It is very sad that something like this happens in a country where the majority are farmers, however at least people have to think about their daily food because they all have the right to live and plan their future, especially their income from agriculture, lest they be oppressed by people who irresponsible, if something like that happens then their actions are truly heinous, they should not think about themselves, there are still many people in trouble who they have to find a way out of.
The main role in this is the government in the country. I think every government in any country will always have good policies for its people, but the problem is that many people behind these policies are taking advantage of this situation by playing with the prices of every farmer. It's as if the government is turning a blind eye or it's very difficult to eradicate criminal mafias like this, indeed their actions are really cruel or greedy, they don't care at all about the fate of their farmers in the next life. The most important thing is that they can get big results and enjoy them. Not only in Nigeria but also in my country, the same thing happens, farmers always lose money and prices drop when the harvest arrives.
