Koala, l’Australia lo inserisce nelle specie minacciate

di Redazione 47

I koala tornano ad essere in pericolo 60 anni dopo la cancellazione dalla lista delle specie in via di estinzione. Lo ha deciso il Governo australiano che ha definito questo marsupiale “specie gravemente minacciata in alcune parti del Paese”. In particolare nelle zone del Queensland, New South Wales e nel Territorio della Capitale i koala sono stati inseriti nell’elenco nazionale delle specie vulnerabili.

A minacciare questo bellissimo animale è come sempre l’uomo. In parte direttamente, con l’espansione urbana, ed in parte indirettamente a causa dei cambiamenti climatici. Queste due concause hanno portato ad un declino del 40% degli esemplari negli ultimi 20 anni all’interno delle aree sopra elencate, e questo ha reso obbligatoria la registrazione nell’elenco.

Tony Burke, ministro dell’Ambiente australiano, ha personalmente guidato la battaglia per la salvaguardia dei koala, ed ha effettuato una relazione al Parlamento per spiegare il problema. Tra le principali minacce, oltre a quelle già elencate, Burke ha segnalato anche alcune malattie che starebbero decimando la popolazione, e l’attacco degli animali domestici, come i cani che li vedono come delle minacce. Purtroppo questo fenomeno è molto comune d’estate, quando la siccità miete molte vittime in Australia, ed i koala sono attratti dalle piscine e dalle ciotole dei cani. Purtroppo, essendo animali lenti nei movimenti, non fanno in tempo a scappare quando vengono attaccati dai proprietari di quell’acqua.

Si starebbe così ricreando lo stesso fenomeno avvenuto all’inizio del secolo scorso quando la colonizzazione degli europei portò l’intera razza dei koala sul limite dell’estinzione. All’epoca fu evitata per miracolo, ma ora dobbiamo fare i conti con altri tipi di problemi. A dare ragione al ministro australiano c’è anche l’IUCN che ha spiegato come, a causa dell’aumento della CO2 nell’atmosfera, il valore nutrizionale degli eucalipti, la principale fonte di sostentamento dei koala, sia diminuita, tanto da far rientrare questo animale tra le 10 specie maggiormente a rischio per i cambiamenti climatici.

  15. Zune and iPod: Most people compare the Zune to the Touch, but after seeing how slim and surprisingly small and light it is, I consider it to be a rather unique hybrid that combines qualities of both the Touch and the Nano. It’s very colorful and lovely OLED screen is slightly smaller than the touch screen, but the player itself feels quite a bit smaller and lighter. It weighs about 2/3 as much, and is noticeably smaller in width and height, while being just a hair thicker.

  18. This is getting a bit more subjective, but I much prefer the Zune Marketplace. The interface is colorful, has more flair, and some cool features like ‘Mixview’ that let you quickly see related albums, songs, or other users related to what you’re listening to. Clicking on one of those will center on that item, and another set of “neighbors” will come into view, allowing you to navigate around exploring by similar artists, songs, or users. Speaking of users, the Zune “Social” is also great fun, letting you find others with shared tastes and becoming friends with them. You then can listen to a playlist created based on an amalgamation of what all your friends are listening to, which is also enjoyable. Those concerned with privacy will be relieved to know you can prevent the public from seeing your personal listening habits if you so choose.
