Reducing the Amount of Plastic We Use?

As we all know, the amount of plastics produced, purchased and ultimately discarded is vast. In one house alone the number of platic items used in virtually every aspect of home living is astronomical. Many plastics are bad for people's health, as well as being bad for the environment during production, and after the fact in the form of litter. It seems almost impossible to avoid plastics, but do people here have any input on how one might go about reducing the amount of plastic that comes into a home?
