Can tech kill or save the planet?
summary
Tech causes tangible harms and offers concrete fixes: digital already emits 3.8%–5% of global GHGs, data centers consume ≈1% of global electricity, and online video in 2018 matched Spain’s CO2 output; 34 billion connected devices and 53 million metric tons of e‑waste create supply‑chain and recycling crises while 90% of a smartphone’s energy cost occurs before purchase. Practical responses: measure footprints, apply eco‑design, low‑tech websites, device leasing and local repair, and prioritize materials‑efficient architectures.
