I cannot answer that question, but I can state with certainty: thinking we must show our love by enforcing often wrong and misguided standards of environmental "good stewardship" on others, individuals or whole nations, is solely an exercise in vanity.
You ask the wrong question when you frame it in terms of "how can we show love," because you presume to ask it for me. I already have my answer, thank you. See my tagline -- that "personal relationship" -- Psalms doesn't talk about His word as a lamp unto our feet, but mine.
Serving God is a personal business. When government presumes to do it for "us," amoral tyranny results.
Who is talking about forcing anybody to anything?
The whole point of the quotation was to show the need to feed the poor and to cherish and protect what God has given us.
Nobody said anything about governments.
