I. Introduction
A. Background Information

1. Why should we care about coral reefs?
a. Coral reefs offer habitats for million fish and other species.
b. Coral reefs support the significant tourism industry depends on
the clean seawater and amazing coral reefs and fish.

the news writer of States News Service, coral reefs supply about
“$375 billion to the world economy or more $3 billion to Florida
per year from recreation, tourism, food, pharmaceuticals, and
other purposes” (2004, par. 1).


2. Why do the impacts threatening on coral reefs?

a. Anthropogenic disturbances, such as Increasing the tourism industry causes water pollution.
b. Natural disturbances, such as unusual temperature changes that sea-surface continues warming effect the coral life (Kirby, 2004, par. 2).

B. Nature of problems

1. Natural factors effect coral health.
For example, in 2002, the Black water caused some coral reef death in the Florida Keys because it included many “toxic and non-toxic microscopic plants” (Gutro, 2003, par. 1)
2. Human activities threaten coral reefs ecosystem.
For example, boatman drives ship with careless, and diver stands on coral, such as in 1993 to 1994, there were about 500 of ships grounding in the Florida Keys. (Florida Keys National Marine Sanctuary, 2001, par. 10)
3. Coastal developments contaminate coast and seawater, such as increasing tourism industries earn a lot of money and promote local economical growth (States News Service, 2004, par. 1).

II. Thesis: although the local people depend on tourism and food industry for earning money, getting to the bottom of their economic lifeline is from the coral reef ecosystem.

III. Main arguments

1. Local residents should know how important the coral reef ecosystem is.

2. Laws should limit over-development in Florida Keys for protecting coral reefs.

3. Reducing Human activities threaten coral reefs ecosystem, such ship drives through shallow waters along the coast of coral reefs areas, and divers should learn how to avoid harming the coral reefs.

IV. conclusion

A. People should know or learn about coral reefs.

B. People should do something to protect the coral reefs.
