2. It’s much easier to keep trash out of the environment when it’s on the beach than once it gets into the ocean
I know this because as part of the research team of Coral Catch, I participated in multiple beach clean-ups, but also in a Dive Against Debris. This is a dive where one takes a mesh bag underwater with them and fills it with trash that they find on the reef, or on the ocean floor. It is significantly more complicated than a beach cleanup, with all the equipment, training, time, and money that is required to dive.
Anyone can participate in a beach cleanup anytime without it costing them too much. Additionally, beach cleanups are considerably more efficient than these dives, if one looks at the amount of trash picked up in a unit of time. That’s why it is in all of our best interests to pick up trash while it’s on the beach, before it gets into the ocean.
