Learning From Nature

What is nature? Based on Wikipedia Nature is the phenomena of physical world collectively including plants,animals,the landscape and other features and products of the earth,as opposed to humans or human creations.What we have done to nature? We’ve done exploitation,we didn’t take care of earth, we cause a lot of pollution, we destroy the nature,and others.

What is included in nature? that belongs to the nature among others are:

1.       Oxygen

What is oxygen?based on Wikipedia Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms oxides with most elements as well as other compounds.Why we need oxygen?we need oxygen because without oxygen we will not live,why? Because we are earth creatures that need oxygen.

2.       Natural Gas

What is Naturel gas?based on Wikipedia Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.^[2] It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas.^[3]Natural gas is a fossil fuel used as a source of energy for heating, cooking, and electricity generation. It is also used as fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals. It is a non-renewable resource.^[3]Natural gas is found in deep underground rock formations or associated with other hydrocarbon reservoirs in coal beds and as methane clathrates. Petroleum is another resource and fossil fuel found in close proximity to and with natural gas. Most natural gas was created over time by two mechanisms: biogenic and thermogenic. Biogenic gas is created by methanogenic organisms in marshes, bogs, landfills, and shallow sediments. Deeper in the earth, at greater temperature and pressure, thermogenic gas is created from buried organic material.Why we need Natural gas? because  Natural gas is the fuel our daily. for example, fuel for cars, motorcycles,and some many others.

3.       Water

What is water?based on Wikipedia  Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is H₂O, meaning that its molecule contains one oxygen and two hydrogen atoms, that are connected by covalent bonds. Water strictly refers to the liquid state of that substance, that prevails at standard ambient temperature and pressure; but it often refers also to its solid state (ice) or its gaseous state (steam or water vapor). It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity. Why we need water? Because without water we will become dehydrated because our body is 60-70% water. without water in our bodies, we are just inanimate objects that consisting of skin and bones.

What disaster that occurs in nature?

1.Earthquakes

2.Volcanoes

3.Flood

What we can do?

1.Save electrivity

2.Use water wisely

3.Grow a plants.
