" ... Although Carson never used the term, her passion was "sustainability." She envisioned harnessing the knowledge of biological diversity—entomology, pathology, genetics, physiology, biochemistry, and ecology- to shape a new science of biotic controls that would help control weeds, diseases and pests without further damaging the environment. Her dream of a science-based agricultural system may come as a surprise to those who believe that sustainability and technology are incompatible. ... "
" ... Birds are important indicators of ecological health, thus, this sweeping loss of birds -- especially common species -- indicate that a comprehensive ecological and environmental unraveling is underway. These losses indicate that severe, widespread biotic changes and ecosystem impacts are echoing throughout the entire food web, including pollinators, predators and prey. Basically, wild birds are unwitting (and unwilling) canaries in North America’s ecological coal mine. ... "
" ... Since Charles Darwin, wildlife biologists have suggested that interactions between species are strongest at the equator. This is called the so-called "biotic interactions" hypothesis and it has been used to explain, at least in part, why the tropics are so rich in species and diversity. The hypothesis looks at the interactions between species and how important that is for biodiversity. The idea of this hypothesis is that species interactions – such as those between predator/prey – increases the closer one gets to the species-rich equator. The stronger these interactions, the faster the evolutionary change, which then results in increased species diversity and a high level of biodiversity. ... "
" ... The European Space Agency’s (ESA) upcoming Exo-Mars rover will also be capable of searching for biotic organics; such as amino acids and fatty acids. And NASA’s Mars 2020 rover will also carry an instrument payload capable of seeking signs of habitable conditions on Mars and searching for signs of past microbial life. ... "
" ... We have missions going to look, and hopefully in the 2020s, we'll start to get answers that teach us whether our fantastical interpretations of signals like seasonal methane or organic molecules really hold up. They could be biotic in nature, and we won't know until we do the appropriate tests! ... "
