When people draw up budgets for their living expenses, they sometimes distinguish between necessities and nonnecessities, or between essential expenditures and nonessential expenditures. After paying for the necessary items, the person working within the budget may view the remaining funds as disposable income, and the things that he or she purchases with some or all of that leftover money may be termed (in a reasonably professional way) discretionary items.

Someone compassionate cares for other people and perhaps for animals (but not, I think, for single-celled organisms or plants, so not all living things).

Someone who feels an emotional connection with other things can be described as empathetic. Such a person can be called an empath.
