The main cause of biodiversity loss has been habitat destruction ...

CONT

The loss of forest, wetlands, grasslands, and other habitats contributes to loss of biodiversity.

CONT

Invasive alien species are considered to be the most important threat to biological diversity loss after habitat destruction. All ecosystems - from forests and grasslands to marshes and coastal zones - are vulnerable to invasive alien species.

CONT

Habitat fragmentation is the loss and subdivision of portion of a given habitat and the corresponding increase in other habitats in the landscape. It is one of the most important contributors to the loss of biological diversity in temperate regions. Because of fragmentation, large populations are being broken into local populations, and this can lead to extinction if the local populations cannot interact.

CONT

La pérdida de biodiversidad es probablemente uno de los problemas científicos más importantes que tenemos que abordar en el Siglo XI. Bosques cortados y reducidos a su mínima extensión, transformaciones de tierras, cambios drásticos de usos del suelo, contaminación de suelos y aguas, sobreexplotación de recursos naturales, todo ello está llevando a la más grave extinción de biodiversidad que el hombre haya podido conocer a lo largo de su historia. Esta pérdida no sólo afecta a la vida silvestre (fauna y flora) sino a la diversidad genética cuyo ejemplo más cercano podemos encontrarlo en la desaparición de razas y variedades domésticas.

Wong and Brodo note that while it is possible that some of the very small lichens may have been overlooked, this is not the case for foliose and fruticose species, which are large and which appear to have completely disappeared in the past 60 years. This is a serious loss of biodiversity ...
