enterprising of ecosystems. Ecosystem Degradation and Loss “Ecosystem degradation occurs when alterations to an ecosystem degrade or destroy habitat for many of the species that constitute the ecosystem” (Hunter & Gibbs‚ 2007‚ ch. 8‚ para. 4). An example of ecosystem degradation is deforestation for use as timber for humans that eliminates a natural habitat for a specific creature in that biota.

Habitat destruction is a main part of the problem but many animals are being killed and taken by hunters and poachers too. Many rare animals are hunted for food and even for sport. Some are caught alive and then sold on to collectors. One of the saddest and sickest reasons

Habitat Destruction Our planet is only able to foster life if its delicate balance is maintained. If this balance were to be disturbed‚ the results would be truly catastrophic. The destruction of the earth’s natural habitats is something that happens every day‚ and is a threat to its ecological balance. This type of destruction must be stopped because the state of our world as we know it is at stake. Forests‚ in particular‚ can be found all over the world and are a vitally important

number of Tigers on the planet falls between 3062 and 3948. Whereas the number of Tigers in the beginning of Twentieth century was about 1‚00‚000 . This shows that the Tigers are gradually declining. The main reasons for this are – Habitat destruction‚ habitat fragmentation and poaching. The Tigers are poached mainly for their skin (fur) which is used to make coats. The bones and nearly all parts of the Tiger are used in making traditional Chinese medicines. These Tigers were also a
