Many large bodies of water have been developing “garbage patches” in the calm centers of

their waters. One of the largest is the “Great Pacific Garbage Patch” which is twice the size of

Texas. Above is a sample of items found in this patch and how long it would take them to

naturally decompose. Four students are trying to come up with a plan to decrease the amount

of trash finding its way to the patch. Here are their ideas.

1.Sara- We should start banning waxed milk

cartons and switch to plastic

2.Devon- We should burn all of our trash to keep it

from ending up in the ocean

3.Mike- We should stop using aluminum cans and

switch to a new type of container

4.Tina- We should start finding ways to use less

plastic so we throw less away

Which students’ idea would have the greatest positive impact the environment while reducing

the amount of trash going to the ocean?

microscopic plant like organism. The algae that dies is decomposed by bacteria and that

bacteria uses all of the available oxygen in the water. An environmentalist has been sent to

investigate the above river. There have been reports that a small lake at the end of the river is

becoming eutrophic. She has 4 hypotheses about why the lake is being impacted. Which

hypothesis is best supported by the above picture?

• A. The lake would have become eutrophic naturally.

• B. Neither the farm or the factory could cause the eutrophication.

• C. Runoff of fertilizer from the farm is causing the eutrophication.

• D. The factory is dumping chemicals that is affecting the lake down stream.
