I have switched to reusable mugs, but could be even better with using them more frequently.  I do occasionally buy coffee and get singe use coffee cups (I make sure to recycle them) but could buy a reusable mug from that particular location and request to use my personal mug.  It makes me feel like I am using resources wisely, reducing trash, and picking out fun reusable mugs helps.

I practice self care by eating right, exercising, trying to avoid and handle stress the best I can, spend time with friends and family, enjoy hobbies, and practicing my faith. 

Energy is generated by electricity where I live and I know this impacts the environment in a negative way. I live in an apartment building where a lot of the units face each other. I can see that there are a good number of people who leave lights on continuously through the night in their entire apartment (a four-room space). It makes me think of my dad who would always say, "Are you paying the electric bill?" if I didn't turn a light off after leaving a room. 

I have to wonder why it is that my fellow apartment dwellers leave all the lights on ALL NIGHT. Why does their entire space need to lit? How can they possibly be in all four rooms at once? This has to have a negative impact on the environment because it's just a waste of energy.

Most ecosystems fluctuate within a range of tolerances where higher levels of one resource or force push balancing levels in other areas. When a new factor or force is introduced, it can take awhile for the system to achieve it's new balance.  Making wise choices about consumption helps preserve that balance instead of using up resources that become unavailable.
