At the beginning of the twentieth century, the first synthetic chemical compound was created. Due to the enormous use of plastics in our daily life and their inappropriate discarding is a global issue. Nowadays, we can see the plastic used in everyday work such as from the packaging of our food to the shopping bags and from household items to the lining of our water pipes and helmet of our bikes and even vehicles lightening is possible due to plastic. The production of plastic compounds reached 348 million tons in 2017 which will be reached to 33 billion tons by 2050. We used plastic for above mention purposes because of plastic property to be elastic or it does not degrade easily, which provide long-lasting character to the plastic. Plastic revolutionized the world as it made space travel possible and most life save equipment are made from plastic. Despite these benefits of plastic, it becomes major environmental pollution. Due to it cannot degrade easily, a single plastic bottle can stay in the environment for 500 years. In the modern era, it is considered as an emerging contaminant.

Humans are adding a large amount of waste in the water bodies and soil environment which is mostly Plastic. Therefore, micro plastics are present in all the compartments, and they may enter through different sources including primary sources (industrial and domestic products) or from secondary sources, due to the breakdown of larger plastic particles that are present in the environment. Micro plastics are generally formed by fragmentation of the larger plastic debris and have a dimension of less than 5mm. This is carried out through a variety of mechanical, chemical, and biological phenomena that convert it into small size plastic particles. There are different news and research work done on the plastic effects in the world that shows plastic not only a dangerous pollutant for the animals but now it also becomes hazardous for human as well. The recent report of WHO (World Health Organization) confirms the presence of tiny particles of plastic in the drinking water reservoirs. These tiny plastic particles that are less than 5mm in length are referred to as micro-plastic. However, according to the report, it is too early to say that it can cause an adverse effect on human health because there are research data gaps which need to be considered. However, there is clear evidence that human is ingesting plastic in the form of microplastic. As it is a long-lasting substance that can live in the environment for hundreds of years, it can also bioaccumulate in the human body. It may be harmful to human health. It is only a matter of time; we will find about its hazardous effects. Moreover, Micro plastics pollution in aquatic ecosystems is caused by a variety of terrestrial and marine-based processes, including household and industrial drainage, agricultural runoff, and wastewater treatment plant effluent. Micro plastics have been found in human food and air samples, and exposure to Micro plastic through consumption or inhalation might have negative health consequences. It may cause different disease including neurotoxicity, diabetes, and cancer.
