Coral Reef Informative Speech

Good day ladies and gentlemen. My name is Crystal. I would like to inform you about some of the threats to our beautiful coral reefs.

Imagine that you were doing some deep sea diving and you happen to swim along this beautiful, interesting and colorful wave of wonder made of stony corals and consist of plants, fish, clear waters, and many other creatures. Coral reefs have often been referred to as the rainforests of the ocean and they are one of the greatest wonders of the ocean.

Coral reefs are underwater ecosystems that are components of a larger ecosystem. Reefs represent one of the most diverse ecosystems in the world. The animals that live on or around the reefs depend on it for food and shelter. There are countless of dangers that threaten coral reefs. Coral reefs have survived thousands of decades of natural change, but many of them may not …show more content…
Pollution from humans are killing coral reefs around the world. Sewage and oil pollution are a few of the pollutions that are poisoning and killing coral reefs. “The net effect of pollution is as bad or maybe worse than the effects of global warming,” said Iglesias, a co-author of the study in the journal Science on how climate change affects reefs (Pollution Killing World's Coral Reefs). Sewage pollution of coral reefs have been recognized as a major environmental problem for many years. Levels of sewage pollution are very high and has caused a variety of sponges, and other species to decline. Releasing sewage into the ecosystems is one of the primary causes of coral reef degradation. Coral reefs ecosystems are extremely sensitive to environmental disturbances. Longer exposure and higher concentrations of oil is killing corals. “Death may not be immediate, but rather take place long after the exposure has ended”(How does an oil spill affect coral reefs, n.d.). Damage to coral reefs are making them collapse. Concern for damaging effects of oil pollution is currently a growing
