What are the threats to the coral reef environment nowadays?

Coral reefs are dying around the world. Damaging activities include coral mining, pollution (organic and non-organic), overfishing, blast fishing, the digging of canals and access into islands and bays. Other dangers include disease, destructive fishing practices and warming oceans.

Why is biodiversity important in coral reefs?

Biodiversity ensures that some life will continue to survive, even after major catastrophic events that wipe out many species. Biodiverse ecosystems also provide services, for example nursery habitat to edible fish species, which would be difficult and expensive to reproduce artificially.

Why are coral reefs and mangroves important?

Together the coral reef and mangrove ecosystems form a barrier that protects shorelines from the destructive forces of wind, waves and driven debris. These living structures decrease the erosion and physical damage that can often impose significant economic and environmental costs on coastal communities.

Why are coral reefs important and why are they dying?

Since the beginning of the 20th century, sea surface temperatures have increased, and they continue to rise. Not able to cope with the unusually warm temperatures, corals reefs have experienced mass bleaching events at increasingly short intervals. … When corals are without the algae for too long, they die of starvation.

What is the difference between coral and coral reef?

What is the difference between Coral and Reef? Coral is a live animal while reef is a physical structure. Reef is the habitat of the corals, which has been created through the secretions of coral polyps over many generations.

Why are coral reefs often compared to tropical rainforests?

Coral reefs are often called the “tropical rainforests of the sea” for their astounding richness of life. Due to their structural complexity, corals are one of the most productive ecosystems on Earth, providing important services to mankind including fisheries, coastal protection, medicines, recreation, and tourism.

Why is the relationship between the corals and the algae in the coral reefs considered?

The corals and algae have a mutualistic relationship. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return, the algae produce oxygen and help the coral to remove wastes.

How does the third provision protect?

In 1973, the U.S. Congress passed the Endangered Species Act and has amended it several times since. This law is designed to protect plant and animal species in danger of extinction. … The third provision prevents the federal government from carrying out any project that jeopardizes a listed species.

What law protects plant and animal species in danger of extinction who was responsible for passing this law?
