Plants' roles may be evil, as with the triffids, carnivorous plants with a whip-like poisonous sting as well as mobility provided by three foot-like appendages, from John Wyndham's 1951 science fiction novel The Day of the Triffids, and subsequent films and radio plays. [42] J. R. R.
The environmental impacts of nuclear power plant disasters such as the Chernobyl disaster, the Fukushima Daiichi nuclear disaster and the Three Mile Island accident, among others, persist indefinitely, though several other factors contributed to these events including improper management of fail safe systems and natural disasters putting ...
The human population exploits and depends on many animal and plant species for food, mainly through agriculture, but also by exploiting wild populations, notably of marine fish. [ 10 ] [ 11 ] [ 12 ] Livestock animals are raised for meat across the world; they include (2011) around 1.4 billion cattle , 1.2 billion sheep and 1 billion domestic pigs .
Plant blindness is also thought to have led to a deficit in plant science research and education. [1] Plant science research has been defunded, interest in botany majors has decreased, and plant biology courses have been terminated in recent years. [3] [7] Yet, this plant research is believed to be critical for medicinal and agricultural ...
Wildlife includes all non-domesticated plants, animals and other organisms. Domesticating wild plant and animal species for human benefit has occurred many times all over the planet, and has a major impact on the environment, both positive and negative. Wildlife can be found in all ecosystems.
Abiotic stress is the negative impact of non-living factors on the living organisms in a specific environment. [1] The non-living variable must influence the environment beyond its normal range of variation to adversely affect the population performance or individual physiology of the organism in a significant way.

Plants have some of the largest genomes of all organisms. [74] The largest plant genome (in terms of gene number) is that of wheat (Triticum aestivum), predicted to encode ≈94,000 genes [75] and thus almost 5 times as many as the human genome. The first plant genome sequenced was that of Arabidopsis thaliana which encodes about 25,500 genes. [76]
