I guess back in 2012, none of the scientists thought of a highly contagious plague to solve this problem.
Scientists: ‘Look, One-Third Of The Human Race Has To Die For Civilization To Be Sustainable, So How Do We Want To Do This?’

WASHINGTON—Saying there’s no way around it at this point, a coalition of scientists announced Thursday that one-third of the world population must die to prevent wide-scale depletion of the planet’s resources—and that humankind needs to figure out immediately how it wants to go about killing off more than 2 billion members of its species.
Representing multiple fields of study, including ecology, agriculture, biology, and economics, the researchers told reporters that facts are facts: Humanity has far exceeded its sustainable population size, so either one in three humans can choose how they want to die themselves, or there can be some sort of government-mandated liquidation program—but either way, people have to start dying.

“The longer we wait, the higher the number of people who will have to die, so we might as well just get it over with,” said Dr. Chelsea Klepper, head of agricultural studies at Purdue University, and the leading proponent of a worldwide death day in which 2.3 billion people would kill themselves en masse at the exact same time. “At this point, it’s merely a question of coordination. If we can get the populations of New York City, Los Angeles, Beijing, India, Europe, and Latin America to voluntarily off themselves at 6 p.m. EST on June 1, we can kill the people that need to be killed and the planet can finally start renewing its resources.”
Thus far, humanity has been presented with a great variety of death options, among them, poisoning the world’s water supply with cadmium, picking one person per household to be killed in the privacy of his or her home, mass beheadings, and gathering 2.3 billion people all in one place and obliterating them with a single hydrogen bomb.
