Uneaten food decomposes and releases gases. Production resources, like transportation, are wasted.

Gases, like CO2, build up in the atmosphere like a blanket.

This traps heat and warms our atmosphere.

The warming atmosphere melts land-ice and warms the ocean.

Warm water expands and leads to sea-level rise.

Rising sea levels threaten our communities.


  • Share a plate when dining out.
  • Use up your leftovers, or freeze them.
  • Eat “ugly” produce.
  • Take note of what you already have before buying groceries.
