Since science and technology seem to create as many problems as they solve, should we instead try to bring the world back to the harmony that characterized Eden ?.
The spiritual idea was that we are in a big circle headed back that way, actually. Read the description of the Garden in Genesis, then the description of Heaven in Revelation and take note of the similarities. The only main differences will be the presence of clothing and buildings, which are the by-products of our long cycle through this mortal life.
