Why should the "Great Northern Wilderness" return farmland to "famine"?

When I was a child, my hometown, Daba Mountain, was full of crops, but I could only solve the problem of food and clothing, and my life was still very difficult. After 2000, my hometown began to implement the policy of returning farmland to forests. Trees are planted in big mountainous areas, and they are no longer cultivated. The state subsidizes some food and money every year, but our life is better. At least we can eat flour and rice freely instead of corn. The Great Northern Wilderness began to reclaim large areas from 1948. After several generations of hard construction, the Great Northern Wilderness has become a great northern warehouse. Over-exploitation of the Great Northern Wilderness has also produced a series of environmental problems, leading to the rapid deterioration of the natural environment in the Great Northern Wilderness. In order to protect the environment, the Great Northern Wilderness began to return farmland to forests on a large scale to realize the harmony between man and nature.

The Great Northern Wilderness is located in Sanjiang Plain, Heilongjiang Plain and Nenjiang River Basin in the north of Heilongjiang Province, China. Rich in water resources, with rivers on the surface, considerable groundwater and abundant precipitation, it is extremely suitable for agricultural development. The Great Northern Wilderness lies in the frontier. There are overgrown weeds, swamps, snowstorms, herds of wild animals, sparsely populated, cold, remote, desolate and dangerous. So this area has never been developed in ancient China.

1948, China * * * opened the prelude for immigrants to develop this wasteland. In the 1960s, the state organized demobilized soldiers, peasants and educated youth to reclaim the Great Northern Wilderness on a large scale, and set up the Heilongjiang Production and Construction Corps to manage the development of the Great Northern Wilderness. Through the hard work of the people in the Great Northern Wilderness, Great Northern Wilderness has become a great northern warehouse, with 1 13 farms, more than 2,000 enterprises, 35.6 million mu of cultivated land and1.778 million people. It has the most advanced modern mechanized agricultural model and the highest commodity grain production base.

After the reform and opening-up, China's productivity has been further improved, and its agricultural efficiency has been greatly improved. The grain produced can not only be eaten by itself, but also be exported abroad. Modern industrial socialization has replaced agricultural society, and information society has replaced industrialized society. Therefore, the state pays more and more attention to environmental protection and vigorously implements the policy of returning farmland to forests. Green mountains and green waters are Jinshan Yinshan.

Due to the excessive reclamation of the Great Northern Wilderness, the wetland area has been reduced by 80%, and a large number of rare animals have lost their habitats. The original black land was gradually salinized and salinized, and the sandstorm in the Great Northern Wilderness increased obviously. There are 8.7 billion tons of surface water loss in the Great Northern Wilderness, and the wetland area has decreased from 34,000 square kilometers in the 1950s to 4,490 square kilometers at present. The continuous deterioration of the environment finally made the country decide to stop developing the Great Northern Wilderness to protect the ecological environment of the Sanjiang Plain. Of course, most of the high-quality cultivated land that has been built has not been returned to forests, and all other land developed in the later period has been returned to wet land, ensuring the harmonious coexistence between man and nature.
