Prevention: the action of stopping something from happening or arising. Have you ever regretted something? Getting in a car accident because you were texting and driving. It could have been avoided completely if you weren't texting. If you left your kitchen sink on, walked away, and came back to it overflowing, you probably wouldn't be too happy while cleaning up the kitchen. It wouldn't have happened in the first place if you were nearby watching the sink. Have you ever had your basement flood? Perhaps something needed to be inspected and/or fixed and you had just completely avoided it until there was a foot of water in the basement. WHY wait until the crisis happens? Money, time, and energy can be saved. Think about this in a general sense. Then question what we are doing to the planet.
