Wildlife species suffering decline

Some examples of species being affected, according to WWF:

Hedgehog populations declined by three quarters in UK urban areas between 2002-2014, thought to be due to habitat loss, pesticides reducing their prey and vehicle deaths.

African grey parrot populations in south-west Ghana decreased by 98% between 1992-2014 due to exploitation and habitat damage.

Global whale shark populations are thought to have fallen by more than 50% over the last 75 years.

African elephant populations in Tanzania have declined by 60% between 2009-2014, mostly due to poaching for their ivory.

Populations of black and white rhinos are down by an average of 63% between 1980-2006, with the illegal wildlife trade for their horns the biggest threat facing the animals.

Polar bear numbers are projected to decline by 30% by 2050, as climate change melts the Arctic ice.

More than 100,000 Bornean orangutans are estimated to have been lost between 1999 and 2015, largely due to the loss of their forest home and illegal hunting.

Puffin numbers in Europe, home to 90% of the seabirds, is projected to fall by 50%-79% between 2000-2065 due to climate change and overfishing.

Populations of the wandering albatross declined rapidly as the birds are accidentally caught in long-line fisheries.
