Lagos: The United Nations estimates that the world's population will reach 8 billion on Tuesday, with most of the growth coming from developing African countries.

Nigeria is one of them, where the resources are already at their maximum potential. In Lagos, which has a population of more than 15 million, people compete for everything from spots on crowded buses to electricity to light their homes, often traveling two hours each way. Some Nigerian children leave for school as early as five in the morning.

The West African country's population is projected to grow from 216 million this year to 375 million over the next three decades, according to the United Nations. As a result, Nigeria will have the fourth largest population in the world after China, India and the United States.

Egypt, Pakistan, the Philippines and India have dropped out of the list of countries with the fastest growing population. India is expected to overtake China as the world's most populous country next year.

Many families in Kinshasa, the capital of the Democratic Republic of the Congo, where more than 12 million people live, struggle to find and pay for affordable housing. Young children can attend primary school for free, but their chances depend on their parents' income.

According to Dr. Srinath Reddy, President, Public Health Foundation of India, the challenges of food security are increasing as a result of increasing environmental pressure, which is made more serious by climate change. "Our policy makers must focus on reducing inequality while focusing on climate change adaptation and mitigation."

However, experts argue that consumption, which is highest in developed countries that are not experiencing rapid population growth, poses a greater threat to the environment.

Poonam Muttreja, executive director of the Population Foundation of India, said evidence from around the world shows that a small percentage of the world's population uses most of the planet's resources and generates most of the greenhouse gas emissions. "Over the past 25 years, the richest 10 percent of the global population have been responsible for more than half of all carbon emissions."
