@dailymail: A new study has reignited debate over whether Earth can sustain its rapidly growing population in the long term. Writing in the journal Sustainable Development, researchers argue the global population may need to gradually decline to around four billion by the year 2200 to reduce pressure on the planet's resources and ecosystems. The team says the shift could happen through voluntary measures such as expanding access to family planning, rather than any sudden reduction in population. #science #population #earth #sustainability #family
