让我们拯救北极熊英语作文英文回答:Let's Save the Polar Bear.The polar bear (Ursus maritimus) is a large carnivorous bear that inhabits the Arctic Ocean and its surrounding seas. It is the world's largest bear species, with adult males weighing up to 1,500 pounds (680 kg) and adult females weighing up to 650 pounds (295 kg). Polar bears are well-adapted to their cold, icy environment. They havethick fur coats that insulate them from the cold, and their large feet and claws help them to distribute their weight evenly on ice.Polar bears are apex predators, meaning that they are at the top of their food chain. They primarily feed on seals, but they will also eat walruses, fish, and birds. Polar bears are ambush predators, and they will often wait patiently for their prey to come close before attacking.Polar bears are facing a number of threats, including climate change, habitat loss, and pollution. Climate change is causing the Arctic ice to melt, which is reducing the amount of habitat available for polar bears. Habitat loss is also occurring due to human activities, such as oil and gas exploration and development. Pollution is anotherthreat to polar bears, as they can ingest harmful chemicals through the food they eat.There are a number of things that can be done to help save polar bears. We can reduce our greenhouse gas emissions to help mitigate climate change, and we can support organizations that are working to protect polar bear habitat. We can also reduce our consumption of seafood to help reduce the demand for seals, which are a primary food source for polar bears.Polar bears are an important part of the Arctic ecosystem, and they deserve our protection. By taking action to help save polar bears, we can help to ensuretheir survival for generations to come.中文回答:让我们拯救北极熊。

倡议书保护北极熊

倡议书保护北极熊篇一:北极熊和动物保护Opinion column on polar bearNowadays, the polar bears are being hunted and are impacted by the climate change.The polar bears are killed mostly by local people and the hunt takes an important cultural role. The selling price of a polar bear is an important income for the local people. They get sum of money from the polar bear. Selling polar bears is a way the local people get money from. It’s such a golden jar to the local people.The hunting mostly occurs in Canada and the local people lives near the Arctic Ocean. Also the polar bears taken in hunts is used as food and in some communities. Even the Artic peoples havetraditionally hunted polar bears for food, clothing and some religiouspurpose.The polar bears have been hunted for thousands ofyears. In addition, the increasing temperature in the Arctic has change the population of the polar bear in some ways. Polar bears spend most of their lives on the sea ice of the Arctic Ocean and are classified as marine mammals. They have a thick layer of body fat and a coat that insulate them from the cold air and water. They use over 50% of their life hunting for foods, but less than 2% of their hunts are successful. And that make them need large amounts of fat to survive. That make them hard to survive.The total polar bear population is declining and there is a high risk of the future. Also polar bears have very low reproductive rates due to theirdelayed maturation. Their bodies are small, but they have high mortality. The low reproductive rates mean that the population growth rates are low and because of they have high mortality, there are less and less of them survive. WWF shows that if the population is greatly reducing in numbers, then it may take many years or even decades for the population to return to its original size. That shows that if we keep hunting the polar bears, it will be very fast for them to be extinct, that means we are losing one of the cutest marinemammals in the world and we are losing one of our friends. The polar bears as they are in the ecosystem, take a good place in theenvironment that we are living. Animals are our friend and it’s ourresponsibility to protect them. We don’t hunt them, but we can do things to stop hunting. We can stop buying things from the polar bear. We can stop buying the cloths make from the polar bears. And also we need to focus on the pollutions that causes the global warming which affected the polar bears.Works Cited"How to Help Polar Bears.Polar Bears International. N.p., n.d.

二年级童话两只小企鹅

两只小企鹅
一天,两只小企鹅在冰上玩。
突然,一只小企鹅掉进了冰窟窿,另一只小企鹅很着急,站在一边想办法。
小企鹅没办法,就一个劲儿的往上拽,掉进冰窟窿里的小企鹅也没办法,它就使出全身力气往上爬。
突然,掉进冰窟窿里的小企鹅似乎看见了什么,高喊着:“救救我!”小企鹅一看原来是一只北极熊。
北极熊说:“我才不帮你呢。
”北极熊边说边往冰窟窿上坐。
北极熊睡着了,冰窟窿也结冰了。
谁知,小企鹅拱破了冰面,北极熊掉进了冰窟窿。
北极熊从睡梦中惊醒过来,大喊:“快救救我!”小企鹅说:“不救,这叫恶有恶报。
”
最终,北极熊饿死在了冰窟窿里。
【三年级作文】救救黑熊

