Giant sloths spread avocados around the world

In fact, we might not have avocados today if not for the giant sloths.Smaller animals couldn't swallow the avocado's huge seed,but the sloths could,and they spread avocado trees far and wide.Ground sloths flourished for millions of years,but around 10,000 years ago,they started disappearing along with the Western Hemisphere's other giant mammals.Researchers think that ground sloths could have been pushed out by an oncoming ice age,or competition with other species,maybe humans,who arrived in the region around the time most of the sloths went extinct.Some of the smaller sloths did survive and migrated to the treetops.
