The Earth's Hydrosphere

      Hydrosphere is a layer of water on the earth's surface. It is often called "water sphere" for hydro means water, and sphere. It includes all the water including oceans, streams, rivers, lakes and other kinds of freshwater, groundwater, saltwater and water vapor.

     Water is the most abundant surface of the earth in which it makes our place special. The world’s oceans contain 97% of the water in the hydrosphere, most of which is salt water. Ice caps, like that found covering Antarctica, and glaciers that occupy high alpine locations, compose a little less than 2% of all water found on earth (Wikipedia).

     Hydrosphere is important to us because it affects everything that happens in our lives. Water is everywhere. And its purest form is H2O. One of the importance of hydrosphere is it is a part of living cells. This allows the cell to function normally. Without water, cell would not be able to carry out their normal functions and life could not exist. Another importance is, water provides habitat. The hydrosphere provides habitat for animals and plants like water lilies, corals and fishes.

This proves that hydrosphere provides habitat for the fishes.

     Hydrosphere also helps regulate the climate. It is important because it helps regulate the temperatures on earth so that they stay within a range that is acceptable for life's existence. Another importance is that it helps provide human needs. We use water in many ways. We use it in drinking, washing and in other domestic and industrial uses. 

     These are just a few of the very important uses and functions of the water. 

The Impacts of Science and Technology

     Science means a system of acquiring knowledge and technology means applied science. So, many things will be invented or innovated through science and technology. Science and technology has impacts on our lives, on us human beings. It has advantages and disadvantages.

   There are many advantages of science and technology that can help us men. The advancement of technology helps the lives of the people make easier and has decreased the manual work.

This shows that the computers (with internet connection) help us do our 

researches and also help us communicate with other people throughout the world.

     As seen in the picture above, computers are a big part of our lives especially that it increases the communication between families. Emails and IMs enhance the communications of people. Technology also increased our productivity in agriculture. It also help us cure our diseases through the machines invented by scientists. And as for transportation, we could have had a long period of time to travel from one place to another if cars or planes aren't invented. Access to technology improves education. Almost all of our questions will be answered through the internet.

     

     On the other hand, technology is also misused that could lead up to environmental problems and health issues. This will also require so much of our skills and capabilities, so, this could lead up to increase of unemployment. And unemployment could lead to poverty. It also includes some disastrous disadvantages which can be a great harm for us. For some instances, we get addicted to some particular things and the more we get addicted, the more it can harm to us. 

The increase in transportation technology has brought to stressful

traffic in some areas.

      

     Science and technology also result to laziness, new diseases, and loss of personality. Many new online games as new forms of entertainment will affect the personality of oneself and will cause poor academic performances.

     

      Science makes our life comfortable. In fact, we need it in our daily living. Without science, today would be impossible although there are some disadvantages. We should always keep in mind that inventions, discoveries or innovations must not be abused to lessen the disadvantages of technology because science and technology is a big help to us.
