Transcript of Threats of the World's Coral Reefs

Threats of World's Coral Reefs
Threats of the World's Coral Reefs
About one-fourth of the world's coral reefs are horribly damaged, with a good two-thirds under serious threats.(WWF, 1)

These threats include destructive fishing practices, overfishing, careless tourism, pollution, climate change, sedimentation, and coral mining.
Destructive Fishing Practices
Destructive fishing practices like dynamite fishing not only kill the fish, but also destroy coral reefs as well.
Other very destructive fishing practices include:
Cyanide fishing-spraying chemicals to stun the fish
Bottom trawling-dragging fishing nets along the bottom of coral reefs
Muro-Ami-banging on coral reefs with sticks
Pollution from land is the primary source for the damages done to the reefs.
"Marine debris also affects reefs in many areas. Marine debris is any human-made object that is discarded, disposed of, or abandoned that enters coastal and ocean waters."(NOAA, 2)
As overfishing for like species becomes popular, the food chain is disrupted and could affect all coral reef species.
This includes coral reefs as well.
Farming and construction can cause an influx of sediment in the habitats of the reefs. "This ends up in the ocean, where it can 'smother' corals by depriving them of the light needed to survive."(WWF, 1)
Coral Mining
Coral is mined directly from the reefs and is used for brick, cement, and souvenirs.(WWF, 1)
Careless Tourism

Tourists that like to scuba dive to visit the homes of colorful marine animals cause damage to coral reefs.
People step on the reefs, breaking them and killing the algae that live there.
Climate Change
As the worlds climate change becomes a bigger threat to the entire world, it also threats the reefs.
Since climate change causes water temperatures to rise, it harms the coral reefs since they cannot withstand such high temperatures.

To Conclude...
Coral reefs are facing huge threats towards their populations.
Even though they look like rocks, they are living creatures, and should be taken care of.
Take the protection of Coral Reefs seriously, or soon there will be none left!
