This week’s segment explores efforts in Hawaii to grow corals resistant to bleaching.
Scientists are attempting to speed up evolution in an effort to save coral reefs.
This is the Iowa Environmental Focus.
Biologists at Gates Coral Lab at the Hawaii Institute of Marine Biology are working on a way to cross-breed coral species that have resisted coral bleaching or persisted in spite of it. Coral bleaching, a phenomenon that has been slowly killing reefs for years, occurs when corals are stressed by environmental factors, such as pollution or extreme temperature changes.
The Biologists at Hawaii’s Coral Lab are trying to cross-breed resistant species of coral to create something like a super-coral—a variety of coral that can withstand these environmental stressors. This plan is sometimes referred to as assisted evolution, when scientists help speed up the process of evolution to yield stronger varieties of creatures.
Dr. Ruth Gates, director at the Hawaii Institute, isn’t sure if coral reefs would survive past 2050 without some assistance.
