Toxic waste is any unwanted material in all forms that can cause harm. Mostly generated by industry, consumer products like televisions, computers, and phones contain toxic chemicals that can pollute the air and contaminate soil and water. Disposing of such waste is a major public health issue. Increased rates of cancer in humans and animals are linked to exposure to toxic chemicals. Toxic waste disposal is often seen as an environmental justice problem, as toxic waste is disproportionately dumped in or near marginalized communities.
