the earth is our mother, we should learning respect for our mother

yes it is our Obligation. Thanks and God bless!

Maybe the word "obligation" carries too many current religion shame based connotations. And suggests another human trying to control others, part of the current problem.

We can experience the miracles and magic of life right now simply by becoming closer to nature and the earth.
My sense tells me without respect for our mother the earth, we cannot find true joy or happiness.

An earth/nature focused cultural paradigm is needed. Something ancient humans were aware of and has been lost by our modern culture consumerism and greed

obligation = responsibility

Yes of course,
I suppose I'm simply trying to point out how language like that, which is often used by politicians and clergymen, does precious little to enhance life, nature, and respect for mother earth.
I'm suggesting a cultural/social paradigm shift using words like "joy" ,"happiness" for the human representations of reality.
Over the past two millennia politicians and clergy have done precious little to respect our mother earth.
