Proposed species extinction target fails to capture the diversity in biodiversity

We believe the 20 species extinction metric is a retrograde proposal, which does not adequately consider the lessons learnt from the 2020 Aichi Biodiversity Targets. Whilst having a single simple overarching target is appealing, we believe a positively-framed target will garner support, rather than one that aims to, at best, limit negative impacts...

Grass carp egg survival is compromised when they settle on streambeds and are potentially covered by sediments, according to a new study by the U.S. Geological Survey. It has been long assumed that the eggs of Asian carps, including grass carp, must be carried in the water current in order to hatch successfully, but no previous scientific studies have proven that theory.
