A growing population can generate economic growth
The birth of more people means there will be a great number of parents investing in their youth.
Increased purchases of products and services such as food, clothing, education-related expenses, sporting goods and toys feed the economy.
Parents purchase large homes to make room for their children.
The large homes that parents with children purchase feed the construction industry economically.
Children then grow into adults who work for pay and spend it in the economy.
Medical, agricultural and industrial innovations
People will be forced to come up with new ideas and ways of
doing things.
Diseases, food shortages and pollution (all disadvantages) are
problems that we will be forced to solve.
With humans constantly reproducing there is no way for the
human race to go extinct.
With a larger population there is more human innovation.

Food resources are limited and the population may grow
beyond sustainability.
People who become desperate for food and land so they
may get into organized crime for money
More people will buy cars which will create more air
pollution. and will create more waste and landfills.
These disagreements can escalate into a huge amount of
conflict or even wars.
- With a large population it takes a lot to control a
situation like a war or a riot.
- It would be almost impossible to keep even temporary
peace.
Conflict and War
If all people in the earth consume like SaudisWe will need 7 times resource more than our planet
