Irresponsible collection of wild species for aquariums and overfishing threaten many of Hawai'i's reef fishes and invertebrates. Please don't pollute. In the main Hawaiian Islands, pollution from land finds its way into our oceans and reefs. Use fewer household chemicals, especially on your lawn or garden. Become involved in monitoring and preventing wastewater pollution.
