A volunteer activity where participants remove trash from waterways is called what?

• A. Stream cleanup event
• B. Citizen science project
• C. Personal environmental footprint measurement
• D. Public-private partnership

Answer: (A)

A stream cleanup event is the name for an organized volunteer activity where people come together to remove trash from waterways. This term focuses on the hands-on action of cleaning litter out of streams and rivers to protect water quality and aquatic life. The other options describe different ideas: a citizen science project involves gathering data about the environment, not primarily cleaning up trash; a personal environmental footprint measurement is about evaluating an individual’s impact; a public-private partnership is a collaboration between sectors to fund or manage projects, not the cleanup activity itself. So, the best fit is stream cleanup event.