【三年级作文】救救黑熊
今天中午,我回到家,照常打开电视机,看12:30湖南卫视播出的《播报多看点》。
没想到,短短几十分钟的节目却让我整个下午的心情都沉重无比,痛得无法呼吸。
今天的节目是从活黑熊身上提取胆汁制成药物。
看到流动的画面,我的心似乎被堵住了,痛得无法呼吸。
每当我看到黑熊颤抖的身体和痛苦的表情,我都非常讨厌那些残忍的人。
钱真的那么重要吗?金钱真的能让一个人看着另一个人死去吗?我想如果黑熊会说话,他会毫不留情地指责人类的残忍和他自己的悲惨处境。
如果可以,我愿意代替黑熊承受痛
苦
节目还请到了国内外著名的公益团体——sos的负责人。
据他介绍,国内以黑熊胆汁
为原料做出药品不计其数,其实,早在20世纪中期,日本就掌握了人工合成黑熊胆汁的
技术,其营养价值不低于从黑熊身上提取的,我国也有十几家企业掌握了这项技术。
后来,他还说被企业提取胆汁的黑熊即使解救出来了,也活不了多长时间了。
我震惊了:难道黑
熊就没有享受幸福的权利吗?我们人类是父母生养的,黑熊和其他动物就不是父母生养的吗?人类赚钱的方法有千千万万种,难道一定只有黑熊胆汁才赚钱吗?如果真的是这样,
那么比尔8226;盖茨、巴菲特这些人的财富都是买黑熊胆汁赚来的吗?都说物以稀为贵,也许到了世界上最后一只动物是人类自己的时候,我们才会懂得珍惜吧……
春天不仅属于人类,也属于所有生物。
我只有一个愿望:拯救黑熊
救救黑熊……。
拯救北极熊的英语作文

拯救北极熊的英语作文英文回答:Saving polar bears is a crucial task for us to protect the environment. As the ice in the Arctic melts due to global warming, polar bears are losing their naturalhabitat and struggling to find food. If we don't take action to address climate change, the polar bear population will continue to decline.One way to help save polar bears is to reduce our carbon footprint. This means using less energy, driving less, and supporting renewable energy sources. For example, I have started biking to work instead of driving, and I make sure to turn off lights and electronics when they're not in use. These small changes can make a big differencein reducing carbon emissions.Another important step is to support organizations that are working to protect polar bear habitats. For instance, Irecently donated to a wildlife conservation group that is focused on preserving the Arctic ecosystem. Every littlebit helps, and it's important to show our support for these efforts.In conclusion, saving polar bears requires individual action and collective efforts. We all need to do our part to reduce our impact on the environment and support initiatives that aim to protect polar bear habitats.中文回答:拯救北极熊对于保护环境来说是至关重要的任务。

拯救北极熊英语作文初一

拯救北极熊英语作文初一Saving the Polar Bears.The Arctic, a vast and frozen landscape, is home to one of the most endangered species on Earth: the polar bear. These majestic creatures, with their thick white coats and powerful builds, have survived for thousands of years in the harshest of environments. However, their existence is now threatened by climate change and human activities. Itis our responsibility to take action and save the polar bears from extinction.The polar bear is a true survivor. They are adapted to the extreme conditions of the Arctic, with thick coats that keep them warm in the freezing temperatures and paws that allow them to walk on snow and ice. They are top predators in their ecosystem, preying on seals and other marine mammals. However, their way of life is being disrupted by the melting of the Arctic ice caps due to climate change.The melting ice is causing the polar bears' habitat to shrink, forcing them to travel longer distances in search of food. This not only makes it difficult for them to survive but also increases their interactions with humans, leading to conflicts and sometimes even attacks. The loss of sea ice also affects the polar bears' ability to reproduce. Female polar bears rely on the ice to give birth and nurse their cubs, but as the ice melts, this vital habitat is disappearing.In addition to climate change, human activities are also threatening the polar bears' survival. Commercial fishing, oil and gas exploration, and shipping in theArctic region are disrupting the bears' habitat and food sources. Pollution from these activities is also poisoning the marine environment, affecting the seals that the polar bears depend on for food.To save the polar bears, we need to take urgent action. We must reduce our carbon emissions to slow down climate change and preserve the Arctic ice caps. We also need to regulate human activities in the Arctic region to minimizetheir impact on the polar bears' habitat. This includes sustainable fishing practices, strict environmental regulations for oil and gas exploration, and reduced shipping traffic in the Arctic.Individuals can also play a role in saving the polar bears. We can reduce our carbon footprint by conserving energy, using public transportation, and purchasing energy-efficient products. We can also support organizations that are working to protect the polar bears and their habitat by donating money or volunteering.In conclusion, the polar bears are facing a gravethreat to their survival due to climate change and human activities. It is our responsibility to take action andsave them from extinction. By reducing our carbon emissions, regulating human activities in the Arctic region, and supporting conservation efforts, we can ensure that thepolar bears continue to thrive in their natural habitat.Let's come together and save the polar bears for future generations to enjoy.。

分布范围
顾名思义,北极熊生活在北极。它们把家安在北冰洋周围的浮冰和岛屿上,还有相邻大陆 的海岸线附近,基本呈环极分布。它们一般不会深入到更北端的地方,因为那里的浮冰太 厚了,连它们的最主要猎物——海豹也无法破冰而出,没有食物,北极熊自然不会去冒险。 生活在那里的北极熊被我们分为六大种群:俄罗斯弗兰格尔岛-阿拉斯加西部种群;阿拉 斯加北部种群;加拿大北极群岛种群;格陵兰种群;挪威斯瓦尔巴特群岛-俄罗斯法兰兹
