生产液体燃料的生物乙醇需要像甘蔗和玉米。这些作物正在越来越多地用于生产生物乙醇。这里而不是使用玉米等作物生产生物乙醇,它可以被用于喂养穷人。这些作物是供人类食用。仍有庞大的人口死于饥饿的世界。有很多贫穷的国家,人们没有足够的食物。因此是没有意义的世界使用的作物生产生物燃料而不是提供给人们遭受饥饿。如果所有的人在这个世界上有足够的食物然后决定生物燃料的粮食作物可能是一个明智的决定,但因为有一大部分人口遭受饥饿,使用粮食作物生产生物燃料没有意义(Guinee Heijungs &范德沃特,2009)。
Biofuel provides a renewable source of energy and also does not harm the environment. However there are ethical issues in using biofuel as an alternative source of energy. There have been criticisms from different organizations on usage of the crops to produce biofuels. Serious questions on the food security, food prices, and human rights are being raised by governments and different organizations.
Biofuel conversion requires plants and crops. This usage of crops raises a significant question whether it is advisable to use crops which can become food for the people suffering from hunger. This is one of the most ethical issues in using crops to produce biofuel. Several people from institutions like United Nations have spoken very strongly on the increased usage of the crops in producing biofuel.
Production of liquid fuel like bioethanol requires crops like sugar cane and corn. These crops are being increasingly used to produce bioethanol. Here instead of using crops like corn for production of bioethanol it could have been used for feeding the poor. These crops are meant for the consumption by humans. There is still a large population of the world which dies of hunger. There are many poor nations where people do not have enough food. Hence it does not make sense for the world to use the crops to produce biofuels which instead could be fed to people suffering from hunger. If all the people in this world had sufficient food to eat then the decision to make biofuel out of food crops could be a sensible decision but since there is a large section of population suffering from hunger, usage of food crops to produce biofuel does not make sense (Guinée, Heijungs & van der Voet, 2009).
