The items listed on this page form part of the multi-page list of environment topics.This is a list of topics related (in whole or in part) to (a) phenomena in the natural environment which have a definite or significantly possible connection with human activity or (b) features of human activity which have a definite or significantly possible connection with the natural environment, even if the connection is made indirectly through the built environment. For example, hamster has been included because the effect on the built environment can affect the natural environment. Also, factory farming (often practiced indoors) has been associated with epidemics, which do not stay indoors.The connections can be positive (even remedial) or negative or both. Some introduced species intended to benefit the ecosystem have acted as invasive species, damaging the ecosystem. Also, different sources of energy development have both pros and cons. Furthermore, an environmental topic can be such for multiple reasons at one time, as in the case of resource extraction and processing; commodity distribution, use, and misuse; and waste management.Contents: F-Fal | Fam-Faq | Far-Faz | Fb-Fd | Fe-Fec | Fed | Fee-Feq | Fer | Fes-Fez | Ff-Fh | Fi-Fik | Fil-Fiq | Fir-Fird | Fire - Fire h | Fire i - Fire z | Fire (with hyphen) | Firea-Firez | Firf-Firz | Fis-Fisg | Fish (separate word) | Fish (with hyphen) | Fisha-Fishz | Fisi-Fisz | Fit-Fiz | Fj-Fk | Fla | Flb-Fln | Floa-Flon | Floo | Flop-Floz | Flp-Flt | Flu-Flun | Fluo-Fluz | Flv-Flz | Fm-Fn | Fo-Fooc | Food - Food d | Food e - Food n | Food o - Food z | Food (in compound words) | Fooe-Fooz | Fop-Foq | For-Ford | Fore-Forer | Fores-Foress | Forest | Foresu-Forzzz | Fos-Fot | Fou-Foz | Fp-Fq | Fr-Fra | Frb-Frd | Fre-Free | Fref-Frer | Fres-Frez | Frf-Frh | Fri | Frj-Frn | Fro | Frp-Frz | Fs-Ft | Fu-Fue | Fuf-Ful | Fum | Fun | Fuo-Fur | Fus-Fuz | Fv-Fz F-FalF1 hybrid (plant or animal)factory farmingFair Air Association of Canada (FAAC)Fair tradeFairchild Tropical Botanic Garden (in Florida in the US)Fairtrade certification (see "environmental standards" under Principles)fake fur (fun fur) (faux fur)(fake meat: see) meat analogueFalkland Island Fox ("extinct")fall streaks(fall wind) katabatic wind(fallout: 1 meaning selected from disambiguation page)nuclear falloutfallout shelterfalse economy (an economics topic with relevance to the environment) Fam-Faqfamily farmfamily farm hog penfamine (see also list of famines)famine in India(famine in Ukraine) Holodomor (in 1932-1933)(famine of Bengal: see) Bengal famine of 1943famine relief (see "environments" under Modern Relief)famine scalesfamines in Czech landsfamines in Russia and USSRfan (implement) (see under Solar powered fan)fan death (urban legend)(FAO) Food and Agriculture Organization (of the UN)FAO soil classification (World Soil Classification) Far-Fazfarm (see under History of farming)(farm machinery) agricultural machinery(farmed shrimp: see) shrimp farm (see under Diseases and under Ecological impacts)farmerFarmer's Almanac (reference book)farmhouse(farming) agriculture (see under Environmental problems)(farming policy) agricultural policy (see under Environmental Protection and Land Management and under Environmental programs)fascioliasis (infectious disease of herbivores and humans)fast breeder (fast breeder reactor) (FBR) (see under Proliferation)fast neutron reactor (fast reactor)Fast Oil Recovery (FOR)(fault ) geologic faultfault friction (in seismology)fault mechanics (in structural geology)fault scarp ("caused by an earthquake")fauna (animals)fauna and flora of IndiaFauna and Flora Preservation Society (renamed Fauna and Flora International) (originally, Society for the Preservation of the Wild Fauna of the Empire;
