nonrenewable. Renewable energy comes from resources that are continually renewed by the earth without human help such as wind‚ rain‚ sunlight‚ and geothermal heat. Nonrenewable energy comes from resources that exist in limited amounts such as coal‚ oil and natural gas‚ and nuclear energy. The world mainly functions on nonrenewable energy sources because it is cheaper than trying to use renewable energy. Renewable energy sources can be cheap but only after steep initial costs for startup. There are

Water conservation importance. Water is very important content. With out water there is no life in earth. We use water in so many ways in our daily life. Water is a substance which covers ¾ part of the world. It means water is occupying more portion compared to land. But this water is becoming more polluted because of the environmental changes. So it is necessary to conserve the water. It is every one duty to protect the water because everyone uses this water and we the people are making water polluted

to the importance of nature conservation. Thankfully‚ owing to the far-sighted pioneers (有遠見的先驅者) who headed the National Parks movement‚ there are now a number of reserves throughout the world where nature is allowed to reign supreme(最高)‚ and wild life is preserved(被保留)to be enjoyed by all. But over large tracts of the world’s surface the delicate balance(微妙的平衡) between man and nature is still being destroyed by industrialization‚ over-population and the resulting pollution.

Soils Conservation: Easier - Soil is the loose top layer of our planet’s crust. It is dirt or earth in which plant life can grow. Harder - Soil covers a major portion of the earth’s land surface. It is an important natural resource that either directly or indirectly supports most of the planet’s life. Life here depends upon soil for food. Plants are rooted in soil and obtain needed nutrients there. Animals get their nutrients from plants or from other animals that eat plants. Many animals make

Conservation of Energy In explaining the laws of conservation of energy‚ energy cannot be destroyed or made. Although‚ energy can be transformed or transferred from one form to another‚ for example: The total amount of energy in any system never changes but stays constant over time. Second example: Coal is burned‚ and then used as thermal energy for heat‚ next the steam is used for mechanical energy. Energy is never destroyed but changed to forms like thermal energy‚ gravitational energy‚ electromagnetic
