Biodiversity: A Call to Action
summary
Biodiversity loss proceeds at roughly 100 times the rate of past mass extinctions, driven by overexploitation, invasive species, pathogens and habitat conversion. Illegal caviar harvesting leaves 26 of 28 sturgeon species threatened. Field work finds critically low numbers and infertility in Sumatran/Bornean rhinos — only five rhinos in Sabah in 2009 — prompting tissue cultures and assisted‑reproduction attempts. Practical fixes include moving cattle away from cheetah kill hotspots (losses stop) and shifting turbine cut‑in speeds (at a ~5% energy cost bat mortality falls dramatically, saving ~200–300,000 bats/year in Germany).
