Climate of Britain is attracting several foreign species. According to Sir David Attenborough, wildlife presenter, the foreign species should be allowed to thrive there.

While addressing a nature conference in London, Attenborough said that it is the time to accept the impacts of climate change. Northerly migration of animals is embracing the effects of climate change. The animals seeking cooler place are migrating.

According to Sir David, Britain is unsullied by human action and to avoid decline in wildlife, it is necessary to take this kind of step.

David Attenborough said that in 1945, the way to conserve wildlife was to create nature reserves and wildlife parks. Today, there are not enough parks and nature reserves. To avoid a devastating decline in wildlife, it is important to make whole countryside available for wildlife. Roadside verges, suburban garden and several other options must be used, he said.

While responding the Climate Change reports, Attenborough said that it's no time to discuss whether or not climate change is man-made. Today's argument is 'how to deal with it'.

He said population of hedgehog, spiny mammals of the subfamily Erinaceinae, has declined 50% in last 25 years, 90% of wildlife meadows, field habitat vegetated by primarily grass, have disappeared in 100 years. Apart from that, 60% of wildlife is in danger and 10% of it is considered to disappear in future.

David Attenborough said, "We know climate change is happening. It is regretted by some but it is also to be embraced. It is causing great changes in the distribution of animals and birds in the countryside. We must take advantage of that".

Earlier, biologist EO Wilson had said that half of the world should be set aside for the use of wildlife.
