A guy off the coast of California runs a whale spotting business. One day out on the water a whale pays him a visit. He pops his massive head next to the boat. The guy pats him. He also notices algea affixed to the creature's head and body. So he picks some off with his fingers. The whale likes that and repeats the experience. The guy keeps removing the algea from the whale. Next time out on the water the whale is back for more. And it continues on to this day. So this big whale is sensitive to very thin algea on it's skin. What do you think the whale feels when it is shot with a harpoon. Let the whales live on. Us humans are suppose to be the stewards of this world not to drive species into oblivion.
We have to realize that our actions do matter and they do have consequences. One of those consequences could be our own destruction. When man and woman realize that they have a relationship with God, they will make better choices for their lives and others as well. Talk to God in your head and ask for his guidance. Eventually that quiet little voice will speak up. Listen to what it has to say.
