"Planetary Boundaries" is a concept that defines the safe limits within which humanity can operate without causing significant harm to the Earth's systems. These boundaries include factors like climate change, biodiversity loss, and ocean acidification. Staying within these limits is crucial for maintaining a stable environment that supports life on our planet. Exceeding any of these boundaries can lead to irreversible damage, threatening ecosystems and human well-being. For example, if we surpass the boundary for climate change, it could result in extreme weather events and rising sea levels. Understanding and respecting these boundaries is essential for sustainable development and protecting our future.
