Global population growth is a concern as it leads to increased strain on natural resources and pollution. By 2050, the world's population is expected to grow by 2.5 billion, mostly in developing countries. This growth means more energy consumption, more vehicles, and more pollution. Natural resources like minerals, land, and forests are crucial for trade and production. Human resources play a key role in production as well. Balancing population growth with available resources is essential for sustainable development.
