I believe that God has called us to be good stewards of our Earth. I also believe that most people fall seriously short of fulfilling this command, including Christians. There are so many things one can do to help our environment.
Recycle, reuse, and cut back.
Put trash in one container, paper in one container and plastic, glass, and steel into another container. Compost food and yard waste.
Use cloth bags at the store or reuse old plastic bags. Don’t throw out “disposable” containers, wash them. Use washcloths or towels instead of paper towels.
Turn off lights not used. Use energy saving appliances and light bulbs. Hang clothes instead of using a dryer. Keep the thermostat at a lower temperature and put on more clothes.
These are just some ideas among the myriad ways one can be a good steward.
