Question

Explain a positive and negative effect of desalination using this text and only the text

Desalination is the process of removing salt from seawater. In Middle Eastern countries, like Kuwait, water towers and tanks are used to store desalinated seawater for city and personal use. The desalination process is expensive and requires a lot of energy. Oil and gas is used to power the desalination plants. The process can also create problems for the environment. For example, the salt removed from seawater is often dumped back into oceans where the increased salt levels affect the ocean's environment

Answer 1

A positive effect of desalination is that it provides a crucial source of freshwater for cities and personal use in arid regions, such as those in Middle Eastern countries like Kuwait, where water scarcity is prevalent.

A negative effect of desalination is that the process is expensive and requires significant amounts of energy, often sourced from oil and gas, which can lead to environmental issues. Additionally, the disposal of the excess salt back into the oceans can negatively impact marine ecosystems by increasing salt levels.
