An oil spill can affect bird nesting near a contaminated body of water through its food chain.

<h3>What is oil spillage?</h3>

Oil spillage is defined as the release of used or oil wastes into a water body through a tanker, offshore drilling rig, or underwater pipeline.

The area affected by the ship that were involved in an accident can be calculated by the addition of the various areas affected by the tanker, ship and super tanker.

That is, 32,000 + 1,200,000 + 332,000,000

= 333,232,000

Which is approximately 333 million liters.

A bird that is nesting near the contaminated body of water can be affected through its food chain.

This is because birds which depends on fish can eat fish for this contaminated water which must have accumulated some level of harmful organic substances on its body surfaces.
