What are the sentences/question that wants you to do.
One part is "Unless we start listening to Mother Nature and start taking care of our lush, green planet, our world as we know it will not be around much longer." It can make the reader seem worried for the planet because they live on it and it not being around much longer than where will they go? It makes them want to help for the sake of them selves. As well as "Every part of nature is being depleted by overuse and lack of care, and no one seems concerned." People don't want to be know as "the bad guys" so they want to start helping so they won't be put into the horrible people title.
Well, let's see... I don't know what a coordinating conjunction is off the top of my head, but I know B isn't the answer, since 'independent' means 'highly capable of handling oneself'. C <em>certainly</em> isn't the answer, simply because you can see by this answer they obviously do combine with a dependent clause from time to time. That leaves us with D and A, which both leave the same term. However, I do believe I can use the word preceding <em>conjunction</em>, which is <em>coordinating</em>, to realize that 'and,' 'but,' and 'or' are coordinating conjunctions. Seriously, D cannot be the answer because not every sentence starts with any of those. So your answer is A.
