"When I was a kid, we never heard of smog, ozone depletion, acid rain, green house gasses"

This quote by Dennis Weaver reflects on the ecological changes that have occurred over the previous couple of decades. He is expressing his surprise at the truth that when he was a kid, he had actually never become aware of environmental problems such as smog, ozone exhaustion, acid rain, and green house gasses. This suggests that these environmental issues have only become prominent recently, which the environment has actually changed drastically since Dennis Weaver was a child. This quote serves as a pointer of the importance of looking after the environment and protecting it from further damage. It also highlights the need for more research study and education on ecological concerns, so that future generations can be aware of the risks of environmental degradation.
