Both movements were based on formation of countries that are Muslim, and they were done in a military manner with violent clashes.
Explanation:
Pakistan and Bangladesh have traditionally been part of India for thousands of years. This changed when the British Empire granted independence to its South Asian colony and instead of keeping it whole it divided it, initially in two parts, later it turned out to be three. This happened both because of what was thought to be the best for the stability of the region, but also because of propaganda and movements from the Islamic world.
Unlike India, Pakistan and Bangladesh were predominantly Muslim, so in order to avoid internal conflict the British decided to partition India in accordance to religion. While this seemed that it would contribute to avoiding problems and conflicts it turned out to be the opposite.
The Indians were not happy with this and acted aggressively to the loss of territory. The Islamic movements in Pakistan and later in Bangladesh also acted aggressively. This led to large scale conflict, with millions of people ending up dead or homeless, and there was a large scale persecution based on religion.
Natural Hazards can be described as dangerous occurrences that are a threat to human survival. These can include unforeseen sudden events such as earthquakes, volcanoes, Tsunamis and tornadoes. This can also include some slow-moving disasters e.g. droughts, climate change and even diseases.
All these events are difficult for humans to adapt to. Human bodies have not gone through an evolutionary process where we can coupe with such disasters.
In modern countries, some precautions have been developed e.g. dams to store water in times of drought or earth-quake proof buildings seen in Japan.
Generally, humans in poorer countries are more susceptible to natural hazards due to poor infrastructure.
To stop the environmental disaster. Deforestation of the Amazon is bad news.
