Climate change is not one problem with one fix. Different people and groups can act in different ways, and some of those ways only work if somebody else acts first. Today you sort real strategies by who would actually have to do them, and argue about the ones that sit in more than one place.

The same climate problem looks different depending on who is acting. One crisp picture per actor is enough:

• Individuals: a shorter car trip on foot or by bike
• Communities: a street tool-share or repair morning
• Businesses: a shop changing packaging
• Agriculture: a farm changing fertiliser use
• Governments: a public transport budget or a fuel tax

First, watch one worked example sorted with the class. Then, in pairs, open the interactive activity. Drag each strategy into the actor group that would have to make it happen. If a card could sit in two boxes, pick one first, then be ready to defend the other. When your pair finishes, compare two placements with the pair beside you and mark any card you still disagree on.

1. Which card caused the most disagreement in your pair, and what were the two strongest reasons?

2. Name one strategy you would welcome and one you would resist. For each, say who still has to act, whether you like it or not.

You can now:

• name five kinds of actor who can address climate change: individuals, communities, businesses, agriculture and governments
• place a sustainability strategy with the actor who would have to carry it out
• explain why some strategies need more than one actor, and why people can disagree about where a strategy belongs without the sort being pointless

Next time you will weigh which of these strategies would make the most difference, and practise arguing that without treating disagreement as a failure.
