As Christians, we are to till and keep the garden… not use and abuse it. If we do not care for creation, creation will not care for us. To ignore our responsibilities to care for the earth is not just a foolish and short-sighted thing to do, it is a blatant affront to God’s original intention for our lives. Today our decisions and actions take on global importance as our human footprint covers more and more of the earth. If Christians are to be true to God’s original purpose for humanity, then it is Christians who should be on the forefront of efforts to care for this garden we call Earth.
For an introduction on the topic I would suggest Introducing Evangelical Ecotheology by Dan Bruner, Jennifer Butler, & A.J. Swoboda.
