Great Barrier Reef Suffers Worst Coral Bleaching in Its History

Uncategorized By Apr 27, 2023

The Great Barrier Reef, home to over 1,500 species of fish, 600 species of coral and thousands of other marine species and a broad contributor to the Australian economy, has suffered its worst-ever coral bleaching due to climate change. In 2016, two consecutive years of warm sea temperatures led to coral bleaching, affecting over 93% of the reef. The loss of coral could harm the food chain and threaten species, while also causing economic harm to the Australian tourist industry. The Australian government has dedicated more than $1bn to preserve important ecosystems, such as the reef.

Great Barrier Reef Suffers Worst Coral Bleaching in Its History

The Great Barrier Reef, one of the natural wonders of the world, has recently suffered its worst-ever coral bleaching. Coral bleaching occurs when the temperature of the water around the coral rises above a certain threshold, causing the coral to expel the colorful algae that lives inside it. This leaves the coral white and vulnerable to disease, starvation and death.

The Scale of the Problem

The Great Barrier Reef is the largest living structure on Earth, covering an area of more than 344,000 square kilometers. It is home to more than 1,500 species of fish, 600 species of coral and thousands of other marine species. The reef contributes more than $6 billion each year to the Australian economy through tourism, fishing and other industries.

In 2016, the Great Barrier Reef suffered its worst-ever coral bleaching event, affecting more than 93% of the reef. The bleaching was caused by two consecutive years of unusually warm sea temperatures, which were fueled by climate change. The bleaching killed off vast areas of coral, leaving them vulnerable to disease and other threats.

The Consequences

The loss of coral on the Great Barrier Reef has serious implications for the marine ecosystem, as well as for the local economy. Coral reefs provide a home and a source of food for many marine species, including fish and shellfish. They also help to protect coastal areas from storms and erosion.

Without healthy coral, the fish and other creatures that depend on the reef may die or move elsewhere. This could have a ripple effect throughout the food chain, causing further damage to the ecosystem. The loss of the Great Barrier Reef could also have a devastating impact on the tourist industry in Australia, which relies heavily on visitors to the reef.

What Is Being Done?

The Australian government has taken steps to protect the Great Barrier Reef, including implementing a 35-year plan to improve the health of the reef. This plan includes reducing pollution, managing the fishing industry and tackling climate change. The Australian government has also committed more than $1 billion to the reef’s preservation.

Many conservation organizations are also working to protect the reef. These include the Great Barrier Reef Foundation, the Australian Marine Conservation Society and the World Wildlife Fund.

FAQs about Great Barrier Reef Coral Bleaching

What causes coral bleaching?
