Read the passage below carefully:
Across rapidly expanding African metropolitan areas, the informal recycling of electronic waste has long served as a vital economic lifeline for thousands of urban youths. Operating out of makeshift scrap yards, these informal recyclers manually strip abandoned computers, televisions, and mobile devices to extract valuable metallic components such as copper, gold, and aluminum. However, this crude processing relies heavily on open-air burning of plastic cables and acid bath leaching, releasing toxic heavy metals, lead, and dioxins into surrounding soil and groundwater networks. To mitigate these severe environmental and public health hazards without crippling local livelihoods, environmental scientists are advocating for the transition to integrated eco-industrial recycling hubs. These specialized facilities combine decentralized informal collection networks with state-of-the-art mechanical shredding and hydrometallurgical processing technology. By formalizing the sector, municipal authorities can safeguard recycling workers through occupational protective equipment, eliminate toxic atmospheric emissions, and capture a significantly higher percentage of high-purity rare earth minerals. Ultimately, integrating informal collectors into modernized, ecologically sound processing systems offers a sustainable model that preserves urban livelihoods while effectively eliminating the toxic environmental footprint of electronic waste.
Which of the following statements best expresses the essential idea of the passage?
- Integrating informal e-waste collectors into modernized recycling facilities provides a sustainable solution that protects both livelihoods and the environment.Answer
- BInformal recyclers extract valuable minerals such as copper, gold, and aluminum by manually stripping discarded electronic devices.
- CBanning informal waste collectors is the only effective strategy for eliminating toxic atmospheric emissions in urban centers.
- DMechanical shredding technology has failed to recover high-purity rare earth metals from abandoned computers and mobile phones.
