"BAYAHIBE, Dominican Republic (AP) — Oxygen tank strapped to his back,
Michael del Rosario moves his fins delicately as he glides along an underwater
nursery just off the Dominican Republic coast, proudly showing off the “coral
babies” growing on metal structures that look like large spiders. The
conservationist enthusiastically points a finger to trace around the largest
corals, just starting to reveal their vibrant colors.

Del Rosario helped plant these tiny animals in the nursery after they were
conceived in an assisted reproduction laboratory run by the marine conservation
organization Fundemar. In a process something like in vitro fertilization,
coral egg and sperm are joined to form a new individual.

It’s a technique that’s gaining momentum in the Caribbean to counter the
drastic loss of corals due to climate change, which is killing them by heating
up oceans and making it more difficult for those that survive to reproduce
naturally."
