Answer:
With rising sea levels and coastal construction, shoreline erosion is something we should all care about.
Explanation:
In this sentence, you can see how the topic "shoreline erosion" is rehearsed and included as part of a situation that previously was explained.
<u>The Shoreline erosion and the rising sea levels as well as the coastal construction</u> form part of the variables of the thesis that wrap up the main points that determine they are all relevant to understand the importance of the topic and take a stand.
In contrast to the other options, which leave the possibility for further connecting ideas, the sentence <em>"something we should all care about" </em>coming at the end, provides a sense of closure and prompts the reader to meditate on the issue.
