Major report connects the world's environmental challenges - 2024
Major report connects the world's environmental challenges
Issues like climate chante, biodiversity and water are all interlinked, the report says
Climate change, nature loss and food insecurity are all inextricably linked and dealing with them as separate issues won't work, a major report has warned.
Unsustainable logging, fishing and hunting 'driving extinction' - 2022
One in five people around the world rely on wild animals, plants and fungi for food and livelihoods, according to a landmark assessment.
But many wild species are not being harvested sustainably, putting food security at risk, the report found.
In 2019, experts estimated that one million plants and animals could go extinct in coming decades.
And much of this is being driven by unsustainable fishing, hunting and logging.
Now a new report by the same influential body concludes that the sustainable use of wild species is critical for people and nature.
And climate change and increased demand is likely to push more species to the brink, putting food security at risk.
The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is conservation scientists' equivalent of the IPCC group of climate scientists.
Their most recent assessment, approved by 139 countries in Bonn, Germany, focuses on how fishing, hunting and logging can be carried out more sustainably without damaging biodiversity and food security.
It found that billions of people across the world rely on 50,000 species of wild animals, plants and fungi for food, medicine, fuel, income and other purposes.
The assessment paints a picture of widespread exploitation of nature, with about a third of wild fish in the ocean overfished, more than 10% of wild trees threatened by unsustainable logging, and more than 1,300 mammals pushed to extinction by unsustainable hunting.
Reef in Bermuda. Healthy coral reefs have declined by about 50% in the past 40 years Many of the Caribbean's coral reefs could vanish in the next 20 years, according to a report published by the International Union for the Conservation of Nature (IUCN). Data from more than 35,000 surveys suggests that habitats have declined by more than 50% since the 1970s. The report's authors believe that over-fishing and disease is mainly to blame. They say the trend could continue if nothing is done, but with protection the reefs could bounce back. Carl Gustaf Lundin, director of IUCN's Global Marine and Polar Programme, said the findings were alarming. "The reefs support a number of different countries and populations," he said. "Tourism is one of the biggest industries, and the health of the reef is essential to the well-being of many of the people living there. And of course they are immensely beautiful and wonderful places as well." Reef overrun with algae The reefs are becoming over-run with algae, which suffocates the coral. The report, which was also authored by the Global Coral Reef Monitoring Network, looked at data collected between 1970 and 2012 from 90 reef habitats and is the most comprehensive assessment of corals in this region.
Predators have roamed the planet for 500 million years. The earliest is thought to be some type of simple marine organism, a flatworm maybe or type of crustacean, perhaps a giant shrimp that feasted on ancient trilobites. Much later came the famous predatory dinosaurs such as T. rex, and later still large toothed mammals such as sabre toothed cats or modern wolves. But one or two hundred thousand years ago, the world’s most powerful predator arrived. Us. We lacked big teeth or sharp claws, huge tentacles or venomous bites. But we had intelligence, and the guile to produce tools and artificial weapons. And as we became ever better hunters we started harvesting animals on a great scale. We wiped out the passenger pigeon, the dodo, the great herds of North American bison. Last century we decimated great whale populations. Today the world’s fishing fleets routinely take more fish than scientists say is sustainable, leading to crashes in cod numbers for example, while people kill more large mammals in North America than all other causes put together. But out of our mass consumption of the world’s fauna appears a curious conundrum.
