It is easy to tell when your diet is full of fresh meat/fruits/vegetables vs full of processed foods. I feel more alert and energetic when I eat right.

When walking the neighborhood you are able to do things like stop and talk with neighbors, meet new people, recognize changes and learn new things.

Limit water usage when brushing teeth (don't leave the water running). 
Limit water usage when washing pots and pans (don't leave the water running).
Monitor yard irrigation for maximum efficiency.

I can run trails in Washington Park vs run on a treadmill inside or I can text a friend to go to the gym with me.

I believe it can. Having witnessed organic farming in action, I think with the right education and sharing of knowledge organic farming definitely can be applied on a large scale.

For my region there are a few rivers and watersheds in the area where we source of our water. For me specifically, we are on well water which wonderful. Even though we don't have a rain water catch system, the rain water does go back into the water table where our water comes from. At some point, we will have rain water catch system which will be used for irrigation and grey water usage. 

I don't know if there is a way to reduce the number of flights when you have to travel for work, but I think there is a way to be more efficient with your time while you are traveling. It does make for a long day when your flight leaves at 6am and doesn't return until 10pm, however if you are maximizing the day by booking meetings or getting items done that make you not have to return as quickly, then it is worth it. I will say when I selected this challenge, I wasn't sure what the actual cost was going to be and thought it would be quite high. I was pleasantly surprised when I went to Alaska Airlines website to find out that a 2,500 mile carbon offset is just $5, according to this website: https://carbonfund.org/partners/alaska-airlines/. That actually makes me want to do that more often since I will feel better about my travel and just not buy a coffee on the trip to save the cost of the carbon offset. I will tell other people about this including whoever is reading this! 

This is an interesting thing to think about and how I can modify my habits. One of the ways I did this was to walk to one of my properties rather than driving. It is a 20 min walk both ways so I had to factor that time into my day, but I did use that time for making phone calls. I was breathing a little heavy on the calls but people were impressed that I was walking. My company also offers a bike to ride around town that I will use the next time I have a meeting close enough to bike but too far to walk and I'm thinking about driving.

A source of food for me is the motivation but that is primarily in the PNW we have amazing mushrooms, fern heads and ramps that grow wild and can be turned into delicious meals. I've always wanted to grow mushroom foraging and learned that if you stop by a ranger station they will review all your mushroom picks and let you know which ones are safe to eat or not. The ranger station wants to be helpful for people and offer to help as they want people to be aware of what is good and bad.
