To Eat Horses or Ride Em

100 years ago we had no oil and horses. 100 years from now we will have no oil or horses. We must look back to a time before oil if we are to survive the future without it. The only energy will be forests, (they're disappearing to make paper and other products) wind, (mountain tops are being severed off for coal) and horses, (they're being rounded up for greed). Horses have been here for 20 million years and have done more to advance mankind then almost any other thing. Had the original Americans used  them instead of eating them they may have sailed in boats to Europe long before Columbus sailed here. Horses are an energy source that can work all day powered simply by grass. As humans consume all the earth has to offer we better consider saving our wild horses. They breed by survival of the fittest and natural selection, enhance the environment, and are social, which enables them to work with people. This all sounds so far fetched but not that long ago people lived relatively decent lives without oil. What energy is left must be used wisely. We need food, (farms) clean water, and maybe horses if we want to have humans as part of this planet because earth would do just fine without us. Please comment on your feelings of how we will face the future without oil.
