they should take his wealth to rebuild the trees,
if he works take his money compleatly until it is repaid just leave him food and from time to time clothes
if he does not work he is forced to work
if he complains or it is too much damage take money and walth from his parents, from his brother and so on..
if he goes dont give him a passport but take land wealth and so on from his parents, brothers and so on...
without getting the money back mentality and without real punishment for him and his relatives they will do it again and again.. we are not dealing with normal people here
