Final answer:
The statement that overfishing will lead to an increased fish population is false. Overfishing causes fish populations to decline and can result in the disruption of marine ecosystems, affecting both biodiversity and human communities that rely on these resources.
Step-by-step explanation:
The statement that overfishing in Canada will lead to an increased fish population is FALSE. Overfishing has historically led to the decline of fish populations, as seen with the collapse of the cod population in Canada. Reduced fishing pressures can give fish populations a chance to recover, contributing to healthier marine ecosystems. However, overfishing without management leads to the depletion of fish stocks and can cause a radical restructuring of the marine ecosystem. For instance, dominant species become less prevalent, altering food webs and potentially causing a loss of aquatic systems as food sources.
Additionally, factors such as human population growth and increases in greenhouse gas emissions exacerbate the stress on marine environments by leading to habitat destruction and rising ocean temperatures, which can cause further shifts in marine populations.
