The world’s population continues to grow rapidly

The world’s population has benefited greatly from years of disease eradication and no world wars in nearly 70 years.

However, that also means that the planet will have to house and feed more people. The United Nation on Thursday forecast that the planet’s population will increase to 8.1 billion by 2025 from today’s count of 7.2 billion people.

Most of the growth will occur in the developing countries and more than half in Africa so that by 2050, the Earth will have 9.6 billion human beings — 8.2 billion of them in developing regions. Developed countries’ population will only be 1.3 billion.

But that kind of people explosion raises concerns about planet resources. People in developing countries already want to have U.S. energy, food and other consumption habits, which far surpass this country’s share of the population.

The planet may not be able to sustain the population growth that is projected unless technology and science develop new methods of doing so — again.

The world’s population was about 5 million at the start of agriculture about 8000 B.C. By 1 A.D. the population grew to about 200 million people.

It had taken most of human history for the population to reach 1 billion people by 1800; the 2 billion mark was hit by 1930, thanks to the industrial revolution.

The world hit the 3 billion mark in 1959, and by 1974 the planet was supporting 4 billion people. The rapid growth resulted in 5 billion people by 1987 and 6 billion people in 1999.

Keep in mind that as the human population expands, other species are going extinct because of what so many humans are doing to the planet — that includes global warming.
