Which of the following is a consequence of improper hazardous waste disposal?

Improper hazardous waste disposal can lead to soil and water contamination, which is a serious environmental and public health concern. When hazardous waste is not handled correctly, harmful substances can leach into the ground and water sources, creating toxic environments for both ecosystems and communities. Contaminated soil can adversely affect agriculture, harm wildlife, and limit land use, while tainted water supplies can pose severe risks to human health, leading to illnesses and long-term health complications.

In contrast, the other options suggest positive outcomes or scenarios that are not typically associated with improper disposal of hazardous waste. Increased resource recovery and enhanced community development are generally linked to proper waste management practices, while protection of human health is undermined by hazardous waste mishandling. Thus, soil and water contamination stands out as a clear and direct consequence of improper disposal.
