Question

Minamata disease, a neurological syndrome with symptoms including ataxia, numbness, general weakness, narrowing of vision and damage to hearing and speech, and even insanity, paralysis, coma and death within weeks, is caused by severe poisoning by what?

Answer 1

Slow implementation of land and labour reform
Serfdom had been abolished in the Estonia area (then part of the Russian Empire) in 1816, but full implementation and reform in land ownership was slow in coming. The peasant revolt on the Mahtra estate and the action to crush it are thought to have significantly influenced the work of the committees working on emancipation of the serfs in Russia itself.
