据英国《卫报》网站报道，昆虫的灭绝速度是哺乳动物、鸟类和爬行动物灭绝速度的8倍，昆虫的数目正在以每年2.5%的速度减少。如果不采取保护措施，也许昆虫会在100年内彻底灭绝，从而导致整个生态系统的崩溃！植物会因为失去授粉昆虫而灭绝，以昆虫为食的鸟类、蝙蝠、蛙类等动物将大量饿死，而以这些动物为食的大型食肉动物也势必随之减少。

与此同时，虽然目前环境让多种昆虫数量锐减，但这种气候温暖、二氧化碳含量较高的环境却有利于蚊子、蠓（Ceratopogouidae）、蚋（Simuliidae）等吸血昆虫形成更多的新品种。因为吸血昆虫喜欢温暖、高二氧化碳的环境，在环境适宜、食物充足的情况下，基因变异的吸血昆虫容易存活下去并形成新物种。这些新物种吸血昆虫可能会传播更多疾病，威胁人畜安全。

昆虫已在地球生存数亿年，但要让它们灭绝只需百年。人类在自身发展的同时，也应顾及其他生物的生存，否则到头来承担后果的还是人类自己。
