Now, the problem that a wild animal gets down to a town to hunt for food and breaks a thing is increasing. In Japan, it has still ended with the level of a monkey, a wild boar, and a bear. There is also a phenomenon for some countries where elephants pounced in large crowd and it ruined the town.
The cause of these problems is that the normal function of a forest is lost and there is nothing to be eaten.
We human are made to pay the compensation by carrying out random development and having planted only the needle-leaf trees which do not become the food for a wild animal.
The problem is not only it.
By losing the function of a forest, the filter which purifies water does not function and it causes a mudslide.
What should we do in order to recover the lost forest?
This is the very situation for a lot of lactobacilli and organic wastes.
By scattering those in large quantities, a forest regains the function and the wild animal also comes to return gradually.
