they just aren't right for it

maybe because they cant grow that far down into the earth

Maybe toxic metal is only found in Australia?

The trees could possibly be able to keep the gold down from their roots. Their roots and trunk are their strongest parts, so the roots might realize that the metal is bad for them, so they do the best that they can to keep the gold down. The gold might break through the roots, though, and that's how we get the 'gold leaves !' I know it may sound crazy, but trees are almost human! Why wouldn't they be able to keep the gold down?

I think some of the the trees are not in the gold place, or they are not deep enough.

I think some trees are able to avoid toxic because they have special edurance near the roots of the tree

People might take advantage of the gold now that they know it grows on trees. I think that there should be some sort of law saying that only Professional gold miners can get and use the gold. if anyone is allowed to get the gold, soon there would be no eucalyptus trees. that's bad for the environment. the enviorment is already going down because of all the trash.

omg like so cool like awesome

I guess money does grow on trees!!! Technically Lol :D

i think this is really cool too, and it also helps the environment too. AWESOME!!!!!! :) :) :D :) :)
