Individual Changes
• Reduce Energy Use• Use your car less• Insulate your home• Conserve Water• Use your dryer less• Reduce, Reuse, Recycle• Compost• Choose High Efficiency appliances• Plant native trees and plants• Eat less meat• If you live on a lake, do your best to prevent erosion and to
treat runoff

Collective Action
• Get Involved in your town
• State and Federal: call your representatives
• Get Involved in local environmental groups: LEA, LELT, MLS, NRCM, etc.
• Get on email lists
• Talk about Climate Change: make it an issue
• Education is Essential

Bottom Line
• Learn: Know what’s coming & educate others
• Prepare: Put systems in place now
• Adapt: Factor Climate Change in to decisions
