse is the trapping of the suns warmth in a planets lower atmosphere due to the greater transparency to visible radiation from the sun than to in fared radiation to the earths surface.

The carbon cycle and the greenhouse effect work together because carbon is a building block of life and a form of stored energy. When fossil fuels are burned for energy/ combustion, carbon is released. Carbon compounds move through plants and animals, the air, the ocean, and the each. Carbon present in the air as carbon dioxide and contributes to the greenhouse affect a related to global warming.

14. define endangered species and give an example. How do species become endangered? what if it was a keystone species? What would happen to the ecosystem? and why should humans care about endangered species?

endangered species: a species that has been categorized by the international union for conservation of nature, because they are at risk for extinction. an example is a white tiger

species become endangered by the environment, humans and a lack of food sources or reproduction. If a keystone species would become extinct or endangered the IUCN would help protect them with all ways possible. If a keystone species would be extinct the ecosystem would take a part in falling apart also. it would take more work for humans to take care of the ecosystem because the animal is now gone. We should take care of endangered species because once they are gone, they are gone forever and they can come back

15. define invasive species. how do they effect the ecosystem and how did they get there?

invasive species: an animal, plant or fungus that is not native to any certain location

examples: frogs, zebra muscles, lion fish

with the example of zebra muscles they effect the lakes and oceans by taking over and effect everything around them. it is impossible to make them go away but there are ways to help stop the spread of then. They get transported by boats and not cleaning out the lake water from pervious lakes when you enter another

16. why should people take care of the lost rainforest ground? why are they being cut down? what would happen if they completely disappeared?

we need to take care of the lost ground because someday more trees could grow, animals still live around there and we shouldn't be taking over that ground. They are cutting down these grounds because they want wood for fires, land for farms, land for poor farmers who don't have anywhere else to live, grazing land for cattle, pulp for making paper, road construction and extraction of minerals and energy.

17. why is human overpopulation a major problem? explain all resources for humans to sustain life

the earth can only produce a certain amount of water and food. because there isn't a numerous amount of resources for every country war outbreak occurs

18. pesticides- what are they? how do they effect the environment? and how does it effect crops?

pesticides- a substance used for destroying bugs or other organisms harmful to cultivating plants or to animals.

they can be carried out of where you are spraying them through the wind, rain and animals. when you don't deal with them correctly they can be a poison to humans , animals and the environment. they mess up food chains also.

if it gets into the crops even after you boil your food you are still at risk

19. interpret this quote

"if the bee disappeared off the face of the earth, man would only have 4 years left to live."With out the bee we would have pollination and with out that we wouldn't have food because 1/3 of our food has to be pollinated by insects for them the grow, so we would die after 4 years

20. it is 2070 and you are talking to your grandchildren and you are telling them how much the environment has changed, make a prediction

i predict that the would will look completely different with all the new inventions and gadgets. The environment will look strange to me but not to my grandchildren. there could be underwater rooms and underwater passage ways to get from place to place without the problem with road construction, you would have multiple ways from getting place to place
