This is an odd question, although I suppose that the gases that are most affecting the animals near the Poles contribute indirectly. The gases you are referring to are called greenhouse gases, like carbon dioxide and methane. They don't so much affect the animals near the poles directly, but more the environment in which these animals live. The greenhouse gases contribute to the melting of ice caps and icebergs which, in turn, does affect polar animals like penguins and polar bears.
O2 in and CO2 out for animals, and the opposite for plants.
Natural gases is important
Oxygen.
There are many reasons why gases are important to us. For example, the air that we breathe is a gas.
Plants absorb water from the soil by osmosis and diffusion of water and gases is important for the inetercellular movement in plant and animal cells.
If evaporation was not in the water cycle then gases wouldn't be important. If gases weren't important then condensation wouldn't be important. And everything is important in the water cycle.
The most important gases in the air are nitrogen (around 78%) and oxygen (around 21%). These two gases are crucial for supporting life on Earth. Other gases like carbon dioxide and argon also play important roles in the atmosphere.

Natural gases are located in a few different places. Natural gases are in plants, animals and microorganisms that lived millions of years ago.
oxygen and carbon dioxide are the 2 most important gases for living things
