Water is the main source of surviving to bath, drink and wash clothes and your selves. I think they should figure out a way where it would not ruin our water system.

I think it is more bad than good because they are throwing there waste of oil into the water we live on.

To prevent shoreline erosion coastal buffs have been hardened by various rock, concrete, wooden, and steel walls.
