It is hazardous if found in the body of aquatic organisms and can be transferred through various types of organisms until it ends up in humans through the food web. This transfer of microplastics in the food web becomes an issue which threatens human health. b) Emissions from burning fossil fuels like coal, natural gas, and oil to generate electricity and heat homes and buildings. c) While renewable energy sources like solar, wind, and hydroelectric power have a lower carbon footprint, the production and installation processes can still contribute to overall emissions. d) Emissions from the production of goods and materials, including the extraction of raw materials, processing, and transportation.
