    郝处俊,安州安陆人。甫十岁而孤,故吏归千缣赗之,已能让不受。及长,好学,嗜《汉书》,崖略暗诵。贞观中,第进士,解褐著作佐郎,袭父爵。兄弟友睦,事诸舅谨甚。召拜太子司议郎,累迁吏部侍郎。高丽叛,诏李勣为浿江道大总管,处俊副之.师入虏境,未阵,贼遽至,举军危骇。处俊方据胡床,体胖,安餐不顾,密畀料精锐击之,虏却,众壮其谋。入拜东台侍郎。时浮屠卢伽逸多治丹,曰“可以续年”。高宗欲遂饵之,处俊谏曰:“修短固有命,异方之剂,安得轻服哉? 昔先帝诏浮屠那罗迩娑寐案其方书为秘剂,取灵花怪石,历岁乃能就。先帝饵之,俄而大渐,上医不知所为,群臣请显戮其人,议者以为取笑夷狄,故法不得行。前鉴不远,惟陛下深察。”帝纳其言。

    上元初,帝观酺翔鸾阁,时赤县与太常音技分东西朋,帝诏雍王贤主东,周王显主西,因以角胜,处俊曰:“礼所以示童子无诳者,恐其欺诈之心生也。二王春秋少,意操未定,乃公朋造党使相夸,非所以导仁义,示雍和也。”帝遽止,叹曰:“处俊远识,非众臣所逮。”帝多疾,欲逊位武后,处俊谏曰:“昔魏文帝著令帝崩不许皇后临朝今陛下奈何欲身传位天后乎天下者非陛下之天下正应谨守宗庙传之子孙不宜持国与人以丧厥家。”事遂沮。开耀元年卒,年七十五。帝哀叹其忠,举哀光顺门,祭以少牢,赙绢布八百段、米粟八百石,诏百官赴哭,官庀葬事。子北叟固辞,未听。裴炎为白帝曰:“处俊阽死,诿臣曰:‘生无益于国,死无烦费,凡诏赐,愿一罢之。’”帝闻恻然,答其意,止膊物而已。

    处俊资约素,土木形骸,然临事敢言,自秉政,在帝前议论谆谆,必傅经义,凡所规献,得大臣体。

     The answer to protecting and saving marine(海洋) wildlife can start with cutting back on something Americans use every day—plastic drinking straws. Actor Adrien Grenier, best known for playing Vincent Chase in 2015 movie Entourage, has launched a campaign to reduce the amount of single-use plastic usage in this country in order to protect and save marine wildlife and the environment. Plastic drinking straws are among many single-use plastic products contributing to the shocking loss of marine life, but they're a great place to start because they're something Americans are using by the hundreds of millions without any awareness that they're so damaging.

     According to Ecocycle, an international environmental organization, Americans use more than 500 million straws daily, which are enough to fill 127 school buses each day, and they can’t be recycled. They means plastic straws end up in landfills or oceans, where fish and other marine wildlife mistake the small bits for food and swallow them. After seeing a photo of a whale beached on the shore with a belly full of plastic, Grenier felt the inspiration to launch the Lonely Whale Foundation, hoping to inspire and educate others on the challenges facing marine life.

     Along with stopping the use of straws, Grenier hopes to educate consumers on the dangers of other single-use plastic items such as grocery bags and water bottles. While many Americans use these plastic products in their daily life, there are more sustainable alternatives that can help protect the environment. Ecocycle recommends the use of straws made from stainless steel, glass, and even bamboo instead of plastic. You can buy a number of these environmentally friendly straws online and in stores.
