下列是一段关于我国国情的材料:
我国人口占世界人口的22%,而耕地只占世界耕地的7%。从1980年到1996年,粮食产量增长52.9%,但由于人口增长24%,人均占有粮食只增长23%。近几年每年净减少耕地面积在300万至500万亩左右。据有关部门测算,目前受水土流失危害的耕地占耕地总面积的1/3;过去10年沙化的土地占国土面积的15.9%;由于过度采伐,现有森林覆盖面积只占全国面积的13.4%;由于水资源短缺,部分城市缺水现象严重。在全国500个城市中,有300多个城市缺水,其中40多个城市严重缺水。在资源相对不足的情况下,又存在着大量的浪费现象,而且对资源的再生利用又不重视,废钢铁和废有色金属回收利用率只有30%,大大低于经济发达国家60%~80%的水平。
根据材料请回答:
(1)结合上述材料说明历史唯物论关于自然环境是社会存在和发展的必要条件的原理。
(2)结合材料说明历史唯物论关于人口是社会存在和发展的必要条件的原理。
(3)结合(1)(2)说明我国在现代化建设中必须实施什么样的战略。
