Question

How many people in the world lack regular access to clean water today and how high might this number grow by 2025?

A) 1 billion, 2 billion
B) 2 billion, 3 billion
C) 3 billion, 4 billion
D) 4 billion, 5 billion

Answer 1

Over 1 billion people globally currently lack access to clean water, and by 2025, the number of people facing water stress could rise, with estimates suggesting up to 3 billion could be affected.

Step-by-step explanation:

Currently, there are over 1 billion people around the world who lack regular access to clean water, and this situation is projected to exacerbate in the coming years. Given the current trends in water usage and expected population growth, especially in developing nations, it's anticipated that by 2025, two-thirds of the global population could be living in countries experiencing moderate to high water stress. When we look at the options provided, considering the referenced data and predictions such as more than half of the world's population may face water shortage by 2025, the most accurate choice seems to be B) 2 billion, 3 billion.
