Animals in extinction

Often we read articles about endangered species. The problem nowadays is serious since there are a lot of factors that threaten the animals. First of all, poachers kill animals like bears for their fur and elephants for their ivory. Climate change also affects animals because the environment deteriorates for them. For instance, if global temperature rises the ice of Antarctica melts and this is not convenient for seals and sea elephants. Water pollution and other waste also worsens animals' life. Fortunately, conservationists and people who love animals act against all these dangers. They organise campaigns in order to inform the public about the problem and its roots. Furthermore, they protect some species by feeding and assist them to reproduce.
