A class is debating pros and cons of using sea walls to reduce beach erosion. What is the best way for them inform their decision-making?

They should each write an opinion paragraph to send to the local paper.

They should hold the debate on stage, so that they can be judged.

They should watch movies about beaches.

They should research wave action and collect data about erosion in the area.

They should research wave action and collect data about erosion in the area.

Explanation:

everyone has their own opinion, and movies aren't gonna make the cut, and no one wants to see a debate in school, so they should research first to get the info they need

it's unlikely a majority of a large population would agree on issues

hope this : )

hey, what do you need . just post the question and i may be able to you : )
