By 2050, there could be more plastic than fish in our oceans. This is extremely harmful to the environment. Ships suffer damages. Aquatic animals get tangled in plastic. Over time, plastic turns into microplastic that aquatic animals get into their bodies. In turn, we end up eating plastic from our dinner plates. Submerged bubble curtains create a linear screen that can guide floating debris such as plastic away from entering our oceans, and instead into a collection unit.

Underwater activities such as drilling for the installation of offshore wind turbines,demining, seismic surveys, pile driving, oil prospecting, and general port and coastal development can cause considerable noise which can be lethal to fish and other marine mammals. Bubble curtains offer a promising means of lessening the impact of aggressive sound on marine mammals by confining and reducing the sound intensity and the speed over which the sound waves travel.

Coral bleaching is a climate-related impact on coral reefs. Rising (or even falling) water temperatures can stress coral reefs, causing them to lose algae. The bubble curtain can help control the sea surface temperature above coral reefs.

Submerged air bubble curtains not only reduce sound but create a linear barrier that can protect and guide particular fish species in a certain direction.

​

The bubble curtain can also be installed surrounding fish farming sites and be effective barriers against toxic plankton and algal blooms which are common explanations of declines in fish production and cause of death in salmon farms.
