How Do Plant Species Go Extinct?

[Reeii Education]

Many scientists make a point of distinguishing between species that naturally occur in small, isolated populations and those that have been fragmented and diminished by human activity. Plant species that were once widespread, interbreeding, and diverse are most sensitive to declines in genetic variation associated with restrictions in range or population size. Loss of habitat prohibits buildup of population numbers from periodic lows. A habitat or population fragment is a smaller target for incoming seeds being dispersed from another habitat patch; therefore, recolonization may be problematic.

The most common cause of plant habitat loss and subsequent plant rarity and endangerment is the conversion of native plant habitat to cities, farms, roads, and regulated-flow river systems and reservoirs. Which mean plant extinction caused by human. Animal extinction also caused by humans. What more courses is by us??

 

[Snorrie]

Agriculture, suburban landscaping and housing expansion, the expansion of cities and related infrastructures are necessary for human survival, an economy and the spread of non-native plant/animal/other species as well as causing some plant species extinctions. We are a functioning integral part of Evolution for better or worse. Consider that the eventual lack of genetic diversity in multiple plant food species my put humans at a marked risk of widespread starvation. E.G.: the Irish Potato Famine. Consider also that "wild places" currently experiencing human destructive intrusions like the Amazon harbor both potential human medicines and pathogens. "We see the problem and it is us".
