Coral Reef Informative Speech
I. Attention Getter Coral reefs are the most diverse of all marine ecosystems. They teem with life, with perhaps one quarter of all ocean species depending on reefs for food and shelter.
II. Credibility Statement Coral reefs are also very important to people. The value of coral reefs has been estimated at 30 billion U.S. dollars and perhaps as much as 172 billion U.S. dollars each year, providing food, protection of shorelines, jobs based on tourism, and even medicines (Knowlton, 2015).
III. Relevance Statement Unfortunately, it’s the people that visit these reefs that are the greatest danger to them.
IV. The impact of ecotourism can be reduced by obtaining some sort of awareness and a changing the though process among tourists and locals alike …show more content…
This can also cause an imbalance in the ecosystem. An overgrowth of food can happen because these fish are no longer eating enough of it. This can cause fluctuations in the ecosystem balance, possible causing some reefs to die from over stimulation.
B. People directly interacting with reefs can be detrimental to their health. Either through physical or even chemical means
1. Coral can only grow so fast. From between 2 to 10 cm per year (Knowlton, 2015), depending on the type. People in tourist locations use reefs as surfaces to push themselves off of, most of the time snapping off a few branches under their weight (Tourism's Impacct on the reef, n.d.).
2. Another thing to take into mind is sunscreen. If you’re like me, pasty and white, you’ll use it in abundance in any tropical location. Some sunscreen can be harmful towards creatures and the reef they live in, potentially killing them (Rastogi, 2009).
3. Also, as a side note, it’s not necessary to take thing from the ocean to use as decorative items. Items such as sea stars and fans are part of an ecosystem that doesn’t include our living room. Pretty much 80% of the stuff people take from a reef is something that was previously living. This is essentially killing something and taking away future
