A long long time ago, the earth was born about 4.6 billion years ago. Since then, today there is the earth as one of planets in the vast cosmos with numerous changes taken place through the very long history .
　A several million even several tens million kinds of living things including human being have been living in this little star of the earth for many many years.
　Before the birth of human being, many living things had been created and still living today, while there have been living things who have been already exterminated.

　WHOM IS THE EARTH FOR ?
　
　It is very obvious that the earth does not exist only for the human being.
　Can human being live alone ? Human being has been living so many years with great helps from and at the sacrifices of many other kinds of living things.
　We human being have no alternative other than living together with other kinds of living things with helps from them as before.
　In order for many kinds of living things to live together in this small star, there hase been an excellent balance between each living things and efficient wisdom which have been developed over so many years in the past .
　Each living things have own sanctuary where have been recognized as the territory untouchable by other. It seems to be worthy of the consideration that stepping into other sanctuary carelessly might result in a cause of AIDS and SARS which are the critical diseases of the human being have beeen recently infected with.

　Human being have established the civilization in many regions in the world, obtaining heat and light,using fire.
　However, burning so many trees for securing agricultural field and fuels have lost the huge space of forest and also deteriorated the green land to sand.
　Reportedly, during the year of 1991 to 1997, around 28 times land as much as total Japanese land space had become sand in the world.

　In the latter part of the 20th century, the MATERIALISM has reached the peak with the mass production,the mass consumption and the mass emission.
　In order to support and practice the materialism,human being have been consuming coal,petroleum,natural gas of the natural resources so much as if they are limitless and inexaustible resources. As the result, the environment of the inreplaceable earth has been deteriorated so crucially and the global warming has been taken place across the board.
