If Biology 103 has taught me anything this semester, it is that nothing and everything matters. Everything matters in the sense that there is no such thing as a real closed system and everything is related; the progression of everything affects everything else, in some complex way. Nothing matters in the amazing sense that, to our current knowledge, only humans consciously care about life on Earth and in the Universe on a long time scale… things do not “matter” objectively outside of human perception. The course has taught me quite a bit about the faultiness of human perception in that we believe our perceptions hold truth. We so easily forget other animals do not see, smell, hear, taste, touch, or sense the world the same way humans do.
