What is the proper way to say "LOVE YOUR PLANET"?
I think Manutd is correct.
(i) love your planet was what i thought it was, but I think you meant Love your planet as an injunction to love one's planet. and that is 'ama tu planeta' .
as to your last question.
Ama tu planeta is correct. ama a tu planeta is not used although strictly speaking here, correct.
I am stuck between "Ama a tu planeta" and "Ama tu planeta". Do you know when to use which? Are they both proper'
I think 'Love your planet' is 'Ama tu planeta'
amo tu planeta
