Answer:
In biology, a pathogen (Greek: πάθος pathos "suffering", "passion" and -γενής -genēs "producer of") in the oldest and broadest sense, is anything that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ.
The term pathogen came into use in the 1880s.[1][2] Typically, the term is used to describe an infectious microorganism or agent, such as a virus, bacterium, protozoan, prion, viroid, or fungus.[3][4][5] Small animals, such as certain kinds of worms and insect larvae, can also produce disease. However, these animals are usually, in common parlance, referred to as parasites rather than pathogens. The scientific study of microscopic organisms, including microscopic pathogenic organisms, is called microbiology, while the study of disease that may include these pathogens is called pathology. Parasitology, meanwhile, is the scientific study of parasites and the organisms that host them.
There are several pathways through which pathogens can invade a host. The principal pathways have different episodic time frames, but soil has the longest or most persistent potential for harboring a pathogen. Diseases in humans that are caused by infectious agents are known as pathogenic diseases, though not all diseases are caused by pathogens. Some diseases, such as Huntington's disease, are caused by inheritance of abnormal genes

The combustion of fossil fuels like coal, petroleum, and other factory combustibles is a major cause of pollution.
Breathing polluted air puts you at a higher risk of asthma and other respiratory diseases. High levels of particle pollution have been associated with higher incidents of heart problems. The burning of fossil fuels and the release of carbon dioxide in the atmosphere is causing the Earth to become warmer.
