Population growth threatens climate change, food security efforts: Expert

The world population is growing by approximately 74 million people per year, but this growth is not evenly distributed globally. With an estimated 7.3 billion people on earth, the population is one of many factors influencing the environment. 

According to a UN report, the world’s population is expected to reach 8.5 billion in 2030, and to increase further to 9.7 billion in 2050 and 11.2 billion by 2100 and projects that over half of that population growth would be mainly in the developing world and mostly in major cities. Several forecasts expect that number to decline due to climate change, insecurity, migration, decline in fertility etc.  Despite the economic gains of these rapidly-developing cities, they constitute a significant conundrum for governments like food security, health, and environmental pressure, further bolstered by climate change.
