What percentage of the human population of the world does not have reliable access to clean water? a 70% b 80% C 20% d 30%

The correct answer is a) 70%.According to the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF), approximately 70% of the human population does not have reliable access to clean water. This means that out of every 10 people in the world, 7 do not have access to safe and clean drinking water.Access to clean water is a fundamental human right, and it is essential for maintaining good health, preventing the spread of diseases, and supporting economic development. However, many people around the world still lack access to this basic necessity, particularly in developing countries and rural areas.Efforts are being made to improve access to clean water through initiatives such as the construction of water treatment facilities, the installation of community-based water systems, and the promotion of water conservation practices. However, more needs to be done to ensure that everyone has access to safe and reliable water sources.
