想象一下小北極熊，其母親被水包圍。只有一小塊冰塊在他們腳下漂流。冰慢慢地分開了。小北極熊漂移了，聳了聳肩。發(fā)抖并用水浸濕，卷曲起來。隨著小冰山慢慢越來越小，母親越來越近。幾英里附近沒有冰。母親需要找到食物，但是她已經(jīng)疲憊了，試圖讓她的孩子活著。 2016年12月，二十五個冰川減少到十五個，為什么會這樣呢？重視氣候變化和全球變暖，人類需要采取行動，因為它改變了自然，動物和人類。氣候變化影響人類的健康，可以使動物瀕臨滅絕或滅絕。雖然放緩全球變暖的進程緩慢，可能是一項艱巨的任務，但人們還需要采取行動以免為時過晚。
我們的環(huán)境是我們生活的重要組成部分。大多數(shù)人甚至不知道導致氣候變化是人類。由于我們的行動，動物和所有的自然都受到負面影響。根據(jù)“氣候變化的影響”，“地球的南北四極對于調(diào)節(jié)地球的氣候至關重要”。兩極都特別容易受到全球變暖的影響，影響整個地區(qū)或整個地球。融化的冰川極大地影響著我們世界的淡水生態(tài)系統(tǒng)。海洋和河流的水位正在上升，也吸收了二氧化碳氣體，以防止其流向大氣層。全球變暖增加了“二氧化碳濃度使海洋更酸性”。海洋中的海洋生物可能滅絕或被破壞。植物可以隨著溫度和碳水平急劇變化而死亡，而其他生物需要在海洋，湖泊和河流中適應和生存。 “溫暖的空氣可以保持較高的含水量”，這意味著隨著水位的不平衡，干旱，極端天氣模式和洪水可能發(fā)生。淡水生態(tài)系統(tǒng)被“排水，疏浚，攔水，污染和開采”所制定，這些都是人類的行為。這些行動進一步加強了天氣的負面影響。天氣模式影響某些地區(qū)的植物或自然物種。根據(jù)氣候變化的影響，雪豹，犀牛，大象，北極熊和更多的動物也受到影響，“氣候變化發(fā)生得太快，許多物種都適應”。動物的領土一直在萎縮，由于海上升水平或融化的冰川，讓動物搜尋新的地區(qū)住房或可能滅絕。一些動物依靠氣候變化影響的天氣模式。 “敏感的珊瑚和藻類”是“從氧氣中餓死”的。這意味著珊瑚可以漂白或可能滅絕。動物依賴珊瑚和藻類食物，棲息和隱藏于捕食者身上。這些都是由于動物受到的氣候變化而造成的后果。
此外，有些人認為動物是唯一受影響的人，但人類也受到影響。人類并沒有意識到他們正在做的一切都在摧毀自己。根據(jù)氣候變化的影響，一項研究是由于氣候變化導致的極端天氣死亡人數(shù)已經(jīng)增加了多年。建筑物和城鎮(zhèn)的損壞每年需要數(shù)十億美元來替代用品和建筑物。極端事件的準備也增加了成本。在洪水或其他極端事件發(fā)生后的許多地區(qū)，人們紛紛涌入新的土地進行定居和緊急關注。根據(jù)全球變暖影響，由于“極熱，災害，疾病，空氣質(zhì)量，空氣中的二氧化碳”等因素，人們的健康也受到影響。我們生產(chǎn)的危險化學品會破壞大氣中的臭氧層，保護我們免受有害的陽光。陽光中有害元素會引起熱浪和干旱。人類的呼吸和心血管功能衰竭都是空氣污染的結果，也是引起哮喘或過敏等癥狀。根據(jù)氣候變化的影響，“內(nèi)部溫度控制的喪失可能導致一系列疾病”。增加溫室氣體可引起熱中風，熱痙攣，熱耗竭和高熱。在極端寒冷中，會發(fā)生凍傷和體溫過低。已經(jīng)經(jīng)歷氣候變化的地區(qū)的強度增加，導致更危險的疾病和健康影響。極端天氣的突然變化不允許人們適應。心理上，氣候變化引起焦慮，壓力，抑郁和自殺。社會關系緊張，壓力障礙加劇，侵略，暴力或犯罪行為。這些都是我們不小心采取行動的后果。
另一方面，減緩氣候變化需要無數(shù)的時間和手段。人們需要現(xiàn)在采取行動，而無力解決它。根據(jù)國家地理雜志，如果我們不顧一切地留下這個問題，即使我們結束氣候變化，改變的事情也許會停留。當北極冰川融化時，他們再也不會突然出現(xiàn)。如果冰川消失，生活在北極的動物如海象，北極熊和海豹都不能永遠游動。不僅在北極，還有其他動物因溫度變化而失去家園，不能適應。除非我們開始放緩氣候變化，否則環(huán)境的一個行動，如融化多年凍土，可能導致一系列事件，使氣候變化更加致命。多年凍土“釋放二氧化碳和更有效的甲烷”。多年凍土是冰冷的，冰凍的地面已經(jīng)困了碳數(shù)千年。這個過程更加惡化氣候變化。其他人說這只是一個問題，我們可以隨時修復，永凍層只是一個問題。氣候變化還有很多其他問題。水滴降低，瀕危動物，滅絕動物，枯萎自然。
因此，所有這些問題都是從人們開始的，所以人類是解決這個問題的?；旧?，人們需要停止或至少減緩全球變暖對地球的利益。全球變暖以許多不同的方式影響世界，例如造成動物滅絕并影響人類本身。人們可以很輕松地幫助環(huán)境，拯救許多生物。人們可以采取的行動是針對氣候變化，在家里節(jié)約能源，停止使用空調(diào)，甚至不要浪費食物的東西。全球變暖是一個嚴重的問題，人們現(xiàn)在需要采取行動，否則太晚了！
Imagine a polar bear kit and its mother surrounded by water. Only a tiny piece of ice was drifting under their feet. The ice was slowly breaking apart. The kit drifts away, squeaking with terror. Shivering and drenched with water, the kit curled up. The mother edges closer as the tiny iceberg was slowly getting smaller and smaller. No ice was near them for miles. The mother needed to find food, but she was already exhausted, trying to keep her kit alive. One hundred and fifty glaciers have been reduced to twenty five in the December of 2016. Why is this happening? Climate change and global warming need to be taken seriously and humans need to act now because it changes nature, animals, and humans. Climate change affects human health and can make animals endangered or extinct. Although the process of slowing down global warming is slow and can be an arduous task, people still need to take action before it’s too late.
