This document discusses several technologies that can negatively impact the environment, including nuclear energy and petroleum/crude oil. Nuclear energy produces radioactive waste that is dangerous and difficult to store safely. While nuclear power is efficient, waste storage needs further development. Petroleum/crude oil releases carbon dioxide when burned and can lead to spills that pollute the air and water. However, we continue using oil-based fuels due to existing infrastructure and markets. The document examines pros and cons of these technologies and their effects on humans and the environment.
