It seems to me that the earth is the very embodiment of bodhicitta - she unconditionally provides the grounds for life and no matter who we are or what we have done, we equally receive compassion from her. It is quite amazing when one thinks about it - that there is oxygen which we can breathe, that there is water which we can drink, and that there is soil on which plants can grow to feed us.

It is very important that we emulate the earth's attitude of generosity towards us. Just as we would do when receiving a precious gift from someone we love, we need to nurture what we have been given. This includes the earth's many wonders and biodiversity, as well as our relationship with all sentient beings. ... If we are able to do this, we will no longer simply be a burden upon the earth but will be a source of relief.

~ The 17th Karmapa, Ogyen Trinley Dorje, from 'The Seed of Compassion'

Shallow ecology is anthropocentric, or human-centred. It views humans as above or outside of nature, as the source of all value, and ascribes only instrumental, or 'use' value, to nature. Deep ecology does not separate humans - or anything else - from the natural environment. It does not see the world as a collection of isolated objects but as a network of phenomena that are fundamentally interconnected and interdependent. Deep ecology recognizes the intrinsic value of all living beings and views human beings as just one particular strand in the web of life.
