There are so many species which are in danger of extinction. All of them for indirect or direct human acts. One of these cases are polar bears: heavy mammals which live on Arctic. Recently, WWF and the US government have released a campaign to recover the population of this species.
It is truth that is necessary a bit more help to finish with the oil drilling and the climate change: the truth enemies of this species. However you can put a bit of your part not only caring of the planet if not signing this petition. Thank you for your time in advance.
