1 00:00:00,500 --> 00:00:30,239 Hello, I'm going to talk about the polar bear. The polar bear is the most wild, largest carnivorous mammal. They live in the northern hemisphere and they can eat 30 years. The weight of males is between 2 and 4 meters and their weight is between 350 and 700 kilograms. 2 00:00:30,500 --> 00:00:43,939 The female measure is between 1.8 and 2.4 meters and the reds are the lobes for walking and swimming. 3 00:00:43,939 --> 00:00:56,100 The skin of the polar bears is not white, it's black because the light reflected on the skin of the polar bear 4 00:00:56,100 --> 00:01:00,100 We can see that it is white, not black. 5 00:01:02,100 --> 00:01:08,099 They usually live in Greenland, Alaska and Canada. 6 00:01:09,099 --> 00:01:15,099 They feed on small seals and sometimes on brinders. 7 00:01:15,099 --> 00:01:28,099 They eat 30 kilograms and the only problem are humans that kill them. 8 00:01:28,099 --> 00:01:30,099 This is all. 9 00:01:30,099 --> 00:01:34,099 I am going to talk about the polar ecosystem. 10 00:01:34,099 --> 00:01:39,099 The polar ecosystem is divided in two parts, the Arctic and the Antarctic. 11 00:01:39,099 --> 00:01:42,099 They are also called the North Pole and the South Pole. 12 00:01:42,099 --> 00:01:58,599 The climate in Antarctica in winter is about negative 40°C and in summer negative 32°C. 13 00:01:58,599 --> 00:02:10,599 And in Antarctica in winter is negative 89°C and in summer negative 62°C. 14 00:02:12,099 --> 00:02:25,099 The difference between the Arctic and the Antarctic, there are lots of differences between the Arctic and the Antarctic but I am only going to talk about the difference of flora and fauna. 15 00:02:25,099 --> 00:02:37,099 The difference of fauna is that it lives, the bolivars live in the Arctic and penguins live in the Antarctic. 16 00:02:37,099 --> 00:02:44,099 And in flora, in the Arctic, it exists some plants, and no plants exist in the Antarctic. 17 00:02:44,099 --> 00:02:50,099 One protein in the Arctic is the producer, the algae. 18 00:02:50,099 --> 00:02:53,099 The primary consumer, the shrimp. 19 00:02:53,099 --> 00:02:56,099 The secondary consumer, the Arctic cod. 20 00:02:56,099 --> 00:03:00,099 And the tertiary consumer, the ring seal. 21 00:03:00,099 --> 00:03:04,099 And in the Arctic, the producer, the phytoplankton. 22 00:03:04,099 --> 00:03:10,099 the primary consumer, the quill, and the secondary consumer, the baleen quill. 23 00:03:10,099 --> 00:03:20,099 There are two threes of the Arctic and Antarctic, the oil and gas development and the climate change. 24 00:03:20,099 --> 00:03:28,099 Because of pollution, the ice from the Arctic and Antarctic is melting, 25 00:03:28,099 --> 00:03:39,099 So the sea level is rising and some islands, if we continue doing this, can disappear. 26 00:03:40,099 --> 00:03:48,099 And finally I'm going to talk about the tribes of persons in the Arctic, because in the Antarctic it doesn't exist anymore. 27 00:03:48,099 --> 00:04:04,979 The names are the Inuit, the Japi and the Alec. 28 00:04:04,979 --> 00:04:15,379 I am going to talk about recycling, that is one of the things we can do to try to save the environment. 29 00:04:15,379 --> 00:04:17,379 There are five types of bins. 30 00:04:17,379 --> 00:04:25,379 The organic one, that is the red one, and inside of this there is a mini hamburger. 31 00:04:25,379 --> 00:04:33,379 The paper and paper board, that is the blue one, and inside there we can put papers and 32 00:04:33,379 --> 00:04:35,379 paper boards of the things. 33 00:04:35,379 --> 00:04:40,379 The battery one, that is the white one, that is not the more common. 34 00:04:40,379 --> 00:04:44,379 We use it for the batteries that we can't use. 35 00:04:44,379 --> 00:04:54,560 The plastic one, that is the yellow one, we can use it for plastics that can be recycled 36 00:04:54,560 --> 00:04:59,060 for using another time that it was new. 37 00:04:59,060 --> 00:05:06,220 And the glass one, that is the green one, that inside there is a bottle of Coca-Cola 38 00:05:06,220 --> 00:05:07,220 of glass. 