A tree grows tall and deep, spreading both its branches above the ground and its roots underground, therefore it makes the ground fresher and softer for other plants to settle. The roots increase the soil drainage and aeration, some trees can even fix nitrogen and enrich the soil. The leaves and branches of the tree shadow the ground and reduce the soil evapotranspiration and thus reduce the need for irrigation. A tree is the home of various living beings such as insects, birds and plants.

A tree is also great for farmers. It can be a source of food and medicine for home, and a source of fodder for the livestock. The wood can also be burnt and used to cook or warm up the house. A tree is definitely a valuable companion, so why are farmers neglecting it?
