confirmed there was liquid flowing water on Mars on the 28th of September. The water was found running down slopes in the warmer months when the temperatures were above -10℉.

Clean water is extremely essential for a healthy living. It is life’s most important basic necessity while dirty water is one of the deadliest killers. UN has estimated that 10 people die every minute from contaminated water. The World Health Organization estimates that 80% of all sickness and disease in developing countries is due to unsafe water. As water pollution is one of the most widespread problems and it has deadly effects‚ I chose this topic. Water pollution is the contamination of water bodies
