You always hear those lines of motivation that in order to persevere one must have sacrifice. An equal exchange of energy in a trading fashion of give and take. It seems like many advancements have taken place over many of the years. Corn can be grown 3 inches closer due to GMO's but those same GMO companies threaten not the environment but the lively hood of generations of farmers using seed handed down threw time. See GMO is a copy write, and if you happen to have a field next to a neighbor with GMO and like all plants pollination takes place due to a simple unstoppable cross wind that seed in the non GMO field is now GMO and because its copy righted if the farmer doesn't throw the seed away he risks losing his farm to the company that made the seed.

Another point is Global warming, which science backed as fact. The main reason was hair spray, CFCs where eating the ozone. A simpler propellant we thought harmless. Or Teflon cook wear, we never new that stuff was going to flake off into your morning eggs. We didn't know that eating an explosive agent as a sweetener would carry health risks either.

I think that the world is evolving at a rapid rate, perhaps too fast for some tech concepts or "wounder" materials. Most of items now a days have a concept put into a product in a matter of a few months to a year and its on a shelf.
