Influence of farming civilization on natural environment

1. The beneficial effects of farming civilization on the natural environment;

Some animals and plants have been protected: the emergence of farming civilization has changed the way of life of human beings from gathering and hunting to agricultural production, thus reducing the killing and destruction of wild animals and plants and protecting some endangered species.

Improvement of land use efficiency: the emergence of farming civilization has enabled human beings to improve land use efficiency through irrigation and fertilization, thus reducing the occupation and waste of cultivated land and protecting some natural ecosystems.

Increased land greening and improved climate: agricultural production needs a large number of plants, so the emergence of farming civilization has also promoted land greening, improved climate and improved the ecological environment in some areas.

2. The adverse effects of farming civilization on the natural environment:

Some natural ecosystems have been destroyed: in order to increase the cultivated land area, people often carry out large-scale reclamation and transformation, resulting in the destruction of natural ecosystems such as forests and grasslands, and the problems of soil erosion and desertification are becoming increasingly serious.

Destruction of vegetation: In order to expand the cultivated land area and increase crop yield, people often cut down and burn natural vegetation such as forests and grasslands, which not only leads to the decrease of biodiversity, but also aggravates the problems of land degradation and water resource depletion.

Excessive use of water resources: agriculture needs a lot of water resources. In order to ensure the growth of crops, people often use irrigation to improve the utilization rate of water resources, but it also leads to environmental problems such as the decline of groundwater level, the drying up of rivers and the deterioration of water quality.

Aggravated pollution: With the continuous expansion of agricultural production scale, the problem of agricultural pollution has become increasingly prominent, such as the pollution of pesticides, fertilizers and livestock manure to the environment, which has brought serious impact on the natural environment.
