Yes...as a matter of fact you can farm chemically polluted land...certain plants pull toxins and heavy metals from the soil...and there are several natural materials you can use to neutralize the soil...as far as money curing the sick...that's the single dumbest thing I've read in my entire life...there is no profit in a cure for anything...which is why pharmaceutical companies come up with treatments...if they cured you, you'd stop coming to see them...but if they treat you, they can drain your bank account until you die...and finally, if they knew how to do the things I mentioned, there wouldn't be a hunger problem...not to mention, we wouldn't have to spend money clothing and feeding them...the fact of the matter is...they do NOT know how to do any of the things I mentioned...they've NEVER been taught...in fact, they've been trained to rely on failed infrastructures and government handouts...but far be it from me to try and educate those who are incapable of conducting a modicum of research...
