Habitat destruction causes what percent of extinctions?

“0.36” for habitat destruction causes what percent of extinctions.

Extinction risk rises when abundance, geographic range, or genetic variation becomes small because demographic chance, environmental fluctuations, inbreeding, and rare catastrophes then have disproportionate effects. Correlated losses among subpopulations further weaken regional persistence. The remaining alternatives—“0.23”, “0.434”, “0.38”—refer to different states, processes, or sc
