Biology · Environmental Issues
Why do conservation biologists widely believe that global warming may lead to rapid, extensive species extinctions?
- 1Because global warming completely stops natural selection from occurring in forest ecosystems.
- 2Because many species may be unable to disperse or shift their geographic ranges fast enough to keep pace with migrating temperature zones.✓
- 3Because the predicted rate of current global warming is significantly slower than any past natural climate shifts.
- 4Because plant communities have historically shown zero adaptation or composition change during periods of climate shift.
Correct answer
Because many species may be unable to disperse or shift their geographic ranges fast enough to keep pace with migrating temperature zones.
