Type of Erosion Control<span> </span>Pros of Using this Control
- Jetties - protect buildings on beaches from losing sand
- Breakwaters - Stop the waves from hitting the beach

Cons of Using this Control
- can seriously affect the tidal circulation and the health of wetlands
- changes profile of the beach
- can cause bottom organisms and habitats to e smothered by muddy water
- can make the beaches difficult to use for recreation
<span>Paragraph:
</span> I think that Breakwaters<span> are the best to use. One reason is the only major con that is has is changing the profile of the beach instead of harming wildlife and taking away funding (recreational use.) Another reason is that the rocks used provide great climbing tools for beachgoers and might entertain them.
