Benzene is both a boon and a hazard. Explain how industries can balance economic benefits with ethical responsibility toward worker health and environmental safety.

Industries must balance profit with responsibility. While benzene is vital for producing plastics, detergents, and medicines, its toxic nature demands strict safety protocols. Ethical responsibility means protecting workers with safety gear, reducing emissions, and investing in greener alternatives. Economic growth should never come at the cost of human health or environmental sustainability.
