As making much importance of the present benefit and convenience ,about the fact that ecology is in
danger, many people have ignored because they think as there is no problem. But, this attitude has to be
charged as soon as possible.
To do like that. people have to realize the seriousity of the situation. Especially, chemists need to be
careful about producting quantity of chemical materials that is not insecticide but the destruction of life.
There are many problem. For example Soon after scattering insecticide, any serious problem doesn’t
generate, but the poisonous substance is latent in the interior of its body. And a few month or years later,
it causes any problem. Not only this, If a mother eat food that is contained chemical material, it affects
the fetus. Also, If a bird eat crop or seed scattered agricultural insecticide, it is killed. In a word this
makes the repeat of vicious circle.
And a mass production of a agriculture and single crop’s cultivation also destruct variety of the
nature. Because it disturbs internal check and balance the nature does act. Losing many kinds of life is
very anxious matter related to environment. Lots of environmental farmer have collected or used the
precious seed succeed for decades. All over the world many people’ve discussed about the agricultural
methods environmentally friendly and security for preservation of life’s variety. It is important to
preserve a variety of life. Because the variety only save us.
In conclusion, we need to have basic knowledge about the life’s trait correlation between life and
environment to weaken explosive power and new attack of damages by blight and harmful insects, to
keep the balance of the nature. It is also need ecological access that make much of interaction between
life and environment. This pursues coexistence of people and the nature.
