  2. Laser safety - Wikipedia

    en.wikipedia.org/wiki/Laser_safety

    Laser radiation safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations.

  3. Injury in plants - Wikipedia

    en.wikipedia.org/wiki/Injury_in_plants

    Injury in plants is damage caused by other organisms or by the non-living (abiotic) environment to plants. Animals that commonly cause injury to plants include insects, mites, nematodes, and herbivorous mammals; damage may also be caused by plant pathogens including fungi, bacteria, and viruses. Abiotic factors that can damage plants include ...

  7. Human impact on the environment - Wikipedia

    en.wikipedia.org/wiki/Human_impact_on_the...

    The failure of noticing and appreciating plants is regarded as "plant blindness", and this is a worrying trend as it puts more plants at the threat of extinction than animals. Our increased farming has come at a higher cost to plant biodiversity as half of the habitable land on Earth is used for agriculture, and this is one of the major reasons ...

  8. Photoinhibition - Wikipedia

    en.wikipedia.org/wiki/Photoinhibition

    Lincomycin can be used to block protein synthesis. Photoinhibition is light-induced reduction in the photosynthetic capacity of a plant, alga, or cyanobacterium. Photosystem II (PSII) is more sensitive to light than the rest of the photosynthetic machinery, and most researchers define the term as light-induced damage to PSII.

  9. Ecological light pollution - Wikipedia

    en.wikipedia.org/wiki/Ecological_light_pollution

    Ecological light pollution [1] is the effect of artificial light on individual organisms and on the structure of ecosystems as a whole.. The effect that artificial light has upon organisms is highly variable, [2] and ranges from beneficial (e.g. increased ability for predator species to observe prey) to immediately fatal (e.g. moths that are attracted to incandescent lanterns and are killed by ...
