Learn about 5 ways the world has changed in the past 100 years. Without a doubt, humans have dramatically altered various facets of Planet Earth in a matter of centuries. As we mark Earth Day, it's worthwhile to reflect on 5 ways we have changed our planet in the last 100 years. Number 5 - The world's population in the year 1913 was about 1.8 billion. In just about a hundred years, the population has ballooned to over 7 billion. The world's largest cities have seen huge population spikes. Case in point, New York City's current population is estimated to be 8.2 million. In 1913, it was approximately 5 million and a hundred years prior, in 1813, just 70 thousand. Number 4 - Can you live without your phone, internet access, or tv? Not one of them was available to most people in 1913. It's a different world now. A recent report noted that 6 billion people have access to cell phones today, that's 1.5 billion more than the number of people who have access to clean toilets. While technology has numerous advantages, it also has a dark side. The US alone produces 50 million tons of e-waste every year and majority of it is not disposed off properly. Number 3 - In 1913, Henry Ford created the first automated assembly line for mass production of the automobile. Estimates show that there were about 1.1 automobiles registered in the US in 1913. In 2010, according to research gathered from Ward's, the worldwide number of motor vehicles in operation jumped over the 1 billion mark. Number 2 - Commercial air travel barely existed as the first commercial flight took place in 1914. In 2010, as reported by the US Department of Transportation, "815.3 million scheduled passengers traveled on U.S. airlines and on foreign airlines serving the United States in 2012." A commercial jet during a 10-hour international flight burns over 30,000 gallons of fuel. Number 1 - Human actions over the last 100 years may have impacted the planet's non-human residents more than humans themselves. In 2010, over 17,000 species were deemed vulnerable, endangered or critically endangered by a nature conservation group. Poaching and habitat loss are among the primary reasons. Take for instance, the lion population in Africa. A 2012 study found that the number of lions in the wild has fallen by 68 percent in the past 50 years, from an estimated 100 thousand in 1960, to just 35 thousand presently. On the other hand, some species are thriving due to higher pollutants. In the Chesapeake Bay, super crabs are wreaking havoc on the area's ecosystem. Crabs respond favorably to carbon resulting in them becoming bigger and possibly stronger.
了解世界已经改变，在过去的100年中的5种方法。毫无疑问，人类已经大大改变了地球的各个方面，在短短的几百年。在我们纪念“世界地球日”，这是值得反思在过去的100年中，我们已经改变了我们这个星球上的5种方法，第5号-世界人口在1913年为约1.8亿元。在仅仅约一百年，人口激增到超过7亿美元。世界上最大的城市已经看到了巨大的人口峰值。点的情况下，目前纽约市的人口估计为8.2亿元。在1913年，这是约5万元及一百年之前，在1813年，仅有70万。4号-你能生活在没有你的手机，互联网接入，或电视？他们没有一个人是在1913年的大多数人。现在这是一个不同的世界。最近的一份报告指出，60亿人有今天进入到手机，这是1.5十亿以上的人谁也获得干净的厕所数量。虽然技术有许多优点，它也有黑暗的一面。仅在美国生产50万吨的电子废弃物每年大部分是在不正确处置。第3号- 1913年，亨利·福特创建首个自动化流水线大批量生产的汽车。估计显示，有大约1.1汽车1913年在美国注册。在2010年，据考证聚集病房，全球营运机动车数量猛增超过1亿大关。2号-首次商业飞行发生在1914年几乎不存在商业空中旅行。2010年，由美国运输部报告，3,815.3百万元预定的乘客前往美国航空公司和外国航空公司在2012年美服“ 的商业飞机在10个小时的国际飞行超过30,000加仑的燃料燃烧。编号1 -在过去100年来人类的行为可能影响地球上的非人类的居民超过人类自己。在2010年，超过17,000种被视为脆弱，濒危或严重濒危的自然保护组。偷猎和栖息地丧失的首要原因。就拿，的狮子非洲人口。2012年的一项研究发现狮子在野外的数量已经下降了68％，在过去50年，在1960年估计有10万，目前仅有35万。另一方面，有些种类的蓬勃发展，由于较高的污染物。在切萨皮克湾，超级蟹肆虐该地区的生态系统。螃蟹积极回应碳导致他们变得更大，可能更强。
