  1. The Great Pacific Garbage Patch (GPGP) is a swirling mass of plastic that you can see from space. The search for missing Malaysian Airlines flight MH370 highlighted this environmental disaster and brought it into the public spotlight. Taking a look at the GPGP is a sobering way to realize there is no “away” or “dilute” option when it comes to trash, especially for trash that cannot be decomposed.

    These two sites: Episode 126: The great Pacific garbage patchand Great Pacific garbage patch highlight the GPGP.

    Develop a 1-2 page essay on how the GPGP attained such an enormous size and what can be done to minimize its negative impacts on marine environments. You are not being graded on your opinion, but on how effectively you can back up your opinion with facts and documentation. Please cite all sources according to APA format.
