Explanation:

Netherlands and cities near the sea suffer from many flooding problems at times when the sea level is high. In addition, as a result of climate change, we know that the Antarctic foothills are melting and adding water at sea level, causing residents of low-lying countries and cities near the sea to be concerned about possible flooding.

Flooding causes many economic and emotional problems, and can cause illness and drowning, which allows us to state that flooding is life-threatening. To avoid these problems, residents of these regions need to build protective barriers in places that do not have natural barriers such as slings and swamps. Protective barriers aim to reduce or prevent the advance of water to urban areas, thereby ensuring the safety of citizens.
