They have a lot of precautions in place to avoid damaging any wild life. They move slowly, and their nets have special channels to allow animals to pass through and avoid getting caught. See the "managing environmental impact" section here: https://theoceancleanup.com/oceans/ https://theoceancleanup.com/oceans/ I imagine there must be _some_ non zero risk, but I imagine the benefits of removing the plastic outweigh the risk. Ie removing the plastic is better for the wildlife overall, despite the small potential risk.
