【題目】面對(duì)全球變暖的趨勢(shì),人們應(yīng)該怎樣應(yīng)對(duì)?至少說(shuō)出2個(gè)應(yīng)對(duì)策略。

【答案】①研究提高能源利用技術(shù)和能源利用效率②積極開(kāi)發(fā)利用新能源，加強(qiáng)國(guó)際間的合作 ③增強(qiáng)人們的環(huán)境保護(hù)意識(shí)；植樹(shù)造林，保護(hù)好現(xiàn)有的原始森林。（答案合理即可）

【解析】

自工業(yè)革命以來(lái)，人類向大氣中排入的二氧化碳等吸熱性強(qiáng)的溫室氣體逐年增加，大氣的溫室效應(yīng)也隨之增強(qiáng)，已引起全球氣候變暖等一系列嚴(yán)重問(wèn)題，引起了全世界各國(guó)的關(guān)注。

全球氣候變暖的原因有兩方面：大量燃燒煤炭、天然氣等產(chǎn)生大量溫室氣體；肆意砍伐原始森林，使得吸收二氧化碳的能力下降。面對(duì)全球變暖的趨勢(shì)，人類可以這樣做： ①研究提高能源利用技術(shù)和能源利用效率②積極開(kāi)發(fā)利用新能源，加強(qiáng)國(guó)際間的合作 ③增強(qiáng)人們的環(huán)境保護(hù)意識(shí)；植樹(shù)造林，保護(hù)好現(xiàn)有的原始森林。
