    "How to Let Co of the World and Love All the Things Climate Can't Change" is the latest movie from film-maker and climate activist Josh Fox.The movie is the third film in a three-part series about climate change.

    In 2010,Fox's documentary "Gasland" was appointed for the highest award-an Oscar. "Gasland" explored the hotly debated process of removing natural gas from the ground.He examined the subject again in "Gasland Ⅱ".

    Fox was in Washington,D.C.recently to present his third film.He was arrested during a protest against a new fuel pipeline.In the film,Fox says pollution from fossil fuels must be reduced.Without limits,there will be more extreme weather,like severe storms and dry weather,rising sea levels,causing shortages of food and water, "When you really encounter that head on,it causes an in-credible crisis."

    In the new film,Fox travels through a sunless forest in the Amazon with local activists to measure oil spills.He goes to a village in Ecuador to learn how people there stopped a pipeline from being built.He joins young people in Australia to stop boats from entering the port of Newcastle.

    "You should probably know the downside of what we're about to do.This is the short list: drowning,being arrested: being run over by boats,drifting away in currents out into the Pacific Ocean,cultural disrespect,big waves."

    Also in the film,Fox talks to Ella Zhou,an energy expert.She explained the importance of what she calls "moral imagination"."I think that it forces us to get out of our box of thinking about,for instance,what is being successful.It allows us to have a moral value about what you want as a person.What do you want to do for the world and for yourself?"

                                                                                       食虫植物开花
        ①曾经无数次想象吃荤的植物究竟开出怎么样的花，大腹便便、或是油头粉面、又或是张牙舞爪？近日，华南植物园温室群景区内的“白颈”、“朱思迪”等多个品种的瓶子草已进入花期。瞧！花儿虽然没有它叶子的那份趾高气扬，但是也绝不低调，花茎高高挺出，有的甚至比叶子高出许多，柔弱的花茎支撑着硕大的花朵显得有些吃力。紫色，粉红的花朵明媚中带着几分羞涩，恰是那一低头的温柔，吸引了无数关注的目光。 
        ②瓶子草是奇特的食虫植物，它利用叶子来捕捉和消化蚂蚁、苍蝇、蚊子等昆虫。其瓶状叶是有效的昆虫陷阱，瓶状叶外部色彩鲜艳，内壁能分泌消化液，与瓶内贮藏的雨水相混，起到溺死并消化昆虫的作用。瓶状叶的开口处常分泌香甜的蜜汁，引诱昆虫前来采吃，一旦受骗的昆虫爬进内壁，滑落到瓶内的消化液里，将受到内壁的倒刺毛挡住去路，最终溺死其中无法逃出生天。昆虫的尸体在瓶子草消化酶的作用下，变为营养物质氨基酸被瓶壁吸收。
        ③吃饱喝足的瓶子草在每年的4-5月开出了美丽的花朵。花单生茎顶，两性，花朵较大，呈紫色或粉红色。细心的你一定会发现花朵具有复杂而精密的构造。
        ④瓶子草最主要的授粉者是蜜蜂，蜜蜂要采蜜的时候，由于花朵的构造，它们必须先经过其中一个柱头，才能进入倒伞状的空腔部分。在空腔内，它们不免会沾到一堆来自花药或者掉落的花粉。离开的时候，也由于花朵的构造，蜜蜂得从其中一个盖状的花瓣出去，这种方式可以避免蜜蜂经过柱头造成自花授粉。正是瓶子草的这种异花授粉也就决定了它的不简单。 
        ⑤当然聪明的瓶子草不会对所有造访的昆虫都格杀勿论，为了避免授粉的有益昆虫掉进“瓶”内被误食，它的花茎往往高出叶子很多。瓶子草设下美丽的陷阱，只吃它们“相中”的食物，而对帮助它们传粉的昆虫，则温柔地网开一面。
