If we believe we are separate from God, and from one another, we can easily accept that we are separate from the earth.  When we swallow the lie that we are separate from God's creation, it makes it possible, easy even, for us to pollute the air and poison the water as we have been doing at an alarming pace.  When we become separated, we fall prey to the egocentric mindset that is solely concerned with turning a profit, leaving behind a mess for the generations not yet born to inherit.
 
Many Christians, and people in general for that matter, are not yet environmentally conscious because we adhere to the fallacy that the earth is not our home and that we are just passing through the earth.  The earth is the Lord's, and the earth is ours and the earth is us.  Recycling, conservation and minimalist living are not perceived as burdensome once we realize our connectedness to the earth and all of its creatures.
 
When we sense this oneness, we will gladly lend a helping hand  because we will realize that we are saving our own lives! We make a brighter day when we see ourselves in the faces of others; in the faces of our enemies; when we see God in all of His creation.  When we accept our connectedness to creation, we awaken to the idea that we are only encountering ourselves, in others and in everything.
