Question1)
Comment on Toxoplasma Gondii. What do you think??
Thinking about how parasites ( and diseases in general) can affect behavior  really makes me wonder about how and why things happened in the past, and how and why things will happen in the future. Were some of the "bad things" that happened in history due to someone being infected with a parasite or a disease? If so, how would it have been different had that parasite been eradicated prior to that person being born?

When we think about almost everything which is smaller, it has capability of effecting large on almost anything. Let's think about chemical element O2, it is very micro,even our eyes could not even see, but O2 is the only element which provides all organisms including our self. Without O2, we can not live. How about parasites? Parasites has the essential role to your clean environment, any parasite lives any environment such under water, over water, or land has their role clean up that environment by eating human pollution, dead animals. Without Parasites our environment will not be same as today. Since everything has 2 sides, parasites also can be consider bad things for generating diseases. In order to understand the root of parasites generating disease, Parasites contains some bacteria which is not suitable for humans, so therefore we need to understand what kind of bacteria they contain, what they eat, what might have been changing in their environment etc. Parasites are sometimes immigrate from environment to another which might cause the diseases to the new environment. Some of the causes are from human accident such as oil spill at golf of U.S. Golf spill might cause parasites to clean something that they have never experience, and then from eating oil under the sea bottom, parasites may change even they can become sick which might effect to the other marine animals. Only animals working 247 cleaning up oil spill at Golf of Mexico are parasites. So someone may say parasites are bad they generate disease, but someone might say No they clean up the environment.
For future, I think we need to careful about what we are doing right now, especially knowing at least try to consider small animals live in the certain environment.
 It's not a Invasion of any parasite has been affecting how things were changing, it's partially us that we are changing the way parasites live. Everything in past and everything now will change forever. Welcome to Earth.
