A seems to be the best answer out of all four, since I use hyphens (this thing: -) between other words in sentences. The only way that there's only one hyphen in a sentence is if the words after the hyphen end the sentence, like choice B. However, B would not make sense, since I feel like there should be a pause after "unrequested". Choice D is the oddball out of all of these, since the word "though" has an unnecessary colon. I would rule that one out. So, we are left with A and C. A would make more sense, since the hyphens make the text flow better than the comma used in C.
We have control over nature in a huge extent. Humans have so much control over other things too, we have such a huge knowledge. But most of the time we take what we have for granted in nature, some people don't appreciate the beauty of it. I do feel obligated to do my part and protect the environment/refrain from causing damage or to at least make a small change.
