A Modest Proposal

As many of you may know, the human race just passed its 7 billion mark this week. Truly, this is a great feat. However, it is as dangerous as it is amazing. Think about overpopulation. There are certainly not enough resources to sustain seven billion people, as even with 6 billion people oil and other energy sources were becoming scarce. Think about the food situation. Now, as a planet, we have seven billion mouths to feed. Considering that a very small percentage of land is actually arable and that much arable land is not used, there will be great difficulty in preventing many people from starving. Furthermore, the amount of fuel usage will increase greatly, causing two more problems: one, the diminishing of oil reserves and coal reserves, and two, the increasing of greenhouse gases, causing our planet's heat to skyrocket.
It is with this realization in mind that I propose a solution to our worries.
All people should be given sufficient population control restraints. Schools should teach children about proper contraceptive use, so that, when such a time arrives as they would need to use the contraceptives, they will be thoroughly prepared. Further precautions may be taken in the case of a family having more than two children.
Furthermore, I believe that homeless people can be used as a food source. They are unable to contribute anything to society, as the majority of them do not have jobs. They are taking up space on the streets, and are, in effect, useless. Killing them to process them into food would serve a greater purpose in keeping other people with a potential future alive. Certainly, if the homeless people knew that, by dying, and ending a life of misery and pain, they could bring sustenance and joy to other human beings, they would, I am certain, give up their lives freely. It would, unfortunately, be too difficult to take the time to explain this to them. Therefore, it would be prudent to just kill them, and send a letter to their next of kin, explaining the situation. (Furthermore, the letter should explain that, if their next of kin had taken care of them, the homeless person would not have been in such a situation, and the blame falls squarely on their relations' shoulders.)
A further point that could be carried out in order to reduce the population is the production of anthrax. I realize that many people may be against this, under the grounds that it may kill people, but, unlike many other forms of lethal weaponry, anthrax is not something that kills due to prejudice against another's race or sexual orientation. It is, in effect, a thoroughly egalitarian killer! Furthermore, the second amendment guarantees the right to bear arms, a right which members of the NRA constantly parrot. These arms, mainly guns, are most commonly used to kill people. If that is the case, then why can't anthrax, which does the same thing, be protected under the second amendment?
