鼓勵(lì)人們保護(hù)野生動(dòng)物在過去幾十年里,我們已經(jīng)認(rèn)識(shí)到社區(qū)積極管理其周圍的自然資源對(duì)改善經(jīng)濟(jì)和社會(huì)福利是多么重要。我們今天的工作反映了這一基本現(xiàn)實(shí)。我們?cè)诓煌纳鐓^(qū)開展工作,并根據(jù)特定地區(qū)的具體需求和利益調(diào)整工作,同時(shí)考慮到當(dāng)?shù)孛媾R的特殊保護(hù)的挑戰(zhàn)。關(guān)閉亞洲象牙市場(chǎng)非法獵殺大象獲取象牙破壞了全球動(dòng)物數(shù)量。據(jù)估計(jì),每年有近2萬頭大象被獵殺,主要是為了獲取象牙?？傮w而言,我們看到東亞和東南亞市場(chǎng)的需求在增長(zhǎng),其中中國(guó)、新加坡和泰國(guó)的需求最大。我們正在努力關(guān)閉泰國(guó)的非法市場(chǎng),并幫助結(jié)束中國(guó)的合法象牙貿(mào)易。詞海拾貝①missionn.使命;任務(wù)②poachv.
