The area of desert in the world is growing every year. Many parts of the world which once had large populations and produced plenty of crops, have become deserts. Dunhuang in China, deep in the heart of the Gebi Desert, was once a great city.

Cattle are one cause of the problem. In good years, famers increase the numbers of their cattle. Then one year, the rains fail to come. The farmers do not want to kill any of their cattle, so the cattle eat ail the grass and anything that grows on poorer land. If this continues for several years, the grass never grows again and the land becomes a desert. One suggested answer is for farmers to limit the numbers of their cattle.

Another problem is that good soil is gradually lost. When trees are cut down, there is nothing to hold the soil in place on the hillside. So when if rains, the soil is washed down the hills and into the rivers. Strong winds can also blow away the valuable soil that lies on the top of the fields.

目前,日趋严重的毒品问题已成为全球性的灾难。毒品的泛滥直接危害人民的身心健康,并给经济发展和社会进步带来巨大的威胁。 据联合国的统计表明,全世界每年毒品交易额达5000亿美元以上,毒品蔓延的范围已扩展到五大洲的200多个国家和地区,而且全世界吸食各种毒品的人数已高达2亿多,其中17~35周岁的青壮年占78%。

毒品已成现今困扰社会生活最大的祸患,多少人因这个仅次于军火而高于石油的世界第二大宗买卖失去了学习的机会、工作的能力,出卖了自己的良心,背弃了家人与朋友,甚至失去了活在世上的意义,更为严重的是有人就因这小小的药丸献上了年轻且无价的生命!请人们仔细地想想,你觉得这样值吗?有很多因吸毒或贩卖毒品的人们,就用他们一个又一个的曲折而惨痛的经历告诉我们,毒品的危害是多么的巨大啊!!

“毒品”,两个再简单不过的字眼,可出现的频率却非常之高,在报纸上、宣传栏里、书本中……但是它到底是什么,为什么不仅可以对吸毒者个人造成无法形容的伤害,而且还带给吸毒者家庭乃至社会非常巨大的伤痛与影响呢?

其实毒品并非是“毒性药品”的简称。它是指出于非医疗目的而反复连续使用能够产生依赖性(即成瘾性)的药品。从自然属性来讲,这类物质在严格管理条件下合理使用具有临床治疗价值,也就是说,在正常使用下,它并非毒品,而是药品。不过,从社会属性来讲,如果为非正常需要而强迫性觅求,从而这类物质失去了药品的本性,这时的药品就成为了毒品。因此毒品是一个相对的概念。当然也有些物质成瘾性大,早已淘汰出药品范围,只视为毒品,例如海洛因。

吸毒——这一丑恶现象乘着我国改革开放之机,肆无忌惮闯了进来,带来的危害真是数也数不清!主要对人体与身心的危害在于毒品作用于人体,使其体能产生改变,形成在药物作用下的新的平衡状态。一旦停掉药物,生理功能就会发生紊乱,出现戒断反应,使人感到痛苦万分。许多吸毒者在没有经济来源购毒、吸毒的情况下,或死于严重的身体戒断反应引起的各种病发症,或由于痛苦难忍而自杀身亡。所以这种戒断反应的痛苦,反过来又促使吸毒者为避免这种痛苦而千方百计地维持吸毒状态。也有很多人忍受不了这种强烈的痛苦而不断加大剂量,使吸毒者终日离不开毒品。而毒品进入人体后又作用于人的神经系统,出现精神依赖性,并导致幻觉和思维障碍等一系列的精神障碍。使吸毒者出现一种渴求用药的强烈欲望,驱使吸毒者不顾一切地寻求和使用毒品,甚至为吸毒而丧失人性。吸毒不仅对人体与身心有一定的危害作用,还带给社会与家庭不少的伤痛。家庭中一旦出现了吸毒者,家便不成家了。吸毒者在自我毁灭的同时,也破害自己的家庭,使家庭陷入经济破产、亲属离散、甚至家破人亡的困难境地!并且对社会生产力有巨大的破坏性,还扰乱社会治安,带给人们巨大的威胁,毒品活动造成环境恶化,并逐年缩小了人类的生存空间。

毒品带给人类的只会是毁灭。旧中国,我们曾受鸦片的泛滥,而被称为“东亚病夫”,使民穷财尽、国势险危。吸毒于国、于民、于己有百害而无一利!毒品摧毁的不但是人的肉体,也是人的意志。我希望人们要积极宣传毒品的危害,自觉地与吸毒、贩毒等不法行为作斗争,珍爱生命,终身远离毒品、拒绝毒品!

有些路,永远不能走;有的错,永远都不能犯!

青少年如何防止吸毒 (1)接受毒品基本知识和禁毒法律法规教育,了解毒品的危害,懂得“吸毒一口,掉入虎口”的道理;
(2) 树立正确的人生观,不盲目追求享受,寻求刺激,赶时髦;
(3) 不听信毒品能治病,毒品能解脱烦恼和痛苦,毒品能给人带来快乐等各种花言巧语;
(4) 不结交有吸毒、贩毒行为的人。如发现亲朋好友中有吸、贩毒行为的人,一定要劝阻,二要远离,三要报告公安机关;
(5) 不进歌舞厅,决不吸食摇头丸、K粉等兴奋剂;
(6) 即使自己在不知情的情况下,被引诱、欺骗吸毒一次,也要珍惜自己的生命,不再吸第二次,更不要吸第三次。

而与毒品密切相关的是艾滋病,艾滋病是一种病死率极高的严重传染病,目前还没有治愈的药物和方法,但可以预防。艾滋病威胁着每一个人和每一个家庭,预防艾滋病是全社会的责任。艾滋病在全世界,特别是在发展中国家迅速蔓延。我国艾滋病流行已进入快速增长期。 如不能及时、有效地控制艾滋病的流行,将会对国家的社会、经济发展造成严重影响。 建立政府领导、多部门合作和全社会共同参与的艾滋病预防与控制体系,形成有利于艾滋病防治的社会环境是控制艾滋病流行的重要成功经验。
每个人都有权且必须懂得预防艾滋病的基本知识,避免危险行为,加强自我保护。向青少年宣传预防艾滋病、性病的知识,开展学校性教育,保护青少年免受艾滋病、性病的危害,是每个家庭、每个学校、每个社区和全社会的共同责任。
远离毒品,预防艾滋病。我希望不仅仅是个口号,更是我们付诸行动的强大信念。
