Biohazard Earth. Conceptual computer artwork of a biohazard sign (red) on the Earth, representing worldwide biological contamination. This could be due to biological warfare, or the spread of a new virus or bacterium that is pathogenic (harmful) to humans. Other microbes, like fungi and protozoans, can also be dangerous. Medical waste can also be harmful, while some genetically modified organisms (GMOs) could damage entire ecosystems.
