silent springs is really good , actually!
pathos means pity or sadness, so...
i would expect it would be the last paragraph, Yet every one of these disasters has actually happened somewhere, and many real communities have already suffered a substantial number of them. A grim specter has crept upon us almost unnoticed, and this imagined tragedy may easily become a stark reality we all shall know.
because in the other paragraphs , its not really talking about tragedy, and until you read the last paragraph does it really make scence. thankyou.
