All living things on earth need WATER to survival. Only oxygen is more essential than water in sustaining the life of all living organisms. Human beings can live for several weeks without food, but only a few days without water. The quality of your tissues, their performance, and their resistance to disease and injury are linked to the quality and quantity of water you drink. Experts agree that in order to maintain optimum health one needs to drink 8-10 glasses of water per day. The daily cleansing of wastes from each cell, the flushing of the alimentary canal and the purifying of the blood are all dependent on our water consumption.

For most of the organisms on earth it is very important? Is it important for all organisms on earth? I'm not sure, there may be some that do not need water to sustain life but possibly some other liquid, although those are probably all micro-organisms. Most organisms would die quicker if they were deprived of oxygen, but does that necessarily mean oxygen is more important? Some bacteria are anaerobic an don't need oxygen. Plants take in CO2, but does that mean they truly need oxygen (O2)?

At least here on earth, I'd say the most essential life sustaining element is carbon, because pretty much every life form on earth is made out of carbon and we have yet to find life forms outside of earth.

All the life on this Earth needs water for the survival of life.Earth is a truly unique in its abundance of water. Water is necessary to sustaining life on Earth, and helps tie together the Earth's lands, oceans, and atmosphere into an integrated system. Precipitation, evaporation, freezing and melting and condensation are all part of the hydrological cycle - a never-ending global process of water circulation from clouds to land, to the ocean, and back to the clouds. This cycling of water is intimately linked with energy exchanges among the atmosphere, ocean, and land that determine the Earth's climate and cause much of natural climate variability. The impacts of climate change and variability on the quality of human life occur primarily through changes in the water cycle. As stated in the National Research Council's report on Research Pathways for the Next Decade (NRC, 1999): "Water is at the heart of both the causes and effects of climate change."

All life needs water. It keeps life hydrated it transports nutrients, it is the universal solvent, it provides habitats for most of the planet's animals.
