    "climate change" is too mind a term for what’s happening. Needs to be drastic, like "climate degradation" or "climate destruction"

    it’s unfortunate that human influence in climate change has lead many of Earth’s wonderful species and ecosystems to be endangered. I will do my best on my part, but I hope that we all can do our best as well.



  25. Nancy Reed on May 19, 2022 at 8:25 pm

    I lived on Grand Cayman 40 years ago and it was and is illegal to take any coral specimens. Take a picture…don’t take a piece! Horrified that Maui waters was devoid of coral in 2014.
