Refertilization Land
Forest destruction is the main cause of the expansion of desert / rock soil.
This is the fault of humans who are always greedy. To feed the growing number of people on this earth, forests are cut down to be used as agricultural land and pastures.
Many of them do not pay attention to its preservation. Gradually this land became infertile and eventually turned into a desert.
After becoming a new desert thought tap to restore its fertility. Luckily there are still some researchers who care and immediately develop a program to restore barren land to become fertile again.
The process of soil fertilization is very dependent on living things that are in the soil. Animals that are very useful for the process of soil enrichment are worms, microbes, and other small animals. They form holes and regulate the exchange of water and air in the ground.
The animals have turned the remains of leaves, twigs, stems, roots, and the remains of animals that have rotted into humus. They breathe and look for food here and there in the ground so that the soil becomes loose
Finally, with simultaneous efforts and helped by increasing public awareness, this program was able to show its success.
The barren land begins to turn green and can be planted again.
people finally realize their mistakes and promise not to repeat the same mistakes.
