Earth, Ethanol, Homo Sapiens and Roaches

Earth I posted a comment to respond Sutono’s post. He mentions his opinion about world’s economics vs the earth. And in the end, he posted simple questions:

Then the question, how long can the world economy keep growing? Or in other words, when will our earth fail to feed us?

Hardono mentions a thing about ethanol to replace fossil fuels. So I came out with my opinion which is a respond to Sutono and Hardono’s:

———————-

Few things about using ethanol as fuel which was highlighted in the economist and I think that ideas are somewhat true (I’ll try to summarise as accurate as possible):

There was a study to calculate the cost (to the environment) to process corns (the main ingredients of ethanol) to ethanol. The result was surprising. If I’m not wrong, the total cost to the environment is almost the same or more than the fossil fuel
By processing corns to ethanol, there’s a shortage of supply of corns for consumption. Thus, the price of corns is rising which hurts the end customers

So, in my opinion, there’s still much to do to replace fossil fuel to ethanol. One of the examples is how to improve the process of producing ethanol from raw materials without hurting the earth too much.

What about hydrogen? Hydrogen + oxygen = water ^_^. But I’m not sure the process of extracting hydrogen.

I think, earth won’t fail to feed us. One thing about human which fascinates is that, our body is the result of optimisation for millions of years.

Maybe when one day the earth fails to feed us, there will be a new organism which is going to dominate the earth, replacing Homo Sapiens. Or we evolute to a new form .

And if it’s caused by nuclear war, as far as I know, the species which has better resistance to radiation than human is: COCKROACH. It’s time to imagine how cockroach will dominate the earth, or we evolute into a cockroach-like creature =P.
