Since you asked, as citizens my family and I:

Have enough solar on our roof to cover our energy use 90% of the time
Sealed our house and improved its insulation for energy efficiency
Drive a plug-in hybrid and avoid unnecessary driving
Have been pressuring our town to be less car dependent and we recently voted to create a mix-use, walkable area down town
Have started a garden to supplement our food
Recycle and try to buy products with easily recyclable, low waste packaging
Try to repair and reuse when possible
Buy used instead of new whenever possible
Try to order things locally or in the US whenever possible, from companies that aren’t billionaire owned
Vote in every election, even the little ones, for folks who make a strong stand for climate action. Talk to our neighbors about upcoming elections and sometimes remind them or even drive them to polling places
