Transcript of Saving the Arctic Tundra Biome

Bryn Richmond and Savannah Kephart Saving the Arctic Tundra SAVE THE ARCTIC TUNDRA Often referred to as the "treeless plain" , the Arctic Tundra is located in the Northern hemisphere near the taiga belt. This biome is known for its long, freezing winters and short cool summers. One characteristic that the Tundra has is permafrost, or permanently frozen ground. In the winter the ground is always frozen and hard, but in the summer the ice melts causing the ground to become incredibly marshy and soggy. The average winter temperature is -34 degrees Celsius, while the average summer temperature is about 12 degrees Celsius. The permafrost that is melting contains huge amounts of Carbon, Methane and other harmful greenhouse gasses. Twice the amount of Carbon that exists in the atmosphere exists in the permafrost of the Arctic Tundra. When a substantial amount of permafrost is melted these gasses will be released into the air and will be extremely harmful to the health of all humans and animals. How Will this Affect us? To insure that the permafrost of the Arctic Tundra will not melt, we must take actions against Global Warming. When we drive our cars, we pollute the air causing the Earth to heat up. Instead of driving a car everywhere we go we can ride a bike, or walk. We can also buy locally made and locally grown products that don't have to be transported a long way, this will reduce the pollution in the air as well. Recycling and using fluorescent lightbulbs can also prevent Global Warming. If we take action in these small ways, then we can save the Tundra and save millions of lives. How can we take action to save the Arctic Tundra? So what is the Arctic Tundra? Animals of the Tundra The Arctic Tundra does have a relatively wide variety of Animal life. This biome includes herbivorous animals like caribou and squirrels, Carnivorous animals like wolves and polar bears, Migratory birds like ravens, falcons and loons and fish like cod and trout. The Arctic Tundra has a very short season of reproduction. Plant Life Even though no trees are supposed to exist in the Arctic Tundra, many plants still do thrive in this biome. Plants of the Arctic Tundra include Arctic Moss, the Arctic Willow, Bearberry, Caribou Moss, the Diamond-Leaf Willow, the Labrador-Tea, Pasque flower and Tufted Saxifrage. The Arctic Tundra has a short growing season and the plants learn to adapt to the poor nutrients and up to 100 mph winds. Is the Arctic Tundra in Danger? Due to rising temperatures, the layer of permafrost on this biome's surface is slowly melting, because of this trees are starting to grow on the once flat land of the Arctic Tundra. At rapid rates, the Arctic Tundra is disappearing and will soon be covered with trees. This will leave the Animals that live here to die and the Arctic Tundra to soon become the Boreal Forest. The shaded green areas are the areas where the Arctic Tundra is located around the world. The Polar bear is one of the animals that lives in the Arctic Tundra that can sustain its harsh weather conditions. The Arctic Tundra is heavily populated with wolves. Although Caribou used to fill the Arctic Tundra, they are now quickly reducing in number. Arctic Moss The Arctic Willow Tufted Saxifrage Although thought to be impossible before, the Arctic Tundra now has trees that range from 6 to 7 ft tall due to the permafrost slowly melting.
