How can we prevent oil spills in ocean?​

Explanation:

Boaters

Don’t overfill fuel tanks – fill to only 90 percent capacity to reduce the chance of spills. Use oil absorbent pads in the bilges of all boats with inboard engines. Regularly inspect through-hull fittings often to reduce the risk of sinking. Recycle used oil and filters.

Marinas

Routinely inspect storage tanks as required by law. Use automatic nozzle shutoffs to reduce the potential for overfilling fuel tanks. Set up an oil-recycling program to deliver used oil to a designated collection site. Keep spill control equipment readily available. Properly dispose of used oil and fuel-absorbent materials.
