>We don't need gas, or oil, heck we can even survive without electricity. We can make do. But we die without water I understand that this is not your primary point, and I even understand the sense in which it is true, but I think it's short-sighted. People will die without oil, electricity and silicon chips because we've come to depend on them for such things as medicine, agriculture, waste processing, etc. Things like your run-of-the-mill plastics are very much a matter of life and death.
