planet and that humans are not different than other living organisms and that humans have a obligation to themselves and the environment (Berg & Hager, 2009). Health Hazards Humans are affected by many different things that are in the environment. Many health hazards to humans can range from disease to natural and synthetic materials. Humans can be affected by many diseases such as typhoid, cholera, bacterial dysentery, polio, and infectious hepatitis. There was a study done that showed that about 25% of disease and injury were brought upon by human activities when changes were done to the environment. By disrupting the environment it gives the agent a way to thrive, like the process of deforesting, land development, and building dams. This process places humans in contact with new or existing diseases and assists the distribution of disease-carrying organisms such as mosquitoes which increases the possibility of diseases spreading. Humans can also be exposed to chemicals that would be considered safe, such as sodium chloride (table salt). High exposure to table salt can kill a 1 year old child if he or she ingests about 2 tablespoons. Table salt is also harmful to people with heart or kidney disease (Berg & Hager, 2009). Conclusion Environmental science is an interdisciplinary field that covers both physical and biological aspects. Environmental sciences can include ecology, biology, geology, chemistry, and many more. Not only does it involve the animals or ecosystems of the Earth it also includes the effects that humans have on the Earth.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
