Oceans Claim our Attention
We’ve already pushed the world oceans close to -and in some cases, past-their natural limits, according to a recently released report on the state of our oceans by the World Watch Institute.
The increasing number of citizen groups, business and governments taking an active interest in slowing down the destruction and pollution of the ocean is encouraging, says senior researcher and author Anne platt Mcginn, citing a host of efforts already under way: 1. Unilever, which controls 20 percent of the whitefish market in Europe and US, has agreed to buy only fish caught and produced in an environmentally sustainable manner. 2. Volunteers in the philippines, Thailand, India, and Ecuador are replanting mangrove areas to repair earlier damage from shrimp farming. 3. In northern Sulawesia, citizens have cleared coral reefs of harmful invasive species. 4. The United States and Canada have each banned oil drilling on large portions of their continental shelves.
0n the downside, Safeguarding the Health of oceans says that seven out of ten commercial fish species are fully or overexploited and even worse, many of their spawning grounds have been cleared to make room for shrimp ponds, golf courses and beach resorts. Habitat degradation, resulting from development, agricultural run off, sewage pollution and destructive fishing practices has led to a tripling in the number of poisonous algal species identified by scientists, increasing fish kills, beach closures, and economic losses.
The impact on the economy is significant. people obtain an average of 16 percent of their animal protein from fish, and people in developing countries are extremely dependent on reef fisheries for both food and income. Tourism accounts for a large piece of coastlines and medicines are being found in reef ecosystems every day. Even toothpaste and ice cream depend on the gel-forming properties of brown algae.
The problems facing the oceans are legion: the marine conversation community is fragmented, bans on destructive activities are routinely ignored, too many regulatory organizations have a development-first mindset and enforcement and oversight are ineffective, if not altogether lacking. oceans need to be protected locally, nationally, and internationally, according to McGinn. Right now, the United Nations General Assembly spends just one day a year covering issues that affect more than half of the planet. The report suggests that a tax of one tenth of one percent on industrial and recreational ocean activities would generate $500 million a year, more than five times and the annual budgets the International Maritime organization and the Fisheries Department of the UN Food and Agriculture organization.
However, the most productive areas of the ocean are under national jurisdiction and 80 percent of oceanic pollution originates on land. This means that addressing global marine issues requires strong national and local policies. problems remain far from resolved.

A. The growth of mangroves kept shrimps from reproducing.

參考答案：
1. A
第二段有這樣一段話：---buy only fish caught and produced in an environmentally sustainable manner.即只購買那些環(huán)境上 sustainable 的地區(qū)捕獲和生產(chǎn)的魚類。據(jù)此可以推斷，此處的sustainable 指可持續(xù)發(fā)展的。與之相近的詞是maintainable
2. B
第二段告訴我們菲律賓的紅樹生長與蝦養(yǎng)殖的關(guān)系。文中說：志愿者重新種植紅樹，以修復(fù)早期蝦養(yǎng)殖引起的破壞�？梢�，蝦養(yǎng)殖破壞了紅樹的生長。
3. D
從第三段我們可以看出：70%的商業(yè)魚種被過分捕撈;許多魚類的產(chǎn)卵地被清理掉，以給蝦池滕出地方;破壞性捕撈還使經(jīng)濟損失進一步增加。所以，A，B，C都是破壞性捕撈行為的結(jié)果。通過全文，我們可以看到，只有一些國家采取了措施禁止破壞性捕撈，并不是每個國家都采取了措施。
4. B
文章的第五段指出：那些對環(huán)境問題持有發(fā)展優(yōu)先態(tài)度的組織忽略了禁止破壞性捕撈這一規(guī)定。由此可以推斷，他們將無視環(huán)境保護問題，把海洋資源的開發(fā)放在第一位。
5. A
這篇文章實際上要通過一系列海洋破壞引起的后果給人們敲響環(huán)境保護的警鐘。 文章在談到環(huán)境保護的`問題時稱：這一問題還有待解決。由于海洋的多數(shù)富饒區(qū)都處在各個國家的管轄內(nèi)，并且80%的海洋污染來源于陸地，所以我們可以由此推斷：國際級的環(huán)境問題仍然很難解決。B 在捕魚和觀光中征稅還是一個建議，文章沒有告訴我們是否有國家會采納這一建議。C 聯(lián)合國某機構(gòu)一年只花一天時間討論這一問題，可見他們對海洋保護不夠重視，文章也沒有告訴我們聯(lián)合國是否已經(jīng)采取了有力的措施來保護海洋。D 從文章展示給我們的世界各國的海洋保護的現(xiàn)狀來看，海洋問題并沒有引起人們足夠的重視。
