The global population is now at 7.8 billion people. Will the earth be able to produce enough food and other resources to feed a growing population? Will the water resources be adequate?
Should the global population be allowed to grow to 10 billion, 15 billion or 20 billion?
With the current state of our technology, including agriculture, water and energy technology, we appear to be able to feed a growing population, and have enough to spare for emergencies.
We are not suffering any food shortages for the immediate future, except for the supply chain disruptions caused by the conflict in Ukraine.
However, some people argue that the population has already exceeded a sustainable level, and that the current population is causing challenges to the environment, climate and other forms of life.
It may be necessary to plan for a smaller global population to protect the environment. Maybe, a sustainable global population could be 5 billion.
This approach does not mean that we need wars and genocide to reduce the human population. Already, many people do not wish to produce children. It may be possible to plan for a smaller population, without making drastic changes to the preferences of most people.
We need a new mindset. We should not aim for more economic growth. Instead, we should aim for adequate production to meet current needs.
It also mean that people should be working less hours. They should not be competing for a bigger market share, or to acquire more wealth than others.
Life can be more meaningful, if people feel a sense of security and work to produce just enough for their needs. They will have more time to live a fulfilling life.