39 00:05:07,220 --> 00:05:18,220 You can recycle or later you can use another type of thing like the first time you use it. 40 00:05:18,220 --> 00:05:25,220 I am going to talk about protecting the environment, animals. 41 00:05:25,220 --> 00:05:28,220 The animals are very important for all. 42 00:05:28,220 --> 00:05:38,220 This is one bird that is in the year of extinction and there are only 16 birds like this. 43 00:05:38,220 --> 00:05:50,220 It lives in Mexico, in South America, North America and Canada and it's a terrestrial animal. 44 00:05:50,220 --> 00:06:00,220 This manatee is an aquatic animal and there are only ten manatees in Mexico. 45 00:06:02,220 --> 00:06:17,220 The habitats are very important for animals and when we are in parks we can't throw papers because the bears can't be there. 46 00:06:17,220 --> 00:06:19,220 And this is my problem. 47 00:06:20,220 --> 00:06:44,620 I'm going to talk about nutrition in an ecosystem. I'm going to start with producers. Plants, they make their own food from sunlight, water and mineral salts. Another type that they obtain from the soil. Another type of producers, they live in the aquatic ecosystem and it's called algae. 48 00:06:44,620 --> 00:06:57,620 Later we have the primary consumers. There are animals that take their energy from the plants. 49 00:06:57,620 --> 00:07:06,620 There are herbivorous animals. One of these examples are rabbits and mouse. 50 00:07:06,620 --> 00:07:16,620 Later we have secondary consumers. There are carnivores that take their energy from eating primary consumers. 51 00:07:16,620 --> 00:07:23,620 Later we have tertiary consumers. There are carnivores that they eat other carnivores. 52 00:07:23,620 --> 00:07:28,620 For example, a hawk eats owls. 53 00:07:28,620 --> 00:07:46,720 And later we have the predators. The predators may hunt the animals for food. The scavengers, they don't kill the animals, but they wait in a tree and later go down to eat them. 54 00:07:46,720 --> 00:07:57,220 And finally we have the parasites. The parasites, they don't kill anybody, but they are taking the blood of the mammals little by little. 55 00:07:57,220 --> 00:08:03,600 I am going to talk about how to protect the environment. 56 00:08:03,600 --> 00:08:09,600 The human is the principal cause of the extinction of the animals. 57 00:08:09,600 --> 00:08:16,600 We have cut lots of trees, polluted seas and burned lots of fossil fuels. 58 00:08:19,600 --> 00:08:25,600 We can protect the environment by not cutting lots of trees, 59 00:08:25,600 --> 00:08:36,600 not flowing rubbish to the seas and oceans, and not destroying the habitats of the animals. 60 00:08:36,600 --> 00:08:42,600 Now I am going to talk about six animals in the Andalusian Tension. 61 00:08:42,600 --> 00:08:47,600 One of them is the pink dolphin. 62 00:08:47,600 --> 00:09:04,899 This is one photo from the river of Amazonas. It is in danger of extinction because we destroyed their habitats. 63 00:09:04,899 --> 00:09:19,899 The adult is from 2.5 to 3 meters long and weighs from 110 to 200 kilograms. 64 00:09:19,899 --> 00:09:27,470 And now I am going to talk about the Philippine flying fox bat. 65 00:09:27,470 --> 00:09:30,470 This is one photo of him sleeping. 66 00:09:30,470 --> 00:09:55,139 It's in the station because some hunters hunt them for food and others hunt them for taking them for decorating their houses. 67 00:09:55,139 --> 00:10:08,480 They have them for that because they are the biggest bat in the world. 68 00:10:08,480 --> 00:10:12,480 They have... 69 00:10:17,789 --> 00:10:20,789 Now I am going to talk about the Green Macaw. 70 00:10:20,789 --> 00:10:24,419 This is one photo. 