Now that natural forest protection has been implemented and the Three North Shelter Forest has been established, why are sand and dust weather still intruding?

There are many reasons for the continuous intrusion of sand and dust weather, including natural factors and man-made factors. Although measures such as natural forest protection and the Three-North Shelterbelt have been implemented, factors such as climate change, human activities, and natural disasters may lead to the occurrence of sand and dust weather. In addition, the occurrence of sand and dust weather is also related to wind direction and climate changes between regions. Therefore, reducing the impact of sand and dust weather requires comprehensive consideration of multiple factors and the adoption of multiple measures, including strengthening environmental protection, controlling human activities, and strengthening meteorological monitoring and early warning.
