[QA] What is unsustainable harvesting?

Unstainable harvesting is overexploitation. It’s overharvesting a resource to the point where it can no longer replenish the population level in a natural manner.⁠

Unsustainable harvesting, including hunting, trapping, fishing, and logging is one of the biggest threats to biodiversity (one of the primary five threats). In a new article published in the journal Science Advances, a team of scientists identified regions under high-intensity threat from the commercial harvesting of species. On land, these high-risk regions occur across all continents but are especially concentrated in Asia and North & South America. At sea, these regions are particularly concentrated in Asian seas. ⁠

Dr. Enrico Di Minin the lead author highlighted that urgent actions are needed in the centres of unsustainable harvesting to ensure that use of species is sustainable.⁠

“We found that high-risk areas contain 82% of all species impacted by unsustainable harvesting, and more than 80% of the ranges of Critically Endangered species threatened by this threat. Currently, only 16% of these regions are covered by protected areas on land and just 6% at sea. Furthermore, species threatened by unsustainable harvesting are especially concentrated in areas where governance is the lowest”.⁠

The report noted that “unsustainable harvesting is now the most prevalent threat affecting threatened marine species and is the second most prevalent (after agriculture/aquaculture) for terrestrial and freshwater species.”
