What are the man made factors that affect the biodiversity on the coral reef?

Pollution, overfishing, destructive fishing practices using dynamite or cyanide, collecting live corals for the aquarium market, mining coral for building materials, and a warming climate are some of the many ways that people damage reefs all around the world every day.

What are the environmental factors that affect the biodiversity on the coral reef?

Factors that affect coral reefs include the ocean’s role as a carbon dioxide sink, atmospheric changes, ultraviolet light, ocean acidification, viruses, impacts of dust storms carrying agents to far-flung reefs, pollutants, algal blooms and others.

How does damage to the coral reef impact the biodiversity?

As C02 levels rise and acidification increases, the biodiversity of coral reefs drops, resulting in the elimination of key species needed for healthy reef formation.

How have humans negatively impacted the ability of coral reefs to provide ecosystem services?

Coral reefs worldwide are facing impacts from climate change, overfishing, habitat destruction, and pollution. The cumulative effect of these impacts on global capacity of coral reefs to provide ecosystem services is unknown.

What three factors are identified as major causes of coral reef disease?

The causes of coral disease outbreaks are complex and not well understood, although research suggests that important drivers of coral disease include climate warming, and other anthropogenic stressors such as land-based pollution, sedimentation, overfishing, and human use.

How are humans affecting coral reefs?

Pollution, overfishing, destructive fishing practices using dynamite or cyanide, collecting live corals for the aquarium market, mining coral for building materials, and a warming climate are some of the many ways that people damage reefs all around the world every day.

How do human activities affect species diversity?

How do human activities affect species diversity? Over-exploitation, pollution and habitat conversion are the main threats to species diversity. They cause a gradual loss of species on local, regional and global levels. Additionally, the introduction of species into new ecosystems destroys natural balance.

How does ocean warming affect coral reefs?

Climate change dramatically affects coral reef ecosystems

A warming ocean: causes thermal stress that contributes to coral bleaching and infectious disease. Sea level rise: may lead to increases in sedimentation for reefs located near land-based sources of sediment.

How does coral bleaching impact coral reefs and biodiversity?

Changes in coral communities also affect the species that depend on them, such as the fish and invertebrates that rely on live coral for food, shelter, or recruitment habitat. … Declines in genetic and species diversity may occur when corals die because of bleaching.

How does ocean pollution affect coral reefs?

When sediment and other pollutants enter the water, they smother coral reefs, speed the growth of damaging algae, and lower water quality. Pollution can also make corals more susceptible to disease, impede coral growth and reproduction, and cause changes in food structures on the reef.

What are human impacts?

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

How do humans help coral reefs?

Conserve water. The less water you use, the less runoff and wastewater that will eventually find its way back into the ocean. Volunteer in local beach or reef cleanups. If you don’t live near the coast, get involved in protecting your watershed.

How has human activity impacted the Great Barrier reef?

Human activity has in recent years led to the loss of large sections of Reef and raised serious questions about the strength of its biodiversity and its long-term future. … Meanwhile, sediment reaching the Reef has increased up to 10 times in some areas in the last 150 years, mostly due to grazing and cropping expansion.

What abiotic factors affect coral reefs?

Abiotic Factors

  • Light: Corals need a moderate amount of sunlight in order to survive. …
  • Depth: Reef building corals must live where there are moderate amounts of light. …
  • Water temperature: Remember that corals thrive in the warm waters of the tropics. …
  • Salinity: Salinity is usually measured in parts per thousand (ppt).

What causes damage to coral reefs?

Most coral reefs occur in shallow water near shore. … Coral reefs face many threats from local sources, including: Physical damage or destruction from coastal development, dredging, quarrying, destructive fishing practices and gear, boat anchors and groundings, and recreational misuse (touching or removing corals).

What are some diseases that affect coral reefs?

The most common diseases observed on the Great Barrier Reef include white syndrome, black band and brown band disease. The lethal mechanisms of these diseases are not well understood at present.
