All of Earth’s Water in a Single Sphere
“This picture shows the size of a sphere that would contain all of Earth’s water in comparison to the size of the Earth. The blue sphere sitting on the United States, reaching from about Salt Lake City, Utah to Topeka, Kansas, has a diameter of about 860 miles (about 1,385 kilometers), with a volume of about 332,500,000 cubic miles (1,386,000,000 cubic kilometers).”

All the water in the oceans, in every lake, river, stream, all the water in every person, and the water in the atmosphere, even the water in your tomato plants and pets is contained in that blue dot. That’s it. Our lives exist in a precarious balance on this earth that our good God has provided for us.
What is a disciple’s responsibility related to conservation of resources on the gift God has given?
