AP Biology
Elusive Ocean Trash - The North Atlantic Garbage Patch
A Public Policy Analyst (PPA) Approach to this social problem

Trash is a problem!
As our population increases, so too does
the consumption of materials that must then be disposed of. Often
times that disposal leads the trash into our
oceans.

The North Atlantic patch is estimated to be hundreds of km across, with a density of over 200,000 pieces of debris per square km. The debris
zone shifts by as much as 1,600 km north and south seasonally, and drifts even farther south during El Nino times, according to NOAA.

Define the Problem Start by stating the problem
What is it? Where does it occur? What are undesirable consequences of
this problem?

Gather Evidence Do some research!
Google is a good place to start…but… Statistics are better! Surveys Case Studies Scholarly articles
Remember to cite your sources!

Evaluate Exisiting Policies What is one current policy to deal with
trash in our oceans? Advantages/Disadvantages to this
policy? Should this policy be replaced?
Strengthened? Improved?

Develop Solutions What are 3 new policies
that could be implemented? Who will be responsible
for implementing this? Which of your 3 policies
do you think is the most promising?

Select the Best Solution Feasibility – how realistic is this idea? Effectiveness – how well will it work? Where does your policy fall into the
matrix of these two parameters?

same problem, lets share each group’s best solution. What did you come up
with??
