"I had to travel a long way to get to this habitat. First I went to the South Pole, which is in Antarctica and then I went to the North Pole in the Arctic. When I visited the Arctic it was in total darkness. Apparently the tilt of the Earth means that each pole has no sunshine for half the year and continual sunshine for the other half!"

"I have noticed differences between the Arctic and Antarctic. The Antarctic is a land mass which is permanently covered in ice and surrounded by ocean, whereas the Arctic is an ocean permanently covered in ice and almost entirely enclosed by land! This means the climate in Antarctica is colder than in the Arctic because land loses heat faster than oceans do."

"Despite the freezing conditions of Antarctica, I have found many different animals that have made this area their home. These include king penguins, emperor penguins, seals, whales, dolphins and over 200 species of fish. I've taken pictures of a fish called the bloodless fish, so called because it has no red blood cells and therefore its blood is completely clear!"

"The slightly warmer climate of the Arctic means that more food is available to a wider range of animals here and so you will find a lot more land-based animals in the Arctic compared to the Antarctic. It is here that you find the polar bear, the Arctic fox, the Arctic wolf and the walrus. It's still too cold for me though!"

"An important feature of the poles is that the seas are full of nutrients. The cold water is rich in minerals and has more oxygen and carbon dioxide than warmer water, which helps plant plankton grow. This plankton is an important ingredient for the whole of the marine food chain, on which many animals depend, from small fish to giant whales."

"Sadly these amazing polar landscapes are changing as a result of climate change. Scientists tell me that as your climate heats up, the Arctic and Antarctic ice caps are melting, threatening the lives of animals like the polar bear, which can only survive in these special conditions."

"Fortunately, my friends at WWF have told me that it's not too late to prevent the worst effects of climate change and save animals like the polar bear from extinction. The reason your planet is heating up is because of gases that are released into the atmosphere when people burn fuels like coal and oil to make energy, but there are alternatives that don't release such harmful gases."

"WWF is working with many organisations to try and stop climate change and reduce the impact it will have on the planet's wildlife. Its aim is to reduce these harmful gases and encourage alternatives that are better for the environment."
