Here's a thought, why do we need to cure every disease? Disease is a natural population control. When a species reaches it's population capacity point, the number of individuals a certain environment can sustain, and then goes past that point, things such as disease, starvation, and predation bring the numbers down. Well, you can cross out predation, because there is no species on this planet that can successfully maintain a dominance on the food chain above humans. If we eliminate disease, all that is keeping us in check population wise is starvation. The fact that we can think outside our own species and consciously damage our own environment without thought of the consequences puts us in a VERY difficult situation. We, as highly functioning beings, look to protect our sick and weak beyond that of natural instincts. We decide to overcome natural barriers. And we are paying the price. The earth is starting to try and shake us like a bad habit. It has unleashed disease, natural disasters, and now the environment we need to survive as a species is slowly becoming nonexistent. I think we need to worry less about curing a disease that in the end will not wipe out our species, and look for ways to save ourself from extinction. I know this sounds cruel, inhumane, pessimistic, but this is the reality of our situation. Anyway, just something to think about.
