Just like every expression of Life, Earth thrives in response to appreciation. True appreciation is not holding one thing in higher regard than everything else (as in worship), it’s the offering of attention toward whatever one finds pleasing from their individual point of view.
The mind may go on presenting thoughts about Earth being detrimentally unhealthy, how ‘other’ people are doing things to harm or destroy Earth, how Earth cannot sustain all resident life forms, etc. However, these thoughts are all forms of fear that disconnect your energy of awareness from the greater Truth, lead to counterproductive action, and carry no meaning except that which you give them.
There is no-thing in your world more powerful than your attention. To promote a healthy and sustainable Earth, simply look for what you can appreciate in nature and allow your senses to be enlivened thereby.
From this perspective your perception is infused with Love – the infinite creator and sustainer of all things deemed virtuous by you.
