The Answer

The question in this edition is:

What species is no longer likely to go extinct?

The answer: CA Condor

Only 22 California condors existed in the world in 1982. Most people assumed they would soon become extinct, so scientist captured the remaining birds and started breeding them in captivity in order to save them. In July of this year, the birth of the 1,000th chick occurred and the total number of living condors reached around 500 – with more than half living outside captivity. They are still endangered and not recovering as quickly as expected. Recent research shows the greatest danger to the birds is lead poisoning from eating dead animals killed by humans using lead-based gunshot. California recently banned all hunting with lead-based ammunition in an attempt to reverse this problem. Read more about the comeback of the California Condor.
