I am a vegan. This is the first and most important sacrifice.
I live in WA, eastern side. The fact that I live in a house is problematic, but we are keeping it cold inside. I must wear a jacket inside my house right now to be comfortable. This is almost nothing compared to having been a vegan for the last 15 years.
I drive less than 3k miles a year, work from home, and I'm going to start applying the wealth that I have to sealing up my home insulation-wise (it's old). This is almost literally nothing compared to having been a vegan for the last 15 years.
I have made a vow to never do personal travel by plane again, and will never cross an ocean for the rest of my life. My company has me going across the country twice a year for meetings, but they are about to reduce it to one, I think, and if we improve our train systems, I'm very happy to do a two day train ride to get there, if at all.
My wife and I love animals, and it's the main reason that we have a house. We will not be replacing them as they die. Ultimately my goal is to pay off the current old house that I have, and then either try to fill it with far more people, or have it demolished as I move into an apartment in town, which is a far more efficient way of life.
Almost all of my conversations discuss climate change in some way. In order to get the political pressure that we need to fight this, our culture must change. These comments are part of that key work.
I am not waiting for anyone. I am trying desperately to walk a path without exploitation, and it's incredibly difficult. I cannot expect my family to walk the path to the extent that I desire either, but we are all vegan and don't travel long distance, and these are the most important changes individuals can make.
You can rail upon my imagined hypocrisies if you desire. You can also join me if you wish.
