Is a perfect world possible?

Imagine you are in the year 1798 and you are Thomas Robert Malthus. The Industrial Revolution in England has only begun a couple of years ago in 1785. Malthus argued in his essay, "On Population" that a perfect world isn’t possible due to the Earth being a set size and the population increasing constantly.
Now, imagine you are Malthus and you have somehow been transported to today, the year 2013. How would Malthus react? More importantly, do you think his argument would change at all? Can an imperfect world become perfect?

No way. I don't think that this world can be perfect. One way like in the movie the moment of self realization will be helpful. and thus the world or corresponding area will be changed. If one can make this happen in the world then there is no way that this could even be possible because not every one in this world can be convinced.

It is impossible to create a perfect world. And it is not because of this or that. God already did it.
