I believe the answer is that under natural conditions oceans are self-cleaning systems.

Answer:

Under natural conditions, oceans are self-cleaning systems.

Explanation:

  • The oceans usually do not house any waste, unwanted material in themselves.
  • The ocean waves either dispose off the waste material back on the shores, or the saline ocean water decays the degradable material.
  • The marine organisms are also majorly responsible for keeping the oceans clean. These animals eat up edible waste and control pollution in the oceans.
  • The lavas erupting at the bottoms of the oceans burn up the nearby non-biodegradable material.
  • Thus, in natural conditions, oceans are self-cleaning systems.
