Humanity has already exceeded Earth’s limits, study warns
A new study indicates that humanity has surpassed Earth's sustainable limits, with a population of 8.3 billion straining ecosystems and resources. Researchers warn that continued growth and current consumption patterns threaten food security and climate stability. Solutions may include slowing population growth and altering consumption habits to mitigate long-term risks.
- ▪The global population is currently 8.3 billion, exceeding sustainable limits.
- ▪The study analyzed over 200 years of population and environmental data.
- ▪Researchers suggest that a sustainable global population is closer to 2.5 billion people.
