Answer:
One of the major goals of environmental science is to understand and to solve environmental problems. In order to accomplish this goal, scientists study two main types of interactions between humans and their environment. One area of focus is on how we use natural resources, such as water and plants.
Explanation:
Environmental science is important because it enables you to understand how these relationships work. For example, humans breathe out carbon dioxide, which plants need for photosynthesis. Plants, on the other hand, produce and release oxygen to the atmosphere, which humans need for respiration.
<span>The problem with anaerobic respiration is that it only secures about 5% of the energy that breathing does, and produces byproducts like carbon dioxide and lactic acid as waste. Carbon dioxide isn't so bad, but lactic acid is toxic and is difficult for your body to get rid of.</span>
