Thanks to the 1999 Environment Protection and Biodiversity Conservation Act, 26 endangered species in Australia have seen their populations recover.

It seems like that we're always hearing about new animals that have become endangered, but there's some good news in Australia: 26 animal species no longer meet the criteria to be listed as threatened. Australia’s biodiversity has been in decline, with more than 1, 700 species and ecological communities known to be on the line. In 1999, the Environment Protection and Biodiversity Conservation (EPBC) Act was passed to introduce protections for endangered animals. The burrowing bettong is one of 26 Australian species that have returned from the edge of extinction.

Seemingly these are working, as a recent study published in the journal Biological Conservation reviewed the animals that were previously or currently listed as threatened between 2000 and December 2022, and discovered that 26 species had recovered to no longer meet the criteria. Species that have seen improvement include the charmingly named burrowing bettong, the golden bandicoot and the bulloo grey grasswren.

Factors behind this improvement include habitat management, control of introduced predators (捕食者) and translocation of endangered animals to predator-free islands. However, the species have not been officially delisted at this time. The EPBC Act only allows species to be delisted if doing so will not have a negative effect on their survival, and researchers believe that conservation gains could be lost should management efforts be stopped.

Dr Michelle Ward, a conservation scientist at WWF Australia, told The Guardian, “The key problem with delisting species is that then they no longer have monitoring and no longer need certain funding plans.”

However, it is promising that researchers have found signs of improvement. Hopefully this will continue among these and other species!

Scientists are urging that deep sea metal mining should be stopped temporarily. They warn in a report that it can cause severe and   damaging effects on Pacific Ocean areas.

The recently-released report examined more than 250 published studies on deep Sea mining. The research was examined by the Deep Sea Mining Campaign- a collection of not-for profit organizations. The report centers on mining activities related to small metallic particles(金属颗粒)，called nodules, found on the seabed. The material can contain different metals. Increasing demand for these metals has led to a rise in deep-sea mining operations. The metals are commonly used in battery manufacturing and other technology products.

However, the scientists warn that mining for these nodules will cause irreversible(不可逆的) damage to an ocean already under pressure. The operations will affect areas across the South Pacific, including the nations of Kiribati, the Cook Islands, Nauru, Tonga and Papua New Guinea.

The report notes that a moratorium is the only responsible way to move forward until certain conditions surrounding deep-sea mining can be met. The scientists are calling for additional study to fully understand the environmental, social and economic risks.

Andrew Chin is the report's lead researcher. He says in a statement that nodule mining will likely result in the loss of sea life and cause damage to deep seabeds for thousands of years. He adds that the operations can put people at risk who depend on the ocean and its continued health.

A company planning to be one of the first to carry out mining operations in the area is Canada's DeepGreen, which aims to begin by 2024. It seeks to mine metallic nodules to be used in power systems for electric vehicles. DeepGreen Chief Executive Officer Gerard Barron defended the company's plans in reaction to the report. He said deep-sea mining offered the best alternative to surface mining, which has & long history of pollution and destroying forests and wildlife.