71 00:10:24,419 --> 00:10:36,419 It's in another station because the loss of items and the capital for trade eliminate them. 72 00:10:36,419 --> 00:10:50,929 It can be from 70 to 80 cm long and weights 900 grams approximately. 73 00:10:50,929 --> 00:11:07,960 And now I'm going to talk about the shark whale. The shark whale is in danger of extinction because we kill them with harpoons. 74 00:11:07,960 --> 00:11:27,200 It is the biggest fish in the world with a history of sixty hundred million years, near 75 00:11:27,200 --> 00:11:32,080 the age of the dinosaurs. 76 00:11:32,080 --> 00:11:39,080 Now, the next animal is the Tartuc Carreta or Giant Amarillo. 77 00:11:39,080 --> 00:11:42,080 This is one photo. 78 00:11:42,080 --> 00:11:57,519 It's in Daniel's distinction because the use of habitats and the hunt killed them. 79 00:11:57,519 --> 00:12:13,690 The last animal is in critical danger of extinction, is the Apistoma mexicano, this is the scientific name, the name is Ajolote. 80 00:12:16,690 --> 00:12:26,690 They can be albils, whites, white partials and dunes. 81 00:12:30,690 --> 00:12:43,490 the whites have dark eyes and the body all white the darks the aliens have all their body 82 00:12:46,350 --> 00:12:54,990 black with white eyes the white partials have the body white but have 83 00:12:54,990 --> 00:13:00,990 have green or black stains in their body. 84 00:13:00,990 --> 00:13:09,990 The tombs have a coloration of dark green or black. 85 00:13:09,990 --> 00:13:11,990 Now we're finished. 86 00:13:11,990 --> 00:13:14,990 I'm going to talk about the werewolf. 87 00:13:14,990 --> 00:13:19,990 This is an animal in the geophysicist because she suffered. 88 00:13:19,990 --> 00:13:33,990 He killed them because they ate their sheep and cows, and many people killed them for making clothes and eating them. 89 00:13:33,990 --> 00:13:38,990 There are only 408 brave wolves in the world. 90 00:13:38,990 --> 00:13:48,429 The brave wolf was declared an animal in the Jewish tradition in 1976. 91 00:13:48,429 --> 00:13:56,429 I talk about the protection of the terrestrial environment. 92 00:13:56,429 --> 00:14:06,429 The terrestrial environment, the most important factors are soil conditions and the terrain. 93 00:14:06,429 --> 00:14:19,289 Food chain is a group that is in the form of the produced, the primary consumer, the secondary consumer, and the tertiary consumer. 94 00:14:19,289 --> 00:14:33,470 The environment is the thing that is around that is affecting the people. 95 00:14:33,470 --> 00:14:52,470 The problem of environment is that the panda bear is in danger of extinction because the people catch the bamboo that the panda bear eats. 96 00:14:52,470 --> 00:15:16,470 In aquatic environment, the most important factors are salinity, the amount of light and the water current, 97 00:15:16,470 --> 00:15:25,470 and the temperature and the type of riverbed and seabed. 98 00:15:25,470 --> 00:15:45,470 Freshwater ecosystem contains very low water and salt. 99 00:15:45,470 --> 00:16:00,470 The marine ecosystem contains low levels of salt. 100 00:16:00,470 --> 00:16:05,470 And the last is the food webs. 101 00:16:05,470 --> 00:16:27,509 Food webs is more or less the food chain, but it's more different. It's a group that is more high that then you have more animals that eat them. It's more like a food chain but more high. 102 00:16:27,509 --> 00:16:36,509 I am going to talk about endangered animals. There is a fund called World Wildlife Fund 103 00:16:36,509 --> 00:16:50,509 that protects endangered animals and endangered plants. It was founded in 1916 by a French 104 00:16:50,509 --> 00:16:54,509 and the headquarters are in such lands. 105 00:16:54,509 --> 00:17:00,509 One of the endangered animals is the panda bear. 106 00:17:00,509 --> 00:17:10,509 There are less than 2,500 panda bears in the natural habitat. 107 00:17:10,509 --> 00:17:18,589 Panda bear is a special type of bamboo which takes 20 years to grow 108 00:17:18,589 --> 00:17:21,589 and a little bit more to bloom. 