As of 2023, the estimated population of Earth is approximately 8 billion people. This significant milestone reflects global population growth, which has been driven by factors such as improved healthcare, advancements in agriculture, and increased life expectancy. However, this rapid population growth also presents challenges, including resource depletion, environmental degradation, and the need for sustainable development. Countries around the world are addressing these challenges through policies aimed at family planning, education, and healthcare services to ensure a balanced approach to population growth in the future.
