I have taught Earth/Environmental Science (high school) for 5+ years and the lack of interest about the environment and the impact that each of us has on our surroundings by so many of our students is absolutely horrifying. >
While much of this disinterest is the result of lack of education and role models, by the time these kids get to high school, they ought to have developed some empathy and not laugh when they see pictures of birds or manatees caught in debris. While it can make you sick to think about these twisted minds, all I do is try even harder to instill a sense of respect and responsibility towards our surroundings in my daughters. They are only 3 and 2, but they can identify several bird calls already and are always overjoyed when they see a butterfly. I hope that enthusiasm never fades for them!
