Welcome, Barak

"If we start with the assumption" we won't get anywhere.
But that's what it says; that we will have dominion and that we should tend.
Man does have dominion, but doesn't always tend.
People should, though ~ regardless of how they feel about the Bible.
.... Even today many believe that killing for the sake of killing is wrong, but killing in self-defense or for survival is acceptable.
I'd agree with that.
It seems we have become very destructive to our world and ourselves with the passing of time.
Yes, indeed.
Our efforts may be "too little; too late".
I hope not.
