Study Notes
Coral Reefs
- Coral reefs make up a small percentage of the ocean floor, but have a significant impact on the ecosystem.
Largest Coral Reef
- The largest coral reef, over 1,200 miles long, is found in Australia.
Economic Impact
- Florida's coral reef is worth millions in tourism every year.
Threats to Coral Reefs
- Coral reefs in areas like the Caribbean are damaged by overfishing and careless anchoring.
- Clean, clear water is essential for coral reefs to thrive, as pollutants and sediments can smother them.
- Pollutants and excess nutrients in the water can cause coral reefs to become diseased, leading to coral bleaching.
Effects of Pollution
- Pollution has a significant impact on coral reefs, causing disease and coral bleaching.
- Pollution from distant places like Mississippi or Mexico can affect reefs in Florida through ocean currents.
Environmental Factors
- Rising water temperatures are primarily responsible for coral bleaching.
Contribution to the Economy
- Coral reefs contribute significantly to the economy of many communities through tourism and fishing.
Overfishing
- One potential consequence of overfishing on coral reef areas is the depletion of key species, leading to an imbalance in the ecosystem.
Individual Actions
- Individuals can contribute to protecting ecosystems like coral reefs by making environmentally conscious choices, such as reducing pollution and supporting sustainable tourism practices.
