    The world is running out of patience when you treat us like slaves. Beware, you have been warned.

    Another of "The world is coming to an end" scenarios. In the early 70's we were told that oil is running out, now we know that we have more oil and gas then we knew of in the past. If the problem is too many people, then everyone knows how they can personally bring down the population numbers. The world is always coming to an end for one reason or another, nothing to get excited about.

    when you ask for an alternative to sand and they answer more sand....smh....I understand its recycled sand but every time it is recycled you lose some of the product in the process whether its from the actual process or not 100% is being recycled you are still gonna run out and have to return to the original resource eventually....when I hear of an alternative resource I want to hear something that is actually an alternate and not just the same thing but re-packaged under a "green" label....
