Inappropriately managed waste can attract rodents and insects, which can harbor gastrointestinal parasites, yellow fever, worms, various diseases, and other conditions for humans, and exposure to hazardous wastes, particularly when they are burned, can cause various other diseases including cancers. Toxic waste materials can contaminate surface water, groundwater, soil, and air, which causes more problems for humans, other species, and ecosystems. A form of waste disposal involving combustion creates a significant amount of greenhouse gases. When the burned waste contains metals, it can create toxic gases. On the other hand, when the waste contains plastics, the gases produce contain CO As global warming and CO emissions increase, soil begins to become a larger carbon sink and will become increasingly valuable for plant life.
