**Abstract**

Microplastics are defined as a tiny plastic particle with length less than 5 mm that result from commercial product development and the breakdown of larger plastics can be considered as harmful to our environment. The surfaces of plastic tiny fragments can be carrying disease-causing organisms and acts as a vector for diseases. The microplastics can found in water and soil carrying different types of contaminants. The small particles of microplastics serve as carriers for bacteria and persistent organic pollutants, which are considered as biodegradable material that remains active for years. The main definition of microplastics and their source as well as the effect of microplastic waste on the human health with the main solution that helps to eliminate this kind of waste will be explained in this chapter. It was found that the human person eats high quantity of microplastic particles every year through breath air, drinking water, and eating plant crops and animals. On the other hand, sea fish can contain microplastic parts due to drinking and eating sea water with microplastics. Therefore, it is very important to reduce throwing of plastic waste on the ocean and landfill to avoid the effect of microplastic on the human health.
