An MPA is a managed protected area that includes marine habitat. Rules vary: not every MPA bans fishing. Sustainable fishing uses evidence and limits to maintain populations and reduce ecosystem harm. Removing litter, protecting habitat and cutting greenhouse gas emissions address different problems; none alone solves them all. Safety: No collection of beach waste, hooks, nets or sharp objects. Stop: Stop at paper planning. No beach visit, litter handling, fishing or household spending is required.

Materials: Paper; Pencil 1. Make four illustrative pressure cards: fish removed faster than a population can replace them; breeding habitat damaged; plastic packaging enters the sea; added atmospheric CO2 drives warming and acidification. Draw one problem box for each. 2. Copy four action cards: set and enforce science-based catch limits with bycatch controls; establish a protected breeding area with clear rules; prevent waste and safely remove existing litter; reduce emissions through coordinated energy and transport choices. Match each to its most direct pressure and write why. 3. Copy this illustrative fish model: after reproduction and other natural losses, a stock would have 120 fish; catching 30 leaves 90, catching 10 leaves 110. If the starting stock was 100, compare the two end states. Label these assumed practice numbers, not a real catch quota or advice. 4. Choose a two-action plan for the habitat and CO2 problems. State what enforcement or monitoring would be needed. Add that international climate agreements coordinate emissions goals; their effects depend on implementation, not the agreement’s name alone. Done: Finish four reasoned matches, the stock comparison and a two-action plan with one monitoring need. Proof: Keep the pressure/action page. Record help with stock numbers or choosing actions. Stop: Stop at paper planning. No beach visit, litter handling, fishing or household spending is required.
