Why are We Worry with Human Extinction? - Science 29

Human extinction has been discussed since many decades ago, and even lead to worry in recent days.

The fact that our world just reaches 8 billion people this year. This number is projected to increase in coming years.

World population is projected by United Nation (2022):

- in 2030 hit 8.5 billion people
- in 2050 reaches 9.7 billion people
- in 2100 hit 10.4 billion people

So, why are we worry with human extinctions?

Yes, population seem increasing year by year, but it will reach peak in 2100. Since then, world population is expected to decrease.

We are witness decreasing population in many countries such as Japan and South Korea. No growth in China anymore, population will decrease next several years.

Moreover, in term of biology, surprisingly, men sperm production is decreasing since decades ago:

- between 1973 to 1999, about 1.2% reduction of sperm count per year
- since 2000, about 2.6% reduction of sperm count per year

Acceleration of sperm reduction has been occurred all over the world. If this trending continue, human extinction is highly possible in the future.

  5. O homem é o principal causador das alterações climáticas, e, por consequência o seu destruidor.
    O ser humano tem que saber cuidar da sua casa comum. O Planeta Terra.
