The golden toad... extinct!

The world may be entering its sixth era of mass extinction.

At one point in the elfin cloud forest of Costa Rica, golden toads would leap around in abundance, a representation of the forest's well-being and prosperity.

"The soils are very dark and so golden toads would stand out like animal figurines. It was quite a spectacle," said J Alan Pounds, an ecologist at the Monteverde Cloud Forest Preserve, Costa Rica.

In 1990, the golden frog, suddenly, was gone - because the toad could only be found in the Monteverde forest, its extinction was total. Upon its realization, causes were assessed to find out that climate change is the driver behind the extinction. Climate and the biodiversity crisis are interconnected.

Top corporations fall short in fighting climate change

Some of the world's largest corporations are failing to live up to claims that they will achieve net-zero emissions targets, reducing carbon emissions by only 40% rather than the projected 100%, according to a new analysis.

Amazon, IKEA, Nestlé, and Unilever are among the firms cited as having little substance behind their assertions that they will dramatically reduce emissions.

The report's compiler, Thomas Day of NewClimate Institute, stated that the combined efforts of the 25 companies analyzed would have little influence. "It's unclear whether these cuts go beyond business as usual," he said. "We were both dissatisfied and surprised by the amount of opportunity for improvement [among the companies surveyed]. Companies must be far more open about their objectives."
