Healthy and industrial farm system
There is a phenomenal difference between healthy farm systems
compared to an industrial farm. A healthy farm system is
sustainable. This system includes having healthy plant roots
that store water and nutrients and the support given to the plant
from the base is stable. The soil is kept in balance. To replace nutrients crops are
rotated. Animals that graze the land, their waste are used as fertilizers. On the other hand industrial
farming is unsustainable system. The land is used continuously using machines. Unlike healthy
farming system which rotates the crops; industrial farming doesn't which replenishes the soil. Also, this system uses chemical
fertilizers and manure to feed the soil.
Causes of animal manure
Animal waste has an enormous quantity; which is too much for the land to absorb. Not only is it difficult to hold, it also
releases harmful gases in the air.
Air & water pollution
The factory farms pollute the air in many ways. This includes giving off greenhouse
gases and some toxic chemicals; which contribute to Global Warming. Toxic
chemicals emitted by the factories can harm the health of nearby neighbours.
Water pollution is one of the major issues in industrial farm system. Water is the
main source of life for human beings. But, this system is making it unsafe for us to
drink. Usage of water in the factories is tremendous. This means we will run out of
this source one day! The leaks and runoffs from the factory can kill aquatic life.
Problems of feeding crops
Croplands are forced to produce an enormous amount of grain.
The natural balance between the soil and crop yields is lost due to erosion of soil
and loss of fertility.

Here's a taster:

The after effects of chemical fertilizers are long term depletion of organic matter; soil compaction; and degradation of soil
When the land is not in use the soil is bare and is exposed to erosion.
In a hilly terrain; when ploughing up and down hills is not done it leaves furrows which carries the wet soil straight
Soil erosion causes fertile farmland to lose nutrients and water retention ability.…read more
