Expand bottle deposit programs to cover all consumer packaging—cans, bottles, cartons, and containers. A small refundable deposit (10-25 cents) creates a financial incentive to return packaging for recycling rather than tossing it in the trash.
Design and publish open-source plans for hydroponic systems built from common hardware store materials (PVC pipes, plastic bins, aquarium pumps). Total cost under $50. Include step-by-step video tutorials and a community forum for troubleshooting. Projects like OpenAg and Farmbot have shown open-source agriculture works.
Permanently close select downtown streets to private vehicles, converting them to pedestrian plazas, bike lanes, and transit-only corridors. This reduces emissions directly while making walking, cycling, and transit more attractive. Cities like Oslo, Barcelona (superblocks), and Ghent have seen air quality improvements and increased retail activity.
