Pesticide ban helped to decrease suicide in South Korea by 15%

South Korea has the highest rate of deaths by suicide in the developed world. While suicide rates across the developed world have fallen or stayed stagnant the past decades, they've rapidly increased in South Korea. In 1995, there were 12.7 deaths by suicide per 100,000 people in South Korea. That number reached 33.3 by 2010. Since 2010, however, suicide rates in South Korea have fallen. The banning of a highly-toxic weed killer called paraquat has been key in plummeting suicide rates.
