We live within a capitalist economic system that encourages the mass production of livestock, entailing horrid, close-quarters living conditions for these animals. This creates an environment conducive to the mutation of viruses and increases the chance that these viruses will jump to humans.
So what do we do? We ignore the excessive agricultural system that creates this scenario and try to deal with its consequences. Treat the symptom and not the disease. Profit is profit though, I guess.
