The TED talk addressed the problem of infectious diseases and how they spread using the examples of cholera and malaria. Speaker Paul Ewald discussed ways in which humans may have the ability to reduce exposure and spread of infectious diseases by applying the theory of evolution by natural selection. This spread of the disease poses a threat to humans as the bacteria that cause the disease evolve with humans and become resistant to medical interventions. The speaker addressed some key issues and proposed some important solutions towards improving human life. The field of biological science studies when it comes to man's work towards understanding the evolution of humans and threats to the survival of our species. Understanding the evolution of diseases is important to create ways to protect humans from these diseases and properly treat infected people. There have been some success stories in the 21st century where science has been successful in combating irradiated diseases through the use of antibiotic research and development, but there are still diseases that plague especially developing countries. Lack of information about diseases and the effects of diseases on humans can be critical to human survival if diseases evolve beyond our control and can lead to a pandemic. The issue presented in the topic is to find the right way to deal with the spread and threat of the disease, one side approaches the issue by looking from the human point of view while the other looks at the issue from the organism's point of view. Paul Ewald approaches the issue from the organism's point of view and develops methods to combat organisms. In the speech... center of paper... Just as in the case of AIDS reduction, reduction occurs after exposed people are given information on how to reduce their exposure. Reducing transmission is as easy as teaching children to wash their hands and where to use the bathroom, which costs much less than antibiotic treatment (Esrey et al. 1985). The ultimate goal of infectious disease research is to find a way to protect humans from harmful effects, so it is critical to provide people with ways to reduce their exposure. One of the challenges for humans in the 21st century is the fight against infectious diseases, as our knowledge of medical treatments increases and drug-resistant diseases simultaneously increase. Research in the biological sciences department involving the domestication of germs can be a solution to control the evolution of germs for our benefit, improving the life and survival of the human race.
