"She was last seen wearing a black t-shirt and grey pants.",Degrace was last seen on June 25 in the Ryerson Avenue and Bathurst Street area. Police highlighted that they are concerned for the person's safety.,However, what appears to be an effort to respect someone's preferred gender identity turned out to be confusing and borderline misleading for many people. Many users were quick to blast the police department over its call for public assistance being less than helpful.,© Photo : Twitter / @PatriotMike86ScreenshotScreenshot© Photo : Twitter / @PatriotMike86,© Photo : Twitter / @Sandervandam2ScreenshotScreenshot© Photo : Twitter / @Sandervandam2,Instead of trying to help search for the missing person, many people ended up engaging in a heated debate on trans rights.,© Photo : Twitter / @Serena_PartrickScreenshotScreenshot© Photo : Twitter / @Serena_Partrick,Others simply mocked the way Toronto Police requested public assistance.,© Photo : Twitter / @AF632ScreenshotScreenshot© Photo : Twitter / @AF632,The confusing tips on the missing person come as many view the Canadian Human Rights Act as potentially envisaging penalties for those who fail to use someone's preferred pronouns. Among such penalties could be mandatory sensitivity training, a requirement to issue an apology or a publication ban.。这是我国第一个三维印制生物标本。

B | 据报道,“齐琪”被认为是最后一只白海豚,在2002年被囚禁22年后死亡。3-D打印样本长2.07米,重约7公斤。它是从三维打印构建的“冰淇淋”三维数据模型中恢复出来的。据报道,“奇奇”是世界上最长的圈养海豚。

C | 1980年被渔民捕获并送往水生栖息地。自从2002年它死后,没有人见过活海豚。白鳍豚(学名:白鳍豚,lipotes vexillifer),又名:白鲸、白鳍、白旗、白夹、绿鳍、琵琶、中国鼠海豚、长江鼠海豚、长江河豚,是我国特有的淡水鲸种,只产于长江中下游。20世纪80年代,由于各种原因,海豚的数量急剧下降。2002年,据估计有不到50只海豚,被称为“水中大熊猫”。

D | 海豚属于自己的家族,被列为国家一级保护野生动物和世界上12种最濒危动物之一。2007年8月8日,一份报告发表在《英国皇家学会生物学快报》上,正式宣布了海豚的功能性灭绝。
