Toxic waste can harm the environment and public health if not properly disposed of. It includes chemical waste from manufacturing and mining activities that can contaminate soil and waterways. Improper disposal increases risk of water pollution and disease. Proper disposal methods include special landfill liners to prevent chemicals from leaking and precautions to protect the ecosystem. Reducing and recycling waste, strengthening disposal laws, and finding ways to break down waste compounds can help address the toxic footprint waste has already left.
