The information on Christianity comes from my background of the Bible. The information on Wicca comes from Scott Cunningham's book Wicca: A Guide for the Solitary Practitioner.
DISCLAIMER: Not all Christians or Wiccans believe in the same things. Looks like they do have something in common. :-)

Something should be said her about the way we see the Earth. While you maybe hard pressed to find a church organization that is actively involved in the conservation and preservation of our natural resources there is nothing in the Bible that supports the "who cares" attitude that most Christians have about the environment. The Earth is a gift from God. You shouldn't have to see it in black and white to know you should treat all gifts with care.
Psalms 19 1-4
The heavens declare the glory of God ; and the firmament shows his handiwork.
Day unto day utters speech, and night unto night reveals knowledge. There is no speech nor language where their voice is not heard. Their line has gone out through all the earth, and their words to the end of the world.
"All nature is constantly singing to us, revealing Her secrets. Wiccans listen to the Earth. They don't shut out the lessons that She is so desperately trying to teach us. We lose touch with our blessed planet, we lose touch with Deity." Scott Cunningham.
