Harris

In this article Harris explains the reason's behind our skin color. He says that we get our color from particles called melanin. Now with melanin "it protects the upper levels of the skin from being damaged by the sun's ultraviolet rays"(harris 7). Harris says that we as humans dont have the right of hair that most mammals have to act as sunscreen. Not having all the hair we need exposes us to lots of bad radiation hazards. The more melanin found in the body the darker the skin is and the lower the chances are for cancer and sunburn. Harris describes the process in this manner. First the sun falls on the skin and it turns into vitamin D. Our blood carries that to the intestines and it then plays a big role in the absorption of calcium. Calcium is very important for a strong body and strong bones. Different foods can give vitamin D and help with the skin. Now at different latitudes particularly the middle one the skin changes colors with the seasons. The temperature in some areas can dictate how the skin will appear. He basically states that Black as well as White is beautiful for multiple reasons. There are many factors that contribute to the pigmentation of the skin.

I find Harris's views on how we all got our skin color interesting. I do agree that our skin color has much to do with where we reside and the things we do in life. An example is when he stated that people in Australia are at a higher risk for skin cancer than the people who live in other areas that are less likely to have alot of sun.
