Final answer:
Increased global demand for freshwater is directly correlated with population growth, improved standard of living, increased production of goods and energy, uneven distribution of precipitation, lack of access to safe water and sanitation, water stress, and issues of sustainability.
Step-by-step explanation:
The increased global demand for freshwater is directly correlated with several factors, including population growth, improved standard of living, and increased production of goods and energy. As the global population tripled during the 20th century, water demand grew by a factor of six, surpassing the rate of population growth. This is due to the higher standard of living without an offset by water conservation. Additionally, the increased production of goods and energy requires a significant increase in water demand.
Furthermore, uneven distribution of precipitation around the globe plays a crucial role in freshwater availability. Areas near the equator receive more precipitation, while areas near the north and south latitudes, where deserts are located, receive less precipitation. This uneven distribution of precipitation affects the availability of freshwater.
Other factors contributing to increased global demand for freshwater include a lack of access to safe water and safe sanitation, water stress caused by current trends in water use, and issues of sustainability and access to resources, particularly in urban areas.
