Bioindicator emerged as a potential environmental marker

In the era of modern science and new technology, mankind is adopting new and novel approaches to deal with the problems. The high population density and urbanization has changed our environment to a polluted one. Its not easy to deal with this problem with complex and costly equipment. Bioindicators are playing a major role in reducing the pollution and to check it timely without any environmental hazard. Bioindicators are the living organism which facilitate in reduction of the environmental pollution. They directly or indirectly determine the amount of pollutants and contaminants present in our ecosystem. They rapidly react to their surrounding environment and give us early warning. These can be used for indexing the health of the ecosystem as well as balancing the ecosystem without any disturbance in food chain. Biomonitoring is one of the promising and cost-effective methods as compared to other techniques. More researches are highly needed to explore the hidden characteristics and many more new species which will help us to build a better and safe environment.

• Environmental pollution can be checked by using the potential bioindicators which are may be plant, animal or microorganisms.

• Being sensitive and specific, these bioindicators react against the slight change of the surrounding environment by increasing or decreasing the population density.

• Bioindicators not only restricted as environmental marker, but also widely diversified to help in search of specific species population, natural resources and extinct phylogenetic trend line.