109 00:17:21,589 --> 00:17:31,589 So when men cut their branches, it takes a long time to grow. 110 00:17:31,589 --> 00:17:36,589 The most endangered animal is the Iberian lynx. 111 00:17:36,589 --> 00:17:43,589 There are only 200 Iberian lynx and they live in the Iberian Peninsula only. 112 00:17:43,589 --> 00:18:09,390 They die because of poisons, shoots and also accidents like when a car hit the links. 113 00:18:09,390 --> 00:18:13,390 There are many things we can do to save the planet. 114 00:18:13,390 --> 00:18:20,390 I have done this parade with boxes of free-range chickens. 115 00:18:27,420 --> 00:18:33,420 These chickens live in the open air and eat only natural things. 116 00:18:36,420 --> 00:18:39,420 I am going to talk about the burning of the forest. 117 00:18:39,420 --> 00:18:53,420 When people throw bottles on the forest, the sun hits the glass and it makes a magnified effect. 118 00:18:53,420 --> 00:19:01,420 It burns all around it, for example the leaves or the trees. 119 00:19:01,420 --> 00:19:07,420 This is bad because it destroys all the animal environment. 120 00:19:07,420 --> 00:19:15,420 Hello, my name is Mario Castro and I am going to explain my project, which is called the 121 00:19:15,420 --> 00:19:20,420 Earth and its problems. The Earth has got many problems and we have to search a solution 122 00:19:20,420 --> 00:19:27,420 to those problems that we are causing. Those problems are pollution, global warming, deforestation 123 00:19:27,420 --> 00:19:40,420 pollution and endangered species. Nowadays there are too much cars in the world, which 124 00:19:40,420 --> 00:19:48,420 contaminate the earth because of this smoke and carbon dioxide. Factories also produce 125 00:19:48,420 --> 00:19:55,420 carbon dioxide and smoke, but they aren't as harsh. They have got secretive certain 126 00:19:55,420 --> 00:20:07,019 which lead to sun lakes and rivers and oceans which contaminate the water and the animals 127 00:20:07,019 --> 00:20:12,420 which were there with chemical liquids. 128 00:20:12,420 --> 00:20:18,420 The global warming is the amount of carbon dioxide in the earth. 129 00:20:18,420 --> 00:20:31,420 When there is too much carbon dioxide in the earth, act like a cup which covers the earth and not let the heat from escaping. 130 00:20:31,420 --> 00:20:40,420 So the temperature of the earth is warming and warming, so the polar ice caps are going to melt, 131 00:20:40,420 --> 00:20:51,420 the sea level of water is going to increase and the small islands like the Canary Islands of Spain will disappear. 132 00:20:51,420 --> 00:20:55,420 Deforestation is the loss of forests. 133 00:20:55,420 --> 00:21:00,420 Forests are like the lamps of the earth because they produce oxygen. 134 00:21:00,420 --> 00:21:10,420 People cut down many trees for producing goods and paper, for making things and roads. 135 00:21:10,420 --> 00:21:24,420 But nobody thinks that if we cut all of those trees, the animals that inhabit on those trees could disappear because when they make the goods into small pieces. 136 00:21:24,420 --> 00:21:29,420 The endangered species are the species in dangerous extinction. 137 00:21:29,420 --> 00:21:44,420 This cause because, for example, with the panda bear, when we kill them, we take its skin with the expert to keep us warm. 138 00:21:44,420 --> 00:21:57,420 But with all of those, the pandas are in danger of extinction because more and more species of them are disappearing because of that. 139 00:21:57,420 --> 00:22:03,500 All of these problems have got solutions. 140 00:22:03,500 --> 00:22:15,299 In our day by day we can save electricity, water, fuel and recycle every day. 141 00:22:15,299 --> 00:22:24,079 Looking at the future I think we could build ecological houses or electric cars. 142 00:22:24,079 --> 00:22:28,119 so we could not contaminate so much the earth.
