Why are so many natural disasters taking place within June to September ?

Extreme weather events such as landslides, floods, and waterlogging have become more common in the last five years. The primary cause of these climatic abnormalities is the congestion or clogging of the drainage network of a watershed, either natural or artificial. The human body's arteries or blood vessels can become clogged due to the buildup of fats, leading to potential health issues such as backflow, ruptures of blood vessels, and blood spills.

To mitigate the frequent occurrences of flooding, waterlogging, and landslides, it is essential to desilt and expand our drainage system. By desilting the existing network, we can clear blockages, and by expanding the network, we can provide an additional path for excess water to flow. However, governments have turned blind to such proposals.

To solve this problem, we need to desilt and expand our drainage system.
