On October 31, 2011, the world's population reached 7 billion people. Some countries celebrated this milestone, while others viewed it with concern due to the environmental and resource strain of continued rapid population growth. The population is projected to reach 8 billion by 2025 and 10 billion by 2100. Many worry that the population is growing most in poorer countries that have fragile environments and limited resources to support more people. Solutions proposed include increasing access to education for women and family planning services to slow population growth rates.
