Detailed explanation-1: -Perhaps the single greatest impact of European colonization on the North American environment was the introduction of disease. Microbes to which native inhabitants had no immunity caused sickness and death everywhere Europeans settled.
Detailed explanation-2: -There were many environmental effects of European expansion, including deforestation, land degradation, the introduction of foreign animal and plant species, and the spread of European diseases.
Detailed explanation-3: -When the Europeans arrived, carrying germs which thrived in dense, semi-urban populations, the indigenous people of the Americas were effectively doomed. They had never experienced smallpox, measles or flu before, and the viruses tore through the continent, killing an estimated 90% of Native Americans.
