What was this major problem and how did it Arise?

The major problem was a significant increase in climate change-related disasters, such as wildfires, floods, and hurricanes. This issue arose primarily due to human activities, including deforestation, fossil fuel consumption, and industrial emissions, which led to higher levels of greenhouse gases in the atmosphere. As a result, global temperatures rose, disrupting weather patterns and intensifying natural disasters. The cumulative effects of these changes highlighted the urgent need for sustainable practices and policies to mitigate climate impacts.
