When will this Earth be empty?

If the estimates made by scientists and the United Nations are correct, then after 100 years, we will have no place to live.

At the end of this year, the world population is estimated to reach 7 billion, just 12 years after we reach the 6 billion mark. But how big will this small planet be. Can we continue to grow to infinite or will we reach a climax? According to current calculations, we will reach the maximum milestone in population in 2050 then gradually decrease. Specifically, the United Nations estimates that the world population will reach 9 billion in the next 40 years, ie around 2050. It is hard to believe that it only takes 12 years to increase by 1 billion. but it will increase by 2 billion more until 40 years later.

The world population at the end of 2011 will be 7 billion people.

However, the above statement is entirely based on the current trend. Developed countries now tend to have a negative population growth rate and it is strongly affecting many countries in South and Northern Europe, promising to expand to many more countries. Therefore, according to scientists, once the 9 billion figure is set, the population will increase to 9.5 billion and then begin to slow down. According to this model, there are still two areas with positive population growth rates, Africa and South Asia.

One of many predictions about the world population.

But what will happen if the above trend does not apply worldwide? Then perhaps the human population will reach the 11th digit (more than 10 billion people). People have estimated this by Thomas Malthus's rule (if the growth rate is 1%, then the original number will double every 70 years). In fact, there are many things affecting the world population in the future, in which, science and technology plays a very important role. People are getting closer and closer to the threshold of 'not forever young' . Let's talk about immortality, just adding 20 to 30 years of life is enough to create minor problems in society and economy.

There will come a time when the Earth will no longer "carry" anymore.

The predictions including the calculations surrounding the development of science and technology show that we can absolutely reach the milestone of 14 billion at the end of this 21st century, double the current and that is extremely danger. The present Earth certainly cannot afford enough space for each person to live together without a great step forward or a social or technological jump. Now all we can do is . predict.
