The orange-bellied parrot

"The species is one of the few long-distance migratory parrots in the world, and flies between Tasmania and mainland Australia annually. The orange-bellied parrot has lost 62 per cent of its genetic diversity in the past 200 years".

Orange-bellied parrots last chance for survival may be cross species breeding

The endangered orange-bellied parrot has lost 62 per cent of its genetic diversity and can only be saved by breeding with another species or editing its genes, a study suggests.

Visualizing Global Gold Production Over 200 Years
Although the practice of gold mining has been around for thousands of years, it’s estimated that roughly 86% of all above-ground gold was extracted in the last 200 years.
With modern mining techniques making large-scale production possible, global gold production has grown exponentially since the 1800s.

Invasive species such as feral cats are the number-one driver of biodiversity loss in Australia, UN report shows

"Australia is the mammal extinction capital of the world and cats have played a role in two-thirds of mammal extinctions over the last 200 years"

"Every year, cats kill 2 billion reptiles, birds and mammals in Australia. That's almost 6 million every night."

"Australia has close to 3,000 invasive alien species estimated to cost Australia approximately $25 billion every year in losses to agriculture and management costs," CSIRO chief research scientist for biosecurity Andy Sheppard said."

The report "found 45 per cent of all countries did not invest in the management of biological invasions and only 17 per cent had national laws or regulations addressing the problem".
