In my opinion biofuel can be one of the alternative answers to fuel crisis, especially for the transportation. The way we make biofuel is what really matters. In many countries, biofuel is obtained from the conversion of food materials especially soya beans, corn, cassava, and sugarcane. Such practice will significantly reduce the amount of food supply both in the national and international market. Massive palm and sugarcane plantations in Malaysia, Indonesia and Brazil destroy bio-diversity of the local environment. Malaysia and Indonesia open millions of hectares of Sawit plantation for palm oil production.
In addition, the introduction of bio-fuel plant foreign to certain area will definitely damage the balance of food chain, and cause deforestation. For instance, I read in a book entitled Bahan Bakar Nabati (meaning literally bio-fuel) which says that Papua and West Papua province of Indonesia have the potency of 5,137,186 hectares of Sawit plantations (Elais guineensis) for the production of palm oil and bio-diesel. I consider it as unwise project. Sawit is not native plant of Papua. It comes from Africa. The introduction of sawit in Papua in the form of huge plantations will be harmful to the local environment especially the tropical rainforest. Actually there are a number of plants that are ready to be used for making bio-fuel. On the map, Papua island is located above Australia, it has tens of millions of Aren palm trees (Arenga pinnata) which are native plants. Traditionally, villagers tap the sap from very very small number of these plants to make alcoholic drinks whereas the rest majority are left untapped in the jungle. Local government have banned alcoholic drinks made of these plants since drunkards often committed criminal acts in the community. Less than one percent of the trees are used for making palm sugar.
The tapping of sap from Aren tree will not harm the environment because the worker does not have to cut any single Aren tree for 50 years which is its average life-time. Industrialized countries in Europe, The United States, Japan and South Korea must set special standard of biofuel imports. Biodiesel and bioethanol which are imported from third world countries must come from plantations that have caused deforestation of tropical rainforest and that are not directed for food production.
In fact, countries in Africa and Asia have a number of plants for bio-fuel raw material which are not food crops. Some of them are elephant grass, jatropha curcas; and to some extend Aren (Arenga pinnata) and Nypa (nypa fruticans). Both plants can produce 2 - 3 times more ethanol than sugacane per hectare.
I hope that this opinion will give a balance perspective on this bio-fuel matter.
