Historic moment for humanity: the reached today 8 billion people, the United Nations said known fact: mortality levels decline and life expectancy continues to increase. “This is an occasion to celebrate our diversity, recognize our common humanity, and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates,” U.N. Secretary-General António Guterres said in a statement. Population has doubled in the past five decades. It was 7 billion in 2011. Lower-middle income and low-income countries contributed the most to the population reaching 8 billion, officials said. Half of the population still lives in just 7 countries: China, India, the U.S., Indonesia, Pakistan, Nigeria and Brazil. Extreme poverty has declined and income inequality between countries has largely lessened over the past 25 years, according to the U.N.

The global population is projected to reach 9 billion in 2037 and 10 billion in 2058, signaling population growth is slowly declining. “Some express concerns that our world is overpopulated with far too many people and insufficient resources to sustain their lives. I am here to say clearly, that the sheer number of human lives is not a cause for fear,” Natalia Kanem, executive director of the U.N. Population Fund (UNFPA), told media. There are other big concerns. Climate change continues to pose one of the biggest threats to humanity. International aid agencies have recently been struggling to find enough resources to deal with multiple conflicts and crises at once.
