Avoid causing physical damage to reefs with boat anchors, or by trampling or touching reefs while diving or snorkeling. Reduce household waste, including chemicals and fertilizers, that reach waterways. Support local conservation efforts and participate in planning and development decisions that affect reefs.

What are the economic impacts of coral bleaching?

Degradation of these reefs costs dearly through loss of fishing livelihoods, protein defi- ciencies and the increased potential for malnutrition, loss of tourism revenue, increased coastal erosion, and the need for investment to stabilize the shoreline.

How does coral bleaching impact the environment?

Bleaching leaves corals vulnerable to disease, stunts their growth, affects their reproduction, and can impact other species that depend on the coral communities. Severe bleaching kills them. The average temperature of tropical oceans has increased by 0.1˚ C over the past century.

What are the negative effects of coral bleaching?

Bleached corals are likely to have reduced growth rates, decreased reproductive capacity, increased susceptibility to diseases and elevated mortality rates. Changes in coral community composition can occur when more susceptible species are killed by bleaching events.

What would happen without coral reefs?

Coastlines would take a battering Without them, shorelines would be vulnerable to erosion and rising sea levels would push coast-dwelling communities out of their homes. Nearly 200 million people rely on coral reefs to safeguard them from storms.

Why are coral reefs fragile ecosystems?

Despite their many strengths, coral reefs are fragile. These habitats are experiencing significant stress and decline as a result of human activity, rising water temperatures, increasing seawater acidity and pollution.

What role does coral play in the ecosystem?

Providing shelter and spawning grounds to a wide range of ocean life, coral reefs serve an important role in the marine ecosystem. Another role is protection from strong ocean currents and high waves. As the name “barrier reef” implies, reefs act as a barrier protecting the shorelines.

Why are coral reefs so productive?

Coral reefs are among the most productive ecosystems on the planet, with the primary producers at the base of the food chain (including corals) supporting their complex food webs. Although light provides the energy that fuels reef productivity, key nutrients such as nitrogen and phosphorus are also required.
