Could you correct my mistakes, please? :) Experts for many years assumed that the human population grew quite surprisingly. However, the speed of this growth might be surpising after that. According to the report that published in Population Reference Bureau, world population will reach 9.9 billion as of 2050. Almost 7.6 billion people live in the planet at today. In that case, when we apply mathematical rules, we can predict that universal population will be more %33 than today over the next 35 years. This estimate is bigger than the report that prepared based on current data at United Nations assumed that our population will be reach 7.6 billion people at 2050. There are a few different reason about why world population is growing so fast of course. One of them is people are as long-lived as they have never been throughout the history because of the progress in access to health, nutrution and food. In the United Nations report, it is also mentioned that the number of people who at reproductive age is increasing and immigration is increasing to more developed areas. Thanks in advance for correction :)
