Question

Write a scientific explanation that describes total world carbon emissions in 2050 if the world’s population decreases to five billion people.

Answer 1

In 2050, if the world's population decreases to five billion people, the total world carbon emissions can be estimated based on the current rate of increase in CO2 emissions.

Step-by-step explanation:

In 2050, if the world's population decreases to five billion people, the total world carbon emissions can be estimated based on the current rate of increase in CO2 emissions. Currently, the increase in CO2 emissions since the time farming began is around 50,000 fold. If all populations around the world had the same intensity of technometabolism as developed countries, the increase in CO2 emissions would be similar. However, it's important to note that these calculations are based on certain assumptions and projections, and the actual carbon emissions can vary based on various factors.

Answer 2

Step-by-step explanation:

The current world population of 7.6 billion is expected to reach 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion in 2100, according to a new United Nations report being launched today. With roughly 83 million people being added to the world’s population every year, the upward trend in population size is expected to continue, even assuming that fertility levels will continue to decline.

The information is essential to guide policies aimed at achieving the new Sustainable Development Goals.
