Report: Africa wildlife down 80%; tropical forests weaken

· Climate

Africa's monitored wildlife populations have declined an average of 80% since 1970, according to a new global assessment released Oct. 8, which also points to pockets of recovery where conservation efforts have been maintained for decades. Separately, new research shows ozone pollution from fires, along with extreme heat and drought, is further weakening the Amazon rainforest's ability to absorb carbon dioxide. Forests absorb more than a quarter of human-caused CO2 emissions each year, more than 11 billion metric tons, but that capacity is degrading.

Why it matters：These findings quantify the twin losses of biodiversity and carbon-sink capacity that underpin global climate and conservation policy.

Key points

  • Africa's monitored wildlife populations fell 80% since 1970.
  • Some areas show recovery where conservation has been sustained.
  • Forests absorb over 11 billion metric tons of CO2 yearly.
