【題目】面對全球變暖的趨勢,人們應該怎樣應對?至少說出2個應對策略。
【答案】①研究提高能源利用技術和能源利用效率②積極開發(fā)利用新能源,加強國際間的合作 ③增強人們的環(huán)境保護意識;植樹造林,保護好現(xiàn)有的原始森林。(答案合理即可)
【解析】
自工業(yè)革命以來,人類向大氣中排入的二氧化碳等吸熱性強的溫室氣體逐年增加,大氣的溫室效應也隨之增強,已引起全球氣候變暖等一系列嚴重問題,引起了全世界各國的關注。
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。面對全球變暖的趨勢,人類可以這樣做: ①研究提高能源利用技術和能源利用效率②積極開發(fā)利用新能源,加強國際間的合作 ③增強人們的環(huán)境保護意識;植樹造林,保護好現(xiàn)有的原始森林。
