I am a firm believer that everything on earth has a purpose. When there is a bug in the house, I catch it and put it outside. When I am mowing and see an ant hill I either raise the deck or go around it. I will not spray dandelions because it may kill the bee's that may land on them.  I compost all vegetation waste from our house. Every farmer that will listen to me gets an earful of what they are really doing to the planet. I wish there were more I could do. We have to be good stewards of this planet.
