我們把地球當敵人,9 項居住指標已超標 4 項

文章 laraliang » 週四 19 3月, 2015 18:04

「地球一直是我們的好朋友,但我們卻把它當敵人對待。」

今年年初全球環境永續發展的專家 Johan Rockström 表示:

「現在的地球氣候變化太快、樹砍太多、生物多樣化大幅下降,已經有 4 項指標超出了地球的負荷。」

大家看過穹頂之下

人類對環境的傷害終將反撲!!!

現在還不是末日,從小地方做起吧

一起守護地球!!!

Dear Chan Sir,
I think the video has lots of inaccuracies and errors, but I do think air pollution is a big problem to Chinese urban residents.

I'm not that sure if people's general health is irrelevant to the pollutants in the air, as some experts say, but I do feel irritated throat each time I visit Guang Zhou.

Air pollution is not the big problem in China especially the urban area.
what is the reasons?

We shouldn't believe our eyes and nose.

Yes we may be destroying our environment but no in such a degree that we will soon kill our planet. Earth is still in good shape. It;s a pity that mass media always exaggerates in order to attract eyeballs.

Take Peking for example, the so called "smog" may not all entirely originate from air pollution. Actually quite a part of "smog" comes from water vapor in air and tiny sand particles blowing in from northern deserts. They are part of the nature.

Of course pollution plays a part, but not as a terrible part as some movie/media said.

Goto Beijing and stay there for two to three weeks. You may change your view. Before that, please do not comments! I was there in the past couple of years for a couple of weeks. I would not go again unless it is absolutely necessary. :roll: :roll: :roll:

While dust storms can intensify smog, a dust storm on its own can never cause smog. We have a lot of Saharan dust storms in northern Africa but no smog. However, when the Saharan dust storms reach cities in southern Europe, they can make things worse because they provide surfaces for the certain pollutants to be decompose by sunlight into something more nasty.

Smog is basically formed when local air pollutants cannot be disbursed to the upper atmosphere because of an inversion layer. Pollutants combinded with water to form a mists of harmful solutions which affect our respiratory system. Such harmful effect is much more serious than the effect of dust storms or fog (water droplets only) alone.

I had been to Northern Sahara ( Tunisia to be precise) for a 10 days trip few years ago. The transparency of sky was very poor. It rather looks like "smog" in Peking.

Tunisia has not much pollution but they still have rather heavy "smog" or something very like "smog". So "smog" may not necessarily originated from air pollution.

The same happened in XingLong. The first time when I was there I saw very heavy "smog". The transparency of air was so poor that scenery few km away just vanished. But at night I saw one of the most wonderful starry sky ever.

I haven't been to Beijing but I'm not sure whether we should believe to the tv news and the offical meterological reports as we have seen so many photos and videos from the news.
:roll:

Anyway, it is still sure that air pollution and global climatical change does happening on our planet ,and they are caused by human activities although there are some wrong concepts between duststorm and smog have made by the movie creator.

我唔係好識地理,但打死都唔應同人類破壞自然環境問題唔嚴重,、

片中嘅沙塵同毒霧嘅分别都唔係重點啫,都成日聽香港D空氣質素同風
向有關,d煙霞咪由大陸吹黎。

如果個個咁應為,大陸D工廠咪有籍囗反對減廢氣排放,
香港d煙霞咪愈黎愈嚴重?受害嘅都係你地班觀星友。 :shock: :? :?

of course not
香港天文台都係傳媒之一,睇下信邊個傳媒啫,大陸空氣污染
問題向來都唔係咩秘密㗎啦。

莫非呢度有好多中石化嘅股民。 :roll:
