E-waste represents a significant environmental challenge, exacerbated by rapid technological advancements and the short lifespan of many devices:

The impact of technology on the environment varies significantly by region and is influenced by local policies, technological adoption rates, and industrial activities.

The technology sector's environmental impact also has economic dimensions, particularly regarding energy consumption and the potential costs associated with carbon emissions and e-waste management.

Environmental damage is one of the most direct ways technology manifests its toxicity. Moreover, the manufacturing processes for electronic components expose workers to toxic substances, potentially leading to serious health issues. 

Electronic devices contain hazardous materials like lead, mercury, cadmium, and arsenic. When improperly disposed of, these substances can leach into the soil and water, causing significant environmental harm. In 2019 alone, the world generated an estimated 53.6 million tonnes of e-waste, but only a small fraction received proper recycling treatment. 

In addition, extracting rare earth metals and other materials necessary for electronic devices often leads to land, water, and air pollution. Mining activities can result in habitat destruction, biodiversity loss, and the spread of toxic wastes. For instance, producing a single smartphone can require up to 3,190 gallons of water. 

Beyond physical health and environmental impact, technology also introduces a form of toxicity that affects social interactions and mental health. The term "digital toxicity" encompasses the adverse effects of prolonged and unsupervised use of digital media and devices.
