Answer:
A life jacket is important for several reasons:
Drowning prevention: It helps individuals stay afloat and maintain their head above water, reducing the risk of drowning, especially for those who are not strong swimmers.
Safety requirement: Many jurisdictions mandate the use of life jackets in certain situations, such as boating, water sports, and for children.
Cold-water protection: Life jackets also provide insulation, keeping the body warm in cold water and potentially preventing hypothermia.
