2020 媽盟直播室 Episode 17 - 植樹減碳的效益被高估!
根據一項對樹木生長和死亡率調查顯示,亞馬遜熱帶森林的吸收速度,自1990年代以來,二氧化碳的排放量已經放緩,估計到2035年,將從吸收碳轉為碳排放的大宗!原因除了原始林不僅會老化死亡之外,還有野火、砍伐、人為開發等破壞。因此要具體減碳,光靠植樹,是過於樂觀的想法。

(影片重點)
※有些國家在去年COP25提出希望利用植樹來做為減碳的一個目標或額度,但是用植樹來減碳是否有效?
※平地造林的效果被誇張?目前看來,因為大部分造林都是同一種樹種,長不高且不適合造林,不利於生態的多樣性。
※樹木吸收二氧化碳的實際情況到底是如何?樹木雖然能吸收二氧化碳,它也有代謝與排放,而落葉腐化後又將回復成二氧化碳。
※人類的行為和氣候的變化導致二氧化碳濃度變高,使得非洲及亞馬遜幾百處原始林吸收碳的能力在慢慢下降,而亞馬遜由於濫伐開墾,樹木死亡比非洲來得更快。

樹木吸收二氧化碳 在 MyGoNews不動產網路新聞粉絲團 Facebook 的精選貼文
📢🆕中華工程:「 陶朱隱園 」售價,比高端豪宅多3倍也合理🏢📈
🔶#陶朱隱園 獲CNN評選為全球九大城市新地標,獨特順時針向上旋轉的藝術外觀,傳承陶朱公公益精神,全棟廣植樹木吸收二氧化碳。
🔶由於其珍稀絕之特點,國際房產代銷業標榜該案「不是唯一 不收藏」,陶朱隱園既為全球唯一,絕對值得當成藝術品收藏。中華工程表示,陶朱隱園的售價若以其藝術價值及結構壽命而言,依外界所傳為信義區高端住宅市場行情3倍以上亦相對合理。

樹木吸收二氧化碳 在 譚凱邦 Roy Tam Facebook 的精選貼文
明明可以用的地還有
明明要從需求落手,又不去做
一定要開發郊野公園,是何居心?!
.
一寸都不能少!!
【環保團體聯合聲明】
【Joint Statement from Green Groups】
反對開發郊野公園 不接受「可加可減」
郊野公園具重要旅遊康樂及規劃功能 港人重要綠色寶庫
應先善用棕土、軍營及閒置土地
Objection to Developing Country Parks and the Adjustment Mechanism
Make Use of Brownfield Sites, Military Camps and Spare Land
行政長官梁振英向傳媒公開表示,已指示政府部門就發展郊野公園作研究。環保團體對此感到十分憤怒,因為社會有眾多聲音明確反對開發郊野公園,政府當局仍然一意孤行,更為此目的投放資源作具體行動,是蓄意與社會製造矛盾。
.
香港仍有不少可作發展的土地,過去房屋問題只源自「分配不均」。政府多年來逃避檢討「丁屋政策」(為丁屋預留土地)、未有動用閒置的軍營、未有以「棕土優先」發展等,為導致目前情況的主要原因。政府亦沒有正視大量住宅單位空置及私樓單位成為投資工具的問題,是政府的政策出錯,卻以缺地作掩飾。明明有其他可行及有共識的可用土地,政府仍以老人家及公屋輪候冊上的人為人質,提出發展郊野公園,是絕不可接受。
.
郊野公園是香港重要的特色,亦是重要綠色寶庫,除包含保護珍貴生態的環境價值,亦有旅遊(香港的郊野公園世界聞名)、社會(供大眾休憩)、規劃(限制城市過度擴張)等重要功能。郊野公園亦是重要集水區,讓足夠雨水流入周邊的水塘,提供港人生命之源。郊野公園有大量樹木,吸收二氧化碳,抵銷部份因燃燒化石燃料產生的溫室氣體,紓緩全球暖化。郊野公園亦有無以彌補的珍貴地質地貌。
.
梁振英指可選取「生態價值較低」的地帶發展,我們並不同意。郊野公園的一草一木、花鳥蟲魚皆是生命,她們亦有自身存在的意義與價值,而生態價值亦沒有百份百客觀標準衡量。梁振英提出郊野公園「可加可減」機制,更是保育的「語言偽術」,。現存的每一片郊野公園的地理位置、地勢、環境及生態本來就獨一無二,不應被任何藉口取締,以另一處新郊野公園「面積」作交換是誤人耳目。
.
梁振英在未有善用棕土、軍營及閒置土地之前,就提倡開發郊野公園邊陲,是規劃目標錯誤。房屋問題亦不能單靠盲目覓地處理,亦需要同時透過人口政策,控制房屋需求來解決。大自然一旦遭破壞將無法復原,絕不應發展香港人引以為傲的郊野公園。

The Chief Executive Mr. CY Leung told the media that he has instructed relevant departments to conduct a study on developing country parks. Green Groups are furious and strongly opposed to this, as the public has already voiced opposition to the development of country parks. However, the government still insists on doing so and, furthermore, devotes more resources to this, deliberately leading to conflict within our community.
.
In fact, there is still a lot of land available for development in Hong Kong. The housing shortage problem has originated from “Uneven Distribution”. Over the years, the government has avoided reviewing the “Small House Policy” (land designated for New Territories Exempted Houses), unused Military Camps and Brownfield sites. These are the main reasons for the present situation. Moreover, the government has failed to address the problem of vacant housing units and private flats used for investment and speculation purposes, falsely presenting the situation as a “lack of land”. As there are other land resource options, it is totally unacceptable for the government to use the welfare of the elderly as an excuse for developing country parks.
.
Country Parks are important features and treasures in Hong Kong. Apart from the environmental value of preserving our precious ecology, they are also well-known for eco-tourism, community enjoyment (for public recreation) and even have a role to play in urban planning (for preventing over-expansion of the urban areas). Country parks are also important water catchment areas, which allow rainwater to flow into surrounding reservoirs. Furthermore, trees in country parks can absorb carbon dioxide and offset some of the greenhouse gas emissions from burning fossil fuels, which relieves global warming.
.
Mr. CY Leung pointed out that low ecological parts of country parks can be developed. We totally disagree with his claims. All the plants, flowers and birds in the country parks have their own meaning and value to the natural environment. Ecological value cannot be measured in objective criteria. He further suggested the “Adjustment Mechanism” in Country Parks, which we consider to be “weasel words” designed to mislead the public about conservation. The geographical location, the terrain, environment and the ecology of each existing country park are unique and should not be replaced by any excuses. The exchange of another “new” country park area is totally a mistake.
.
Mr. CY Leung hasn’t made good use of brownfield sites, military campsites or spare land before advocating the development of country park borders. Hong Kong’s housing problem could also be solved not just by finding land but also by controlling housing demand through a population policy. Once the natural environment is destroyed, it cannot be restored to what it was before. Therefore, the government should not develop our country parks, which are the pride of Hong Kong people.
