The Future of Global Population: Too Many or Too Few?

TLDRThe world's population is currently over 8 billion, but it could decline to 6 billion by the end of the century. Declining fertility rates and an aging population are the main factors driving this decline. While some countries are facing population decline and labor shortages, others are still growing. The declining population can have both positive and negative impacts, including less pressure on resources but also potential challenges in healthcare and social care. Migration may play a role in filling gaps in the labor force, but anti-immigration sentiment is a concern. Overall, managing global population trends will require balancing various factors and finding sustainable solutions.
