First I met a Christian who believed that God had created humans to live in a paradise on Earth, Eden. It was God's wish that people should live that way, without ruining the paradise and rebuilding it with all their ability if it once had been lost. That was what life according to God's wishes meant.
So we did agree: paradise on Earth was the very best option!
I met also a Muslim and things worked out the same way:
A global paradise is the best!
The Buddhists search for an unending happiness in this life and seek to help all the other living beings to the same goal too.
So the thought of working for a global paradise for all fairly sounded really nice in their ears!
Since I had been dreaming of a paradise on Earth all of my life, I had quite a good picture of what the paradise would look like. It would be a global nature paradise like in the beginning of time with all the nature undisturbed by human hand, just like the nature protectionists wished for. So the next group was clear:
