Environment plays an eminent role in depicting the physical as well as mental well-being of any creature either human or plant. Hence, a sound environmental condition is an absolute necessity of life to be healthy, both, physically as well as intellectually. But unfortunately, in the past few years, as the number of people progressed the consumption of food as well as fiber and other useful products has also increased. But very few policies are made for proper disposal and decontamination of waste products. This casualty has disturbed the nature to an extent that most of the areas of Pakistan are not able to adore the world of nature and its beauty.
            One of the major threats of environmental crisis is the ongoing pollution of water on daily basis. With the development of factories and industries on a large scale, their usage has also increased tremendously. As a result, their wastage has also increased to an extent that it is damaging the human health severely. In fact, it not only damages the human health but it also create some other disasters like it can highly damage the crops. The crops grown in the areas around the rivers and canals, substitute river water which is highly contaminated by industrial and domestic effluents. In case of domestic effluents, boron is one of the major toxic elements found hazardous to agricultural crops. Boron usually comes from certain bleaching agents used at home. It can cause damage to the crops that are sensitive to boron up to a certain limit e.g. sunflower, sesame, potato, onion, wheat, garlic and barley are sensitive only at the concentration of 0.5-1.0mg/L.

Conclusion:
            Similarly, in case of industrial waste, it also bear injurious effects to the crops. E.g. if any beverage industry is present near or around any agriculture field or it disposes off its wastes into the river or canals, which ultimately goes into the agriculture fields poses a high risk of damage as it contains alcohol in it. Moreover, Brewery effluents are high in carbohydrates nitrogen and the cleaning and washing reagents have been proved water pollutants. The introduction of waste water, high in organic matter and essential nutrients bring about changes in the microflora. Similarly, some other industries release other chemicals that are also harmful to the crops and ultimately the human health e.g. metal finishing industries are the major cause of oil and grease in water bodies.
The expulsion of industrial as well as domestic effluents into receiving water bodies consistently result in high concentrations of pollutant in the water and residue. These pollutants have shown to be highly toxic to different organisms. The effluents also have significant undesirable effects on the water quality of the receiving water bodies. Hence, they are rendered not good for human use. Therefore it is recommended that the careless discarding of industrial and domestic wastes without pretreatment should be discouraged. Obligation of direct charges on these effluents by the amendable agency, as well as continuous monitoring and scrutiny is vital in order to ensure the protection of water resources from further filth.
