Poor soil management-with poor soil management, swamps probably would not grow as well as it would today. Poor soil management can result in three problems: erosion, nutrient depletion, and desertification.
Deforestation:with deforestation swamps would not be here, deforestation affects soil, the flow of water, biodiversity, and Earth's climate.
Urbanization: it is when large areas of land are developed as more and more people move to cities and suburbs, because of Urbanization it impacts Earth through the loss of land for other uses and through pollution of air and water.
Air pollution: pollution of the atmosphere. Today, a large source of emissions resulting in air pollution outdoors comes from motor vehicles such as cars and trucks.
Water pollution:Most water pollution is the result of human activities. Wastes produced by agriculture, households, industry, mining, and other human activities. Because of this freshwater swamps would die and this would go in our drinking water.
