We all have our ways of making concessions to protect the environment. Some of us never use a plastic bag, others refuse to use a dryer. If you really want to make an impact reduce the amount of beef and products that contain beef. The environmental footprint for one head of cattle is huge.
Many if us make the environment a priority in our daily lives and splurge on vacation. That may mean you eat steak every day, use fresh towels, or enjoy fresh sheets. I think that it is premature to lecture someone on the environmental impact of fresh linens, yet know nothing of the measures these people take when they are at home.
I live in a lake community and until recently never even owned a dryer. We are very careful about water useage, fertilizers and chemicals used, as well as cleaning products. Vinegar and baking soda are my most frequently used cleaning agents, over most commercial brands sold. My husband saves his baggie that his sandwich and cookies are in and uses it until the thing falls apart, my DGD uses reuseable bags and has asked my daughter not to buy any more plastics. We buy cups that we can use at all the coffee shops instead of paper and would rather choke than buy styrofoam. DGD is an environmental agricultural student, and planning on going to college for marine environmental conservation, taking after her grandfather in that she is a waste nothing, use what you take and reuse what you can person.
I do all of these things every day of my life. On vacation my splurge is sheets and towels, and no cooking. I am very contentious at home so that once in a while I can be selfish elsewhere.
