What is the theme of "He-y come on ou-t!" by Shinichi Hoshi? The authors purpose for writing it.

There is a strong ecological message in this story. The people disregard the environment and think that they have found an easy solution for all of the harmful chemicals they have created and all the dangerous waste they have generated. However, it turns out that their thoughtlessness for the well being of the earth is going to revisit them as their waste rains down on their heads. The author wants the reader to think about our actions as we quickly pollute and damage our environment. A few decades ago, people just dumped trash into the ocean because they couldn't see the damage it would do in the water, and just wanted to get rid of it. It seemed like an easy solution then, just throw it in and it disappears. Throughout history we've just dumped our waste in places and watched it disappear, but it never just "disappears." It always comes back to affect us in some detrimental way, whether it kills off species of animals or pollutes our water or depletes our ozone. This story illustrates the very thing that we do, we dump our problems and hope that they'll disappear. No one wants to think about it, but Hoshi's story reminds us that we can't hide our mistakes so easily, because it will come back to us somehow.
