Since the dawn of civilization, only one kind of predator has truly threatened us. The microorganisms that cause disease consume us from the inside out.” They also reproduce much faster than we do. By evolving much faster than we do, microbes have eluded the body’s defenses, and left their mark on our history. Until recently, we were virtually defenceless against infectious disease, but in the twentieth century scientists began to focus on the antibiotics that would kill disease organisms without harming the human body. But the microbes that cause infectious diseases are also evolving drug resistance.
“We’ve created this problem,” a researcher tells us. “Multi-drug resistance is a man-made problem.” This is because antibiotics are being used too much. “By developing as many antibiotics as we have over the last fifty years, we’ve essentially accelerated an evolutionary process. The outcome is that we’re going to
have more drug-resistant microbes—to the point where some of the most dangerous bacteria will not be treatable. We’re racing against the microbe every day, and unfortunately we’re losing. There may be a solution, however. “In an arms race without end, the more drugs we launch at microbes the more resistance they evolve. It may be time to change our strategy, and make evolution work for us.
Microbes are an important part of our world, we are told, yet we seem to do everything in our power to avoid contact with them. “Is it possible we’re making our world too clean?” Research conducted by the pediatrician suggests that children who live in villages suffer more from such disorders than children who live on nearby farms.She finds that children who come into regular contact with livestock are less likely to develop allergies and asthma.(Source: http://www.reviewevolution.com/viewersGuide/viewersGuide.pdf)
