Challenge your kids to a fun, 60-minute planet-friendly scavenger hunt! Plenty of household items are sneaky sources of pollutants and ecological harm–coffee capsules to single-use razors. We bet your family can find five problem products in an hour that can be replaced with more sustainable alternatives.

For example: a glass jar of loose-leaf tea can replace single use tea bags–which often contain plastic! Swap out cling film for reusable beeswax-coated cloth wraps. Or switch to biodegradable laundry detergent to help clear waterways of harmful chemicals.

Submit and bank your hour to find out which household items are unsustainable and why–and start your hunt!
