caused by natural disasters overfishing and expected climate change

Coral reefs are irreplaceable ecosystems for slot marine life. Protect the coastline and preserve the livelihoods of communities around the world. So you can understand why scientists are concerned about the phenomenon of coral reef erosion around the world. New study indicates reef destruction is faster than previously thought.

A study published in the journal One Earth shows that half of the world's coral reefs have died over the past 70 years. (or more per The "unit of effort") has decreased by 60% since 1950, and coral reefs can only provide half the ecosystem services they did in the 1950s. The result is less biodiversity on the world's coral reefs.

Coral reefs around the world are facing the effects of climate change. overfishing habitat destruction and pollution," the authors write in the study. “With projected coral reef degradation and the associated loss of biodiversity and fishery, well-being and sustainable coastal development of human communities dependent on coral reef ecosystem services, is threatening"

Like a redwood forest Coral reefs are especially heat sensitive ecosystems. Warm water threatens coral reefs by triggering bleaching events. Algae provide nutrients to corals through photosynthesis. But if the algae are exposed to heat stress or too much sunlight. Instead, they will produce toxins. Corals expel algae. bleaching coral Bleaching depends on the severity. can be fatal
