One cannot be grateful for their 'stuff' without giving thanks for the earth from which all is provided.
I am grateful for the earth's crust which is the place I know:
Dense green forests decorated with colorful creatures and plants;
oceans of green and blue, teaming with life in their depths;
vast, undulating silica landscapes hiding their swarms within the tans and browns;
bright and white of snow covered ground visited by very few.
All this and the places in between: Where water meets land, where frozen is melted, where life refreshes in a storm and where it ends between a predator's jaws, the earth supplies our potential for life, healing and joy. Each generation removes a little more than the last; each human pressing for their requirements until seven and a half billion lives demand from this earth their needs and some, their desires. Earth is left wounded and unable to recover without help under the increasing pressure.
I am grateful for living while I am still able to enjoy her beauty and bounty. For this earth I give thanks.
