Who benefits from the study of the environment?
The answer to this is the government, the people, the animals, and the land. Many of civilizations have collapsed due in part to the misuse or misunderstanding of the environment: See Collapse, by Jared Diamond. By understanding the environment in which we live, we can make conditions better for not only ourselves but also the land we live on and the crops for which we depend on. Our appreciation for wildlife and natural resources can be supported through educational awareness. Not only our children, but our politicians, farm and business owners should understand the consequences of their actions on our beautiful and fragile world.
How do we master the concepts of mathematical equations?
Again there is not a (single) correct response. Each of our brains works in a different manner and figuring out equations one way does not work for all of us. By embracing what works for you, mathematics will become much more enjoyable and far less tedious. The majority of us may not need mastery of math on an everyday basis for purposes of work, but you will find that the ability to comprehend and solve basic math problems will help reduce stress and may actually be something that you are proud of! I have personally struggled with many types of math particularly chemistry calculations. I did not truly grasp the concept of such calculations until my wife, who is much more patient and understanding than the average teacher, took time to walk me through the process. I would like to extend to you the courtesy of patience which she allows me on an everyday basis.
Why do we need to study human genetics?
There are many correct answers to this question and one answer may be more relevant to some than others. Therefore, I will answer this question as comprehensively as I can (which in the scientific community should bring about more complex and interesting questions). We study human genetics to provide better care, treatment, and counseling for patients and family members affected by genetic disease. Often, when an individual is affected by a genetic disease, family members will be frightened that they may also develop the disease or have a child or subsequent children with genetic disease. We study human genetics so that we may understand the underlying causes and so that we may provide the most accurate information to families and clinicians. In the bigger picture, we study human genetics to better the gene pool of the world. We want our species to succeed and evolve in a manner which will give us the best chance of survival. To do this, we study what we are made of so that we may provide accurate information to individuals who can make reproductive decisions based on the specific make up and structural arrangements of their own chromosomes.
