A global catastrophe refers to a significant event that causes widespread destruction and disruption across the planet. This can include natural disasters like earthquakes, tsunamis, and volcanic eruptions, as well as human-made events such as nuclear war or pandemics. The impact of such events can lead to loss of life, economic instability, and long-term environmental damage. These catastrophic events often require international cooperation for response and recovery. Organizations like the United Nations and various non-governmental organizations play crucial roles in providing aid and support to affected regions. Understanding the causes and consequences of global catastrophes is essential for improving preparedness and resilience.