?Our environment is a big part of our lives. Most people aren’t even aware that humans are the ones that are causing climate change. Thanks to our actions, animals and all nature are being affected negatively. According to The Effects of Climate Change, “Earth’s north and south extremities are crucial for regulating our planet’s climate”. The poles, especially, are vulnerable to global warming and the impacts of it can affect an entire region or the entire globe altogether. Melting glaciers greatly impact our world’s freshwater ecosystems. Ocean and river water levels are rising, which are also absorbing carbon dioxide gas to prevent it from reaching toward the atmosphere. Global warming has increased “carbon dioxide concentration which make oceans more acidic”. ?Sea life in the ocean could go extinct or be damaged. Plants could die as temperatures and carbon levels change drastically while other organisms need to adapt and survive in oceans, lakes, and rivers. “Warmer air can hold a higher water content,” which means as water levels become unbalanced, droughts, extreme weather patterns, and flooding can occur. Freshwater ecosystems are contrived by “drainage, dredging, damming, pollution, and extraction,” which are all acts of human beings. These actions furthermore strengthens the negative impacts of weather. The weather patterns affect plant or nature species in certain regions. According to The Effects of Climate Change, snow leopards, rhinos, elephants, polar bears, and many more animals are also being affected and “climate change is happening too quickly for many species to adapt.” Animal’s territories have been shrinking due to rising sea levels or melting glaciers, leaving animals to search new areas to shelter or possibly going extinct. Some animals depend on weather patterns, which are affected by climate change. The “sensitive coral and algae” are “starved from oxygen”. This means that coral can bleach or possibly become extinct. Animals depend on coral and algae for food, shelter, and to hide from predators. These are all the consequences due to climate change that is animals are affected by.
?Furthermore, some think animals are the only ones affected, but humans are being affected too. Humans don’t realize that everything they are doing are destroying themselves as well. According to The Impacts of Climate change, a study had been about the amount of deaths from extreme weather that had risen over years, due to climate change. Damage to buildings and towns need billions of dollars to replace supplies and structures each year. The preparation of the extreme event also add on the cost. In many regions after flooding or other extreme events, it sends people swarming for new land to settle in and emergency attention. According to Global Warming Affects, people's health are also affected due to “extreme heat, disasters, diseases, air quality, and carbon dioxide amounts in the air”. The dangerous chemicals that we produce break the atmosphere’s ozone layer that protects us from harmful sunlight. Harmful elements in sunlight causes heat waves and droughts. Human’s respiratory and cardiovascular failures are all results of air pollution, also causing conditions like asthma or allergies. According to Impacts of Climate Change, “Loss of internal temperature control can result in a cascade of illnesses.” Increasing greenhouse gases can cause heat strokes, heat cramps, heat exhaustion, and hyperthermia. In extreme cold, frostbite and hypothermia can occur. Areas that are already experiencing climate changes have increased intensity, causing more dangerous diseases and health effects. Abrupt changes in extreme weather do not allow people to adapt if they could. Mentally, climate changes cause anxiety, stress, depression, and suicidality. Social relationships can strain, stress disorders can strengthen, and aggression, violence, or crimes can be performed. These are all consequences of our careless actions that we are committing too.
?On the other hand, to slow down climate change comes with a price and a myriad of time and tactics. People need to act now while it is within out power to fix it. According to National Geographic, if we leave this problem carelessly, things that changed might stay, even if we end climate change. When arctic glaciers melt, they never just suddenly appear with a snap again. Animals that live in the arctic such as walruses, polar bears, and seals can’t swim forever if the glaciers fade away. Not just in the arctic, but other animals are losing their homes due to temperature changes that they can’t adapt to. Unless we start slowing climate change, one action of the environment, such as the melting permafrost, it can lead to a chain of events, making climate change even more deadly. Permafrost “releases carbon dioxide and more potent methane”. Permafrost is icy, frozen ground that has trapped carbon for thousands of years. This process worsens climate change even more. Others say that it’s just a problem that we can fix anytime, permafrost is only one problem. There are many other problems about climate change. Water ph levels lowering, endangered animals, extinct animals, and withering nature.
Therefore, all of these problems had started with people, so humans are the ones to fix it. Essentially, people need to stop or at least slow down global warming for the good of the planet. Global warming affects the world in many different ways, such as causing animal extinctions and affecting humanity itself. One could easily do much to help the environment, saving many organisms. Actions people can take are speaking up against climate change, saving energy at home, stop using air conditioning, or even something as easy as not wasting food. Global warming is a serious problem, and people need to take action now before it's ?too late!
