Some examples of ocean systems:
3
Pollution Harmful substances mixing with the air, land, and/or water.
Technical Definition: Contamination of soil, water, or the atmosphere by the discharge of harmful substances. Image adapted from: Technical Definition: Student Definition: adapted from Access Science, page 106.
4
Overfishing or Overharvesting
Catching large numbers of fish so as to deplete their populations. Technical Definition: To fish to such a degree as to upset the ecological balance or cause depletion of living creatures. Image from: Technical Definition: Student Definition: Common Knowledge

Watershed Area of land that drains water from a higher area of land to a lower level of land and into a stream. Technical Definition: An area that is drained by a river and all the streams that empty into it. Image from: Technical Definition: Student Definition: adapted from ScienceSaurus Glossary, page 482.
