Invasive Species and the effects of the Hemlock Woolly Adelgid A specific environmental issue I would like to learn more about is the impacts of invasive species, more specifically that of the hemlock woolly adelgid (HWA).

The eastern hemlock is a very abundant tree among the eastern seaboard of the United State.

(875 words) Woolly Days ahead for the Hemlock Tree -Angela Cannon-Crothers I like bugs, ask anyone. I am awed by the mechanics of their life cycles, the biodiversity of the entire Order of Insecta, the magical beauty of so many of their kind. But there are a few that strike more than a few heebe-geebes -- some are downright frightening. Take the tiny hemlock wooly adelgid (ah-del-jid) for instance: a needle sucking scale insect of miniscule proportions that reproduces asexually (no male…

The Native American Health and Medicine talk was very interesting talk given by David G. Hilmey from St. Bonaventure University. He focused on Ethnoscience, which looks at the indigenous knowledge systems to connect culture with science. He is a synthetic organic chemist. He focused on The Seneca tribe, which is about 8,000 citizens. In particular, the Faithkeepers School. The course he focused on was medicine and health. A issue he came across was the youth not being involved in the Seneca…
