Wetlands and estuaries are critical ecosystems, but do not require protection.

False. Wetlands play a very important role in the ecosystem. Wetlands act like a sponge, soaking up storm surges, and trapping polluted runoff. Also, they provide habitat to hundreds of fish, birds, mammals and invertebrate. But development, invasive species, and sea level can all threaten a wetland.
