What are the advantages and disadvantages of public transportation?
The main advantage of using public transportation is that it's cheap and generally much better for the environment,because you are only using one vehicle instead of many.Especially if your buses run on clean air,you can reduce a lot of emissions.Another advantage of public transportation is that it reduces traffic jams.I think public transportation is less stressful because you don't have to worry about parking and all that kind of thing.The big disadvantage of public transportation is the wait.It's much more convenient to just jump in your car and take off.Also,you have to follow a route and you have no flexibility with public transportation.Sometimes it can be very uncomfortable,especially during rush hours.

the importance of

46 billion years ago.There is a blue planet in the vastness of the universe was born,she is so beautiful.That is our mother - the Earth.
46 million years later,though also young and vigorous but not because his youngest child - the human,so she was very sad.
In today's world,human beings are to the fast-fast to destroy our own homes.Because the forests are destroyed,air pollution,soil erosion,so that the earth every day,100 species extinction,according to this speed by 2010 the world would be as many as 100 million known species on Earth disappeared.What a terrible one set of data ah!By that time,Asian elephants and the tigers will never become relics of history.Environmental issues is not only a country or a region's problems,has now developed into a global problem.The growing problem of environmental pollution,waste gas,waste water or solid waste can be transferred from one country to another.Some environmental problems and even affect the survival and development of mankind.For example,the Amazon rain forest destruction,will have an impact on the global climate; elevated atmospheric CO2 concentration and the destruction of the ozone layer,but also a threat to all mankind.
Thus,if people do not attach importance to the environment around us,the Earth will be completely turned into another one like.Human ah!You should wake up,do not hurt our own "mother" Do not let the most pro-"person" as you are sad,you cry.
Good news is that environmental issues have been around the world attention.Countries around the world have set up nature reserves,eco-park,so that a variety of animals,plants also have their own "Paradise." States have also developed a corresponding environmental policy,governance polluting enterprises to prohibit emissions,waste water,waste residue.Returning farmland to forests and restore wetlands to protect ecological balance,reduce air pollution,but also the world's a clear water and blue sky.
People around the world are to contribute to the environment,in my hometown of Shizuishan certainly no exception.Shizuishan City in the east,there is a beautiful lake called Lake Xinghai,where the beautiful scenery,fine spring.In the one side stands a particularly peculiar,striking the mountain - China Mountain rocks.Where the stones of various shapes,is both varied and numerous.Who could have thought that there was once a kind of a place?In a few years ago,it was actually a beautiful lake is made to throw up the "stinking puddle," and that was actually a mountain ash mountain stones,like only the big black bear lying where it is.As long as a wind blows,where black becomes hazy,crowded in upon.Who are industrious and brave Shizuishan created a miracle,this former "stinking puddle" into a paradise on earth and turned into pink Liulv scene today.Pleasant landscapes,lakes and mountains Xiaguang splendor ......
Some people say:"When the last one left on earth tiger,finally a crocodile,the last one bears in vain,whine to find a spouse,people will see their end." As long as people around the world work together to protect the environment,do to man and nature live in harmony,that day may never come.
The Environmental Protection from me to start!
