The cargo ship that ran aground off the coast of Mauritius on 25 July, causing incalculable damage, has split in two and its captain has been arrested.
Great Barrier Reef, new photos show the extent of coral bleaching
Nuove foto scattate vicino a Palm Island documentano il fenomeno dello sbiancamento dei coralli che minaccia la sopravvivenza di questo straordinario ecosistema.
Barrier reefs are magnificent constructions, actual living cathedrals built by tiny creatures – the polyps. The greatest example of these natural works of art is Australia’s Great Barrier Reef, which stretches for over 2,400 kilometres reaching a thickness of 150 metres. In just over 30 years, however, the Great Barrier Reef, which is home to thousands of different species, is likely to be reduced to eroding rubble.
Researchers suggest that coral reefs, which evolved throughout different geological eras, won’t survive human-related activities and will be the first ecosystems to go extinct in the modern age. As a matter of fact, corals in the Caribbean have decreased by 80 per cent.
What is coral bleaching
One of the main causes of the accelerating decline of coral reefs is coral bleaching. The first evidence of bleaching has been recorded in the early 1990s and the phenomenon is estimated to intensify in connection with rising temperatures.
When water temperature rises, the symbiotic connection between corals and their dwellers – the zooxanthellae – breaks. Due to an unusual chemical reaction corals send away the zooxanthellae (which give corals their peculiar colour), and start becoming white, stop growing and, therefore, die.
New bleaching on the Great Barrier Reef
The Australian Marine Conservation Society has documented a new bleaching near Palm Island and provided photographic material to UK newspaper The Guardian. According to the National Oceanic and Atmospheric Administration (NOAA), most of the Great Barrier Reef could face yet more severe bleaching in the coming month, as unusually hot temperatures have been registered off Eastern Australia. The Great Barrier Reef Marine Park Authority claimed that water temperature from Cape Tribulation to Townsville was 2 degrees warmer than the average of the period.
Reducing emissions to save barrier reefs
On the basis of NOAA’s predictions, the barrier reef could face higher risks of mortality in the coming month. Great Barrier Reef’s campaign director Imogen Zethoven said that “the 1 billion dollars reef fund announced by the Prime Minister, Malcolm Turnbull, in June last year was a cynical rebadging exercise undercut by its support for fossil fuel initiatives that will spell catastrophe for the reef. It’s immoral that those of us who are making our living from a healthy environment are paying taxes to subsidise infrastructure that’s going to cause climate change in a major way for the next 50 years,” he said. “If this all goes ahead, we’re basically dooming our tourism industry.”
Bangladesh suffered widespread damage as a result of Cyclone Amphan. Yet the Sundarbans mangrove forest acted as a natural barrier protecting the country from further destruction, as it has done countless times before.
A historic win for the Ashaninka of Brazil as they receive compensation for deforestation on their land
On top of a 2.4 million dollar compensation, the indigenous Ashaninka people will receive an official apology from the companies who deforested their lands in the 1980s.
The largest coral reef in the world is severely threatened by climate change, but researchers are developing strategies that could contribute to saving the Great Barrier Reef.
Seychelles have extended its marine protected area, which now covers over 400,000 square kilometres, an area larger than Germany.
The tapir was reintroduced into Brazil’s Atlantic Forest, the country’s most at-risk ecosystem. The species can play a key role in the forest’s recovery.
Forests are home to 80 per cent of the world’s terrestrial biodiversity. This year’s International Day of Forests highlights the urgent changes needed to save them.
Norwegian oil giant Equinor had pulled out of drilling for oil in the Great Australian Bight, one of the country’s most uncontaminated areas. A victory for activists and surfers who are now campaigning for the area to be protected forever.
30 per cent of the planet needs to be protected to stop precipitous species decline. The UN has set out its aims for the the COP15 on biodiversity scheduled for Kunming, China in October.
