How animals can be safeguarded

Nevertheless, over the last few years, man has realised that the loss of some animal species can cause extremely serious damages to the natural course of the food chain, so he tried to help the species most at risk. Many animals, such as, for instance, the chamois and the ibex in Italy, have been brought back to their habitat through a "re-colonisation" operation. For instance, green areas have been extended to protect butterflies.
Disappearing animals cannot be hunted or traded. Scientists have thought of meeting the animals' needs by building up some communicating "corridors" within the forests and broken-up natural areas. When a natural area is divided up, corridors are dug out to let the animals move within the last pieces of habitat left. And some animal populations have been found to really move along these corridors and also use them to mate.
Nevertheless, even if some animals have got back on their feet, the survival of many species is still at risk. The attempt to protect species at risk within parks and wildlife sanctuaries is certainly positive.
