This explains it pretty good I believe.

Conclusions:
The famine was not deliberate or man-made. It was caused by difficult weather conditions and the general backwardness left by tsarism in the country. As there exists no evidence of deliberate genocide, and the case relies entirely on the false assumption that the USSR kept exporting more and more food grain, completely disregarding the famine, I can confidently say that the holodomor has been debunked as a myth and a fabrication.
It is revealing to look at who the people spreading this myth are. In the 1930s they were the Nazi press & their American collaborators. In the modern era their work was carried out by cold-war anti-communists and far-right Ukrainian emigres. The myth is still widely propagated those elements, together with Ukrainian neo-nazis. The Holodomor myth is the work of Goebbels.
