Gấu Bắc Cực đang đứng trước nguy cơ tuyệt chủng. Khác với các loài bị đe dọa tuyệt chủng khác, vấn đề không phải do săn bắt mà là bởi biến đổi khí hậu. Từ năm 1979, mỏm băng ở Vòng Cực Bắc nơi gấu Bắc Cực sing sống đã giảm 30% kích thước. Nhiệt độ ở Bắc Cực đã và đang tăng dần và điều này khiến băng tan chảy, đe dọa nơi cư trú của loài gấu. Nguồn thức ăn chính của gấu Bắc Cực là các loài hải cẩu khác nhau ở vùng Bắc Cực. Chúng săn mồi bằng cách đợi bên các hố thở mà hải cẩu tạo trên băng. Dù gấu có thể bơi rất khỏe, chúng không bao giờ bắt được hải cẩu dưới nước. Điều này có nghĩa loài gấu hoàn toàn phụ thuộc vào băng để săn mồi. Gấu Bắc Cực cũng cần băng để di chuyển. Chúng có thể hoạt động trên một vùng lãnh thổ rộng lớn và thường bơi từ rìa băng này sang rìa băng khác. Chúng được biết có thể bơi xa tới 100km, nhưng khi băng ít đi, chúng hải bơi xa hơn và điều này có thể gây nguy hiểm đến tính mạng của loài gấu. Nhiều gấu Bắc Cực đã chết đuối trong vài năm trở lại đây và các nhà khoa học tin rằng đó là do chúng không thể tới được băng trước khi kiệt sức và không còn khả năng bơi xa hơn.

The word robot first appeared in a 1921 stage play by Czech writer Karel Capek. In the play, a man makes a machine that can think, which he calls a robot and which ends up killing its owner. In the 1940s, the American science fiction writer Isaac Asimov wrote a series of stories about robots and invented the term robotics, the science of robots. Meanwhile, in the real world, the first robots were developed by an engineer, Joseph F. Engelberger, and an inventor, George C. Devol. Together they started Unimation, a manufacturing company that produces the first real robot in 1961, called the Unimate. Robots of this type were installed at a General Motors automobile plant and proved to be a success. They worked reliably and saved money for General Motors, so other companies were soon acquiring robots as well.
These industrial robots were nothing like the terrifying creatures that can often be seen in science fiction films. In fact, these robots looked and behaved nothing like humans. They were simply pieces of computer-controlled machinery, with metal “arms” or “hands”. Since they were made of metal, they could perform certain jobs that were difficult or dangerous for humans, particularly jobs that involve high heat. And since robots were tireless and never got hungry, sleepy, or distracted, they were useful for tasks that would be tiring or boring for humans. Industrial robots have been improved over the years, and today they are used in many factories around the world. Though the use of robots has meant the loss of some jobs, at the same time other jobs have been created in the design, development, and production of the robots.
