Introduction of an undesired component in the natural ecosystem is called as pollution. Wastes like plastic, chemicals, industrial effluents etc., causes damage to the natural micro flora of soil. Due to this soil pollution is lead.

Presence of unwanted contaminant in soil is called soil contamination. The deposition of pesticides on fruits and vegetables lead to its accumulation in fatty tissues of the host. This phenomenon is called bio accumulation.

The toxicity of pesticides is affecting the human health due to excessive accumulation of the pesticides in the food. Pesticides mixed with water are non-biodegrable in nature, due to which various water borne diseases are occurring in humans. 

Explanation: Overgrazing, over cropping and or deforestation can lead to desertification the spread of desert like lands due to these human activities accelerating natural erosion of soil.

Presence of unwanted contaminant in soil is called soil contamination. Non-biodegradable chemical pesticides are the largest source of soil pollutant.  organo-chlorides are group of insecticides based on chlorinated hydrocarbons (organochlorines).

Xenobiotics are the unwanted chemicals or particles of compounds which are found in the regions where generally they are not present. These are the foreign particles like the herbicides, pesticides, agrochemicals like fertilizers, etc. These are the chemicals which might interact with the bacteria and other microorganisms in the soil. This might affect the absorption of nutrients by the plants.

The Sunderbans is a natural region in Bengal. It is the largest single block of tidal halophytic mangrove forest in the world. A mangrove is a tree, shrub, palm or ground fern, generally exceeding one half metre in height, that normally grows above mean sea level in the intertidal zone of marine coastal environments and estuarine margins. A mangrove is also the tidal habitat comprising such trees and shrubs.

The Sundarbans contain the world's largest mangrove forests and one of the most biologically productive of all natural ecosystems. Located at the mouth of the Ganges and Brahmaputra Rivers between India and Bangladesh. The mangrove habitat supports the single largest population of tigers in the world.
