初中生以保護(hù)鯨魚為主題的英語(yǔ)作文
Marine environment is one in water, seawater tolerance hydrolyzate and suspended solids, seabed sediment and marine organisms, including complex systems. Ocean rich biological resources, mineral resources, chemical resources and power resources is an indispensable resource treasure house of human beings, with human survival and development of the relationship very close.
The main objective of the current marine conservation is to protect the living marine resources, so as not to failure, in order for human sustainable use. In particular, give priority to protect those valuable and critically endangered marine life. According to the UN for investigation, due to overfishing, accidental capture and killing of non-target to allow hunting of marine, coastal shoreline construction, mangrove deforestation, widespread marine pollution, at least the world's 25 most valuable fishery resources depleted, whales, sea turtles, manatees and many other marine animals face extinction risk. Is expected that with the expansion of the scale of ocean development,
Marine living resources are likely to cause more damage.
The task of the first marine protected right to stop over-exploitation of living marine resources and secondly to protect the habitat of marine life or habitat, in particular, their migration, spawning, foraging, avoiding predators coast, tidal flats, estuaries, coral reefs, it is necessary to prevent the heavy metals, pesticides, oil, organic and easy to produce nutrients such as eutrophication of marine pollution. Preservation of the marine living resources of the natural regeneration capacity and water purification capacity, preservation of the marine ecological balance, to ensure sustainable human development and utilization of the oceans.
海洋環(huán)境是一種在水、海水、寬容和懸浮固體物水解液海洋底質(zhì)和海洋生物,包括復(fù)雜的系統(tǒng)。海洋豐富的生物資源、礦產(chǎn)資源、化工資源和電力資源是一個(gè)不可或缺的資源寶庫(kù)人類,與人類的生存和發(fā)展的關(guān)系非常密切。
目前的首要目標(biāo)是保護(hù)海洋保護(hù)海洋資源,使生活不失敗,為了人類的持續(xù)使用。特別是,優(yōu)先保護(hù)那些有價(jià)值的、嚴(yán)重瀕臨滅絕的海洋生物。根據(jù)聯(lián)合國(guó)調(diào)查,由于過(guò)度捕撈,意外捕獲和殺害,對(duì)非靶標(biāo)生物的允許打獵、沿海岸線建設(shè)海洋、紅樹林森林砍伐,廣泛的海洋污染,至少世界上的25個(gè)最有價(jià)值的漁業(yè)資源枯竭、鯨魚、海龜、海牛和許多其它海洋動(dòng)物面臨滅絕的危險(xiǎn)。預(yù)計(jì),隨著規(guī)模的擴(kuò)大海洋開發(fā),
