Response in English: Over the past 100 years, the world population has experienced significant growth. At the beginning of the 20th century, the global population was estimated at 1.6 billion people. Since then, it has grown rapidly due to several factors, including advances in medical science, improved sanitation, and greater availability of food.In the 1950s, the world population reached 2.5 billion, and by the end of the century, it had more than doubled to 6 billion. As of 2020, the world population is estimated to be around 7.8 billion. This exponential growth rate is expected to continue, with predictions that the global population will reach 9.7 billion by 2050 and 11.2 billion by 2100.This significant increase in population has resulted in numerous challenges. As the number of people on our planet grows, so too does the demand for resources such as food, water, and energy, which puts a strain on the environment. Additionally, population growth has led to problems such as overcrowding, deforestation, and pollution.In conclusion, the last 100 years have seen a dramatic increase in the worlds population due to advancements in various fields, and this trend is expected to continue. However, this growth presents significant challenges that require innovative solutions to ensure a sustainable future for all. .
