Water where would we be without it

Where would we be without water? There is only one word to answer this question. DEAD! There would be absolutely no life on earth without it. The earth would be a giant, dry rock with no life upon it. No plants, No animals, No humans. It is impossible to live with out it, and it is the most important thing we have on the earth.

Plants are another extremely important part to life on earth. However, there would be no plants without water. Plants need water for many reasons. The main reason, and most obvious reason, is because they need water to stay hydrated and to stay alive. Pants need to drink just like humans do. If they didn't, they would just wither up and die off. Another reason plants need water is for photosynthesis. Photosynthesis is the process by which plants use their energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The plants get their water from the soil, which the roots suck up into the plant and use for a number of different reasons. The water that is brought up through the roots is then distributed to all the veins in every leaf to keep the plant hydrated, and to supply the whole plant with all the nutrients it needs. The water that is brought through the veins is also needed for the cells in the plant to carry on
photosynthesis, and is required for cell expansion and growth. Another important thing that water does for plants, is keep it cool on warm days. The water that is evaporated from the plant, by the sun, acts as a sweat for the plant, which keeps it from getting too hot. It is the same process that humans go through. The most important reason plants need water, is to stay alive and produce oxygen for humans and other animals. Plants are the only reason there is humans. If there were no plats, there would be no humans or animals because there would be no oxygen for breathing.

The most devastating thing that would happen if there were no water would be the non-existence of humans. Without water all humans on earth would be dead within one month. A human body is comprised of 80% water. We need to have at least 70-80 ounces of water every day to keep our body properly hydrated, so within one day, our body would already be suffering from lack of water. Consistent failure to drink enough water can lead to Chronic Cellular Dehydration. This is the condition where the body's cell are never quite hydrated enough to leave them in a weaken state, vulnerable to attack from disease. It weakens the body's overall immune system and leads to chemical, nutritional, and pH imbalances that can cause a host of diseases. It is needed for almost every bodily function to properly take place. H2o is essential for proper digestion, nutrient absorption, and chemical reactions. Without water in the body, we wouldn't even be able to eat. We need saliva to digest our food, and without water saliva cannot be produced. Another vital part water plays on the body is that it is needed for proper circulation. It makes blood flow easier through the veins and arteries. When we eat, we have to get rid of our waste some how. Water helps remove toxins and waste from the body, particularly from the digestive tract. Humans also need to stay at a certain temperature to stay healthy. Water is also what regulates our body temperature. When it is hot out side, our body releases water from inside and it comes through the pores in our skin, cooling us down. This is the process known as sweating. Without this, we would over heat and most likely die a slow and hot death. Just like plants are important for humans and animals to exist, humans and animals are important for plants to exist. We are what make the carbon dioxide that they breathe, and without us there would be no plants at all.

70% of the earth is water, and for that all to be gone would be devastating. That would result in no marine life on earth at all. No fish, no water mammals, no crabs, no shells, no fun and exciting boat rides, no water power or energy, no scuba diving, no aqua experiments, and hundreds of other things would be lost as well. Fish and other animals that live in the ocean are main sources of food for humans and other animals. They have been since the beginning of life on earth. Not only are marine animals used for eating, but they are also used for entertainment, show, and as pets. Amusement parks, water parks, and aquariums around the world use marine life as one of their main attractions. Marine life is also a major moneymaker, but without water it would all be gone, and a lot of jobs would be lost. People also use water as a place to relax and enjoy a day out on the boat. A very large percentage of the world owns a boat, but they would be completely useless if there were no oceans, lakes, or rivers to take them out on. The world would be a totally different and boring place without water in existence. Not to mention that there would be no life on earth, so we wouldn't be able to not enjoy it anyways.

These are some of the many reasons why we need water in our everyday life in order to live. It is the most crucial thing that we need as humans. Plants also need it just as much as humans do, if not more. We often take water for granted and we don't think about where we would be without it. This helps me to appreciate it more and to take it for granted. I am now thankful for all the H2o I have.
