For all species, water is an essential requirement for life. Everyday, we need to drink water to maintain basic metabolism and perform physical activities. By keeping our water supplies clean, we can keep our environment clean. Furthermore, unlike Mars, water helps keeps our planet's temperature stable. However, due to pollution from many human activities, our natural resources are threatened--including clean water. Because industry releases polluted water into our rivers and oceans, animal and plant life accumulate toxic heavy metal in their systems. Moreover, animals closer to the top of the food chain concentrate more harmful ingredients in their bodies, especially humans. (This is called biomagnification.) Polluted water can makes us sick, weaken our immune system, and even cause cancer. Other species of animals also can not escape these dangers. Numerous turtles regularly die due to ingesting large quantities of plastic. Subsequently, larger marine life are also dying of starvation due to the decreased amount of smaller marine life--their natural prey. Unfortunately, not only are the variety of animals decreasing. but due to contaminated water, we are also losing beautiful beaches and fresh water. What should we do to keep the Earth's water clean? There are many ways: We can decrease our use of plastic products, refuse to buy products from negligent or polluting companies, and be proactive, informed consumers and citizens. We want a clean beach for everyone!
