The mass destruction of girls has produced a systemic gender imbalance in whole populations for example; there are more unmarried young men in China than the entire population of young men in America.
The Stop Gendercide Now Campaign consists of a public awareness campaign and a petition to put pressure on the governments of countries with significant sex ratio imbalances:
To introduce measures to ensure that the killing, fatal neglect or abandonment of baby girls because they are girls is ended.
To carry out and publish an annual audit giving the sex ratio, the measures put in place to address it, and the progress or otherwise of these measures.
