Ecological Homeostasis

Are We Short of Water and Food ??

http://www.lovinghut.com/
Since the vegetarian diet is the most effective solution to global warming, under Supreme Master Ching Hai's guidance, members of The Supreme Master Ching Hai International Association recently opened a chain of Loving Hut vegetarian restaurants around the world, in the United States, Japan, Indonesia, Au Lac and Formosa. These places provide affordable and high-quality vegetarian delicacies to the public, bringing a positive impact on the food and beverage industry...
Meat or vegetables? Independent online (SA)
A recent study has revealed that giving up meat could drastically reduce one's carbon footprint. A diet with meat is responsible for producing in a year (as many) greenhouse gases as driving a mid-sized car for 4,758 km, the Institute for Ecological Economy Research (IOeW) said last week. But the food a vegetarian consumes in (the same period of time) is responsible for generating (gases only) as driving for 2,427km, the IOeW said in a study commissioned by independent consumer protection group Foodwatch...
Vegetarian Shoes And Bags
The term pleather ("plastic leather") is a slang term for synthetic leather made out of plastic, a portmanteau of plastic and leather, the term can be either descriptive, or derogatory, depending upon the user (the derogatory use implies use as a substitute for genuine animal hide leather to cut costs)...

  • Galactic Highway - The Wormhole

    • Wormholes are a valid consequence of Einstein's general relativity view on the universe. A wormhole, in theory, acts as a shortcut or tunnel through space and time. There are several versions on the same theme (i.e. wormholes may link different universes; they may link the two separate locations in the same universe; they may even link black and white holes together), but the physics is similar, wormholes create a link two locations in space-time, bypassing normal three dimensional travel through space. Also, it is theorized, that matter can travel through some wormholes fuelling sci-fi stories like in the film Stargate or Star Trek: Deep Space Nine.

    If wormholes do exist however, it is highly unlikely that you'll find a handy key to open the mouth of a wormhole in your back yard, they are likely to be very elusive and you'll probably need some specialist equipment to travel through them (although this will be virtually impossible).

    Alexander Shatskiy, from the Lebedev Physical Institute in Moscow, has an idea how these wormholes may be observed. For a start, they can be distinguished from black holes, as wormhole mouths do not have an event horizon.

    Secondly, if matter could possibly travel through wormholes, light certainly can, but the light emitted will have a characteristic angular intensity distribution. If we were viewing a wormhole's mouth, we would be witness to a circle, resembling a bubble, with intense light radiating from the inside "rim". Looking toward the center, we would notice the light sharply dim. At the center we would notice no light, but we would see right through the mouth of the wormhole and see stars (from our side of the universe) shining straight through.

  • Stream of Time

    • Plato argued that time is constant - it's life that's the illusion. Galileo shrugged over the philosophy of time and figured out how to plot it on a graph so he could get on with the important physics.

    Albert Einstein said that time is just another dimension, a fourth one to go along with the up-down, side-side, forward-back we move through every day. Our understanding of time, Einstein said, is based on its relationship to our environment.

    Weirdly, the faster you travel, the slower time moves. (Is it truely weird? Not quite!!) The most radical interpretation of his theory: Past, present, and future are merely figments of our imagination, constructs built by our brains so that everything doesn't seem to happen at once.

We found Nemo!

國立海洋生物博物館今年進行大規模的小丑魚繁衍計劃，至今已成功繁殖出第三批的小丑魚，由於繁殖技術不易，海生館已將新生小丑魚與國際間進行交流。

色彩鮮豔的小丑魚因海底總動員裡的「尼莫」而出名，小丑魚不但美麗而可愛，誕生過程更是見證大自然的神奇和無奇不有。

俗名「公子小丑魚」的小丑魚，寶寶剛出生時，全部都是雄性，當能獨自生活時，就會出外尋找一株適合牠的海葵定居。雖然海葵有會分泌毒液的觸手 ，但小丑魚身上也有獨特的黏液 ，所以海葵傷得了別人，卻傷不了牠，反而成了小丑魚的守護神。當然小丑魚也不是白住這裡，有時會幫海葵清理廢物，有時會帶食物給海葵享用免費大餐，牠們是互利共生的好朋友，一同在珊瑚礁中悠遊度日。

一棵海葵會有一群小丑魚定居，而這群小丑魚中，最大的一隻會變性成母魚，與第二大隻小丑魚結為夫婦，配對繁殖下一代。如果不幸這隻雌性小丑魚死亡，第二大的雄性小丑魚即會轉變成雌性，努力接下傳宗接代的棒子。

人工繁殖技術中，必須要確定配對成功的小丑魚後，將這對小丑魚移到適合牠們生存的特殊環境，讓牠們孵化產卵。小丑魚在出生的七天內是存活關鍵期，這時必須培育「藻水」，讓小丑魚幼魚攝取足夠的營養。

在各國水族館中，只有澳洲的水族館繁殖成功；日本有進行繁殖計劃，但沒有成功的報告出現；美國水族館沒有進行小丑魚的繁殖。 由於海生館的小丑魚繁殖技術已成熟，往量化繁殖的計劃實現中，海生館已開始將新生的小丑魚與國際間進行交流，陸續將小丑魚輸出至美國等地，讓台灣的養殖技術在國際間發光。

除此之外，維護全世界海洋生物資源、遏止人為破壞，已成為當今國際社會很重要的議題。在這趨勢下，各海域的觀賞魚類陸續被完全禁止捕撈、或有限制的捕撈。例如歐盟等地區已蘊釀施行禁止販賣野生動物 (含野生觀賞魚類) 之法令。近年來台灣地區因人為濫捕及環境污染，海域生態遭受遇到嚴重破壞，小丑魚數量已經銳減。若能提供人工繁殖的小丑魚給觀賞魚市場，可減少天然海域小丑魚被撈捕的危機。

開發重要海水觀賞魚類的人工繁殖技術勢必激起全球競爭。台灣地理、天候環境很適宜繁衍水產生物。水產種苗產業以及相關的周邊產業已相當發達，極有機會創造另一個台灣水產養殖奇蹟，開創海水觀賞魚類繁養殖之新型產業。
