More than 8 million tonnes of plastic end up in the ocean each year. By the middle of the century, there will be more plastic in the sea than fish. The plastic trash of modern life – bottles, bags, packaging, and more – is broken down over many decades into tiny fragments that closely resemble the natural food of birds, fish and turtles.　Sea creatures are starving to death because their stomachs are so full of plastic.　Could we also be at risk? Scientists are now finding alarming evidence that plastic is in our seafood. And with it come toxic chemicals.

Facebook的困局 (上集) 

社交媒體Facebook成立近14年，用戶數量超過20億，成為最多人使用的社交平台。但隨着用戶不斷增多，影響力亦越來越大。2011年「阿拉伯之春」革命浪潮席捲埃及，外界形容這次革命為「Facebook革命」，反政府團體透過Facebook號召民眾，成功推翻極權政府。但亦有組織被指利用Facebook平台發佈假消息，散播仇恨情緒，煽動民眾作出激烈行為，從而分化社會。另外，輿論亦指Facebook收集大量用戶的個人資料，不但未有妥善處理，更涉嫌用以圖利。面對種種質疑，創辦人朱克伯格如何拆解？

The promise of Facebook was to create a more open and connected world. But from the company’s failure to protect millions of users’ data, to the proliferation of “fake news” and disinformation in the U.S. and across the world, mounting crises have raised the question: How has Facebook’s historic success as a social network brought about real-world harm? The documentary shows a dozen of original interviews and rare footage, investigates a series of warnings to Facebook as the company grew from Mark Zuckerberg’s Harvard dorm room to a global empire.

犀牛被列為瀕危物種，多年來，獵殺犀牛的情況從未間斷，而且過程相當殘忍。去年，中國放寬犀牛角買賣禁令，進一步令情況惡化。犀牛角在亞洲尤其受歡迎，有人將犀牛角製作成首飾，亦有人認為進食犀牛角可以醫治癌症。製作團隊獨家採訪前線保護犀牛的巡警，又假扮買家到東南亞購買犀牛角製成品，了解非法販賣犀牛角的運作情況。

In South Africa, poachers kill three rhinos every day. Fueled by the demand for rhino horn in Southeast Asia, where it’s widely believed to have medicinal powers, poaching could see South Africa’s rhino population disappear in just a decade.

尼日利亞是非州最大能源供應國，但過半尼日利亞人沒有電力供應。當地政府一直缺乏有效措施，提高電力輸出。激進組織通過摧毁天燃氣管和電力設施表達他們的不滿；另一方面，市民就冒着生命危險偷電，而電力公司職員上門收取電費時，又往往遇上居民暴力對待。缺電已成為該國各種問題的根源。

危險的連線

每年全球有800萬至1000萬噸塑膠垃圾被倒入大海，這些塑膠會被分解成微塑膠，黏附在海洋生物上。專家指，我們每吃一客青口，便同時吞進900粒微塑膠。塑膠垃圾不但影響人體健康，更可能引發海洋生態災難。日常生活，我們似乎離不開塑膠，這種廉價、方便的物料是否就無可替代?改用瓦通紙、樹葉又如何?另外，有生物學家正研究用昆蟲消滅塑膠。是否可行?

In the year 2050 there will probably be about 10 billion people on earth. But already one billion people are suffering from hunger. Can we feed 10 billion people at all, or are we threatened by wars over food? Our meat consumption has quadrupled in the last 50 years. But it is animal husbandry that poses a threat to food security. Because in order to get a kilo of meat, the animal needs an X-fold of feed, which in turn is missing in the human food chain. How can we prevent future food shortages? Will we only get enough food in the future thanks to insects, algae and astronaut food?
