For our final session of this series, we’ll be talking about how whales and dolphins fit into their/our ecosystems. How do they keep change moving along so that the system is healthy? How about humans in ecology, and humans in social systems? How do you affect your social and environmental systems? Like Whales and Dolphins, humans are very communicative creatures. One way we promote change is by writing, and by letting others read our writing! Today, we are going to write letters to seaquariums, aquariums, and government officials — and encourage them to get on board with ending captivity practices, and with freeing these remarkably wise and powerful creatures to appropriate sanctuaries.
