Answer:Many materials have both beneficial and harmful effects on the environment. For example, air conditioners provide cooling comfort but contribute to air pollution and climate change through refrigerant emissions. Similarly, while soap aids in hygiene, its overuse can pollute water sources. The production and use of plastics offer convenience, but plastic waste pollutes land and oceans, harming wildlife. Industrial factories produce goods essential to modern life, but their emissions contribute significantly to air and water pollution. Even tires, while necessary for transportation, eventually become waste that pollutes the environment if not properly recycled. Therefore, responsible use and disposal of these materials are crucial to minimize their harmful effects and maximize their benefits.
