🌱 Quick Study Guide: Environmental Impact of Computing
- 🗑️ E-waste: Refers to discarded electronic devices containing toxic materials like lead, mercury, and cadmium, posing significant disposal challenges and health risks.
- ⚡ Energy Consumption: Computing, from data centers to personal devices and manufacturing, demands vast amounts of electricity, often generated from fossil fuels, contributing to greenhouse gas emissions.
- 💨 Carbon Footprint: The total greenhouse gas emissions caused directly and indirectly by the manufacturing, use, and disposal of computing hardware and software.
- ⛏️ Rare Earth Elements (REEs): Essential metals used in modern electronics, whose mining processes frequently lead to habitat destruction, soil erosion, and water pollution.
- ⏳ Planned Obsolescence: An industry practice where products are intentionally designed to have a limited lifespan or become quickly outdated, encouraging frequent upgrades and increased waste.
- ♻️ Green Computing & Sustainability: Strategies aimed at minimizing the environmental impact of computing, including using energy-efficient hardware/software, promoting recycling, leveraging renewable energy, and virtualization.
- 📚 AP CSA Connection: Understanding these impacts is crucial for grasping the broader societal and ethical implications of computing, a key component of the AP Computer Science A curriculum.
