To those who say that the rock ash isn't toxic:
I've seen pictures of land without the rock ash and with it, and there's a clear difference. Clearly, rock ash contains toxic materials that degrade the land. Here's one article:

The material is highly acidic (pH lower than 2.1) and consequently does not allow for life to thrive. The US Geological Service says that it is usually associated with lead, molybdenum, silver, copper, and antimony. It also contains sulfur compounds that are volatile (they can easily become gaseous) and may cause low-impact acid rain. In any case, I agree with what many say about the material being sent to a country that has nothing to do with who created the waste material. If people protested against this action, it would be reversed.
