Question

sitive and negative effects of these modifications?
Using complete sentences, identify two ways humans in South and Southeast Asia have modified their water supply. What are the positive and negative effects of these modifications?

Answer 1

Answer:Modifications in South Asia, where almost 1.6 billion people live, are important measures to deal with urbanization and population growth. Research has estimated that almost 20 of 32 cities in India have water shortages on a daily basis. Residents of Kathmandu need to wait for hours to get water from the city. This modification helps with the control of water supply but restricts the amount of water to be used by the citizens.

Another South Asian government modification in Pakistan, hides vital information regarding water supply. Fort he government it is classified information, although there are treaties like the Ganges Treaty(1996) that supports the sharing of international information regarding hydroeletric. This is a measure that the Pakistan authorities consider critical for the control and benefit of water. But the lack of information sharing has also affected the government’s ability to deal effectively with natural disasters such as floods, earthquakes, and landslides .

Answer 2

Answer:

Humans in South and Southeast Asia have modified the water supply in two major ways. The first is by building dams and embankments to conduct flood management. People living in these regions found a need to control flood waters because they are faced with severe monsoons regularly. Many people live on the flood plains, so monsoons can become very dangerous. Dams and embankments can control flood waters and divert them away from where people live. However, when water is dammed or diverted, its natural flow is changed, preventing sediments from flowing naturally downstream. This can cause the rivers to flood other areas. People in South and Southeast Asia also use water supplies to conduct an activity known as aquaculture. This means that they control and grow seafood and marine products for human use. They create pens, dams, and nets to fence in areas of water where they can grow their products. This is beneficial because it can create a consistent food supply for citizens and an economic product that can be sold. Aquaculture can also have negative effects. For example, fencing in areas of water can change or even destroy marine animals’ natural habitats. Fishing is also an important way in which humans interact with their water supply. When humans fish, they can supply food for members of their population and create an economic commodity that they can export to other parts of the world. However, fishing can also have negative consequences. For example, when people overfish in certain regions, they can wipe out populations of fish and other marine life, which can decrease the biodiversity of certain animals. Boats can also cause water pollution, which can kill marine life and prevent the growth of coral reefs.
