What can Congress do about the looming climate disaster caused by fossil fuel combustion?

 Why is there no fossil fuel tax (on oil, coal, and gas)? Why are the fossil fuel companies still getting tax breaks but solar, wind, and other non-polluting energy sources do not? Why is there not a "luxury tax" on new vehicles that are not electric? Why are the tax incentives for electric vehicles not higher, using "luxury tax" and fossil fuel tax to pay for them? Why is solar plus battery not more emphasized as a way to avoid PG&E power outages? Why is packaging that uses fossil resources not legislated out and taxed? 

Report unleashed dogs and their owner

A reasonable response for unleashed dogs and irresponsible owners is to read and carry a copy of the animal services ordinance (https://library.municode.com/ca/marin_county/codes/municipal_code?nodeId=TIT8AN). Be ready to quote relevant sections, especially 8.04.260 - Penalty for violation. Do not be confrontational or threatening, but video your interaction with the dog and owner with your phone especially while the dog is threatening you, and any interaction with the owner. If necessary or requested, send the video to The Marin Humane Society (https://www.marinlafco.org/marin-county-animal-services-marin-humane) or 415-883-4621 and ask for assistance. 

Of course, if you feel physically threatened by the dog or owner, call 911. This applies to any animal, including coyotes, wildcats, etc. 

You might consider carrying a large, automatic-opening umbrella. This appears to increase you size and can act as a shield if necessary. Pepper spray would also be useful.
