Introduction

What is Coral Reefs??Coral reefs are underwater structures made

from calcium carbonate secreted by corals. Corals are ……………………………..live together in groups.

(Coral Reefs)



ImportanceIt is important to realize that reefs are not only

biologically rich and a source of beauty but they also provide many service to the communities they support.

The importance of coral reefs are: Coral reefs are among the oldest ecosystems on

Earth. Coral reefs support a phenomenal diversity of

species and provide irreplaceable sources of food and shelter.



Importance Continue

Coral reef ecosystems support a variety of human needs.

Corals are an integral part of the reef………………….such as mass bleaching and disease.

Upland activities such as deforestation and fertilizer use can smother and kill downstream corals.

Corals have shown remarkable resilience…………giving hope for their continued survival.



Objective

Many coral reefs all over the world are being destroyed. We can all protect the coral reefs by remembering that they are created by a fragile and delicate animal.

The ways that we can save coral reefs:Don’t use chemically enhanced pesticides and fertilizers.

Support organizations that protect coral reefs.

Report dumping or other illegal activities.

Don’t anchor on the reef.



Objective Continue

Respect local guidelines when you visit a reef.

Stay informed.

Volunteer for a reef cleanup.



ResultsImpact of Climate Change on

Coral Reefs

The earth’s climate is changing at a rapid pace. We know global climate………………..including warming seas.

Impact of climate change on coral reefs are:

Increased sea surface temperatures. Rising sea levels. Increased storm frequency and intensity. Altered oceanic currents.



Result Continue

(The decline of the reefs has been rapid: in the 1970s,more than 50% showed live coral cover, compared with 8%in newly completed survey. The scientist who carried it out warned there was no sign of the rate of coral death slowing)

Caribbean coral reefs on the verge of collapse



Result ContinueImpact of Ocean Acidification

(This diagram showing the link between atmospheric carbon dioxide, ocean acidity and the calcification rates of coral reefs and other ecosystems. Insert diagram depicts relationship between atmospheric carbon dioxide (CO2) and ocean carbonate concentrations)



ConclusionNow that we have presented our Coral Reef project to the class, let's review the information we have learned.

We know what coral reefs are.The importance of coral reefs.The ways that we help can save coral reefs.Climate change is some of the many causes of coral reefs destruction.

In conclusion I think coral reefs are very important elements of ocean………………………..and human populations.
