A tree that bleeds metal

Imagine doing a little genetic tinkering to produce a tree that bleeds gold or platinum. Although I _am_ wondering if the three could incorporate enough metal to make increased lightning strikes a survival issue.

Just googling and that is exactly what some scientists are trying to do.

Why does no one ever talk about these with respect to Mars? It seems like a research-worthy pursuit to see if we can engineer plants (bacteria?) like this to modify the climate of Mars, or to make artificial superstructures self-sustaining.

Shouldn't it be a research-worthy pursuit to modify(fix) the climate of the planet we're already living on? I'm not sure what attempting to live on a desolate planet is going to do for us. Say we turn it into another Earth, now what? We ruin that one too?

We should research stabilizing our climate. Absolutely. But while we are at it, it would also be in our interest to make humans a multiplanet species, in order to protect us from a global extinction threat that isn't man made, as well. Super volcanoes, calderas (pretty much the same, I know), large meteor strikes.... none of these have anything to do with man made pollutants, and survival of the species is kind of a neat little concept, in my opinion =) Granted, we would probably become a new species in several thousand years, once we were off planet, due to the radiation and gravity differences, but hopefully the problem solving and intelligences would remain.

Earlier quoted context omitted.

It's a different scale. Human blood is well under 0.08% iron, this tree has 25% nickel. So over 300x as concentrated. PS: 4 grams of iron in a persons body, ~5kg of blood.

The hemoglobin molecule itself only has something like one iron atom per 1000 non-iron atoms.

Yea it's: C2952 H4664 O832 N812 S8 Fe4 so 2315:1.

Humans bleed metal too; there's iron in haemoglobin.

It's a different scale. Human blood is well under 0.08% iron, this tree has 25% nickel. So over 300x as concentrated. PS: 4 grams of iron in a persons body, ~5kg of blood.

The fluids also contain various electrolytes, i.e. metal cations. But still nowhere close to those trees.
