Overpopulation
What is it?
• Overpopulation is an undesirable condition where the number of
existing human population exceeds the carrying capacity of Earth.
What causes it?
• Population growth results from the difference between births and
deaths the two visualizations below show how these two aspects have
changed since 1950.
When it turned up?
• Overpopulation has been rising continuously since the end of the Black
Death, around the year 1350.
• 200 years ago there were less than one billion humans living on earth.
• Today, according to UN calculations there are over 7 billion of us.
• For thousands of years, the population grew only slowly but in recent
centuries, it has jumped dramatically.
• Between 1900 and 2000, the increase in world population was three
times greater than during the entire previous history of humanity an
increase from 1.5 to 6.1 billion in just 100 years.
