Recently I recalled a cartoon I used to watch as a kid called Captain Planet. It was a cartoon that helped promote eco friendliness and saving the environment. In each episode there would be a villain who was polluting or causing harm to the earth and the 5 main characters with the help of a superhero named Captain Planet would have to stop them and save the earth from destruction.
As a kid, I thought the show was ok but I can remember being very aware that is was really trying to push a message on us. As an adult I actually like that it was trying to teach kids to be good to the environment, but as a kid, I was more interested in cartoons for entertainment, not for a message. I think the environment is an issue that kids of a young age don't have much interest in.
For example, when I was a kid, we used to play outside each day and I don't ever recall there being litter around the neighborhood. Just recently I went back to my old neighborhood and noticed there was in fact a considerable amount of litter around. Now it could be that the times have changed, but it is likely that I am just a lot more aware of the issue as an adult.
These days I am definitely more interested in helping keep the environment clean. Although I was not really interested in the message back then, who knows, maybe some of those lessons got through and made a difference!
