Explanation:
Introduction
Water is an essential part of our ecological system. It is one of the main substances that make our planet fit for living. Water is essential for the growth and development of plants and animals. We use water directly as well as indirectly for many of our needs.
Water – An Essential Part of the Human Body
Research shows that up to 60% of the human body is made of water. Our lungs are around 83% water, our muscles and kidneys are 79% water, our brain and heart are 73% water, our skin contains 64% water and our bones have 31% water. Water helps in several functions of the body including blood circulation, digestion, regulating body temperature, protecting tissues and joints and excreting waste via perspiration, defecation and urination.Our body continually uses water to perform these functions. So, we need to provide a continuous supply of water to our body to help it function well. It is important to replenish the lost water timely.
Water – Vital for Plant Growth
Plants prepare their food by way of photosynthesis. Water forms an essential part of this process. As we water the plants, it enters their stem and moves up to their leaves. It draws nutrients from the soil and carries them to the leaves. Photosynthesis takes place in the leaves. The water present in the leaves evaporates and is exchanged for carbon dioxide.
Without proper supply of water, the plants do not get enough nutrients and photosynthesis cannot take place. As a result, the plants begin to droop and fall. Different kinds of plants require different amount of water at different times. While some plants need to be watered twice a day others require water once a week while there are yet others that can go weeks without water especially during cold and moist season.
Water – Habitat for Marine Creatures
Water serves as home for the marine creatures. Wide variety of fishes, turtles, frogs, crabs and other marine creatures live in seas, oceans and rivers. These water bodies are their habitat. Most marine creatures live solely in water and cannot survive on land. They add to the biodiversity and are an essential part of the eco system.
The increase in the level of water pollution is causing a threat to these beautiful and innocent creatures. Many species of the beautiful marine creatures have either gone extinct or are endangered. Water pollution is caused due to various human activities. It needs to be controlled in order to provide a safe and healthy habitat for the marine creatures.
Conclusion
Water is vital to the survival of living beings. Even as water recycles naturally, the amount of fresh water on Earth is depleting fast. This is all because of the negligence of human beings. We use water for several purposes throughout the day. But we aren’t using it efficiently. We waste it more than we use it. This is the reason why water is decreasing at a rapid speed. It is high time we must use water wisely and limit the activities that pollute it.
