保护野生动物是人人有责的!按照1992年的《生物多样性公约》的定义,生物多样性是指“所有来源的活的生物体中的变异性,这些来源包括陆地、海洋和其他水生生态系统及其所构成的生态综合体;这包括物种内、物种之间和生态系统的多样性.”通俗点说,生物多样性就是地球上的花草鸟兽及其与环境之间产生的联系.更直白点说,生物多样性就是人类衣食住行的根本来源.
2006年,关于生物多样性的研究被《科学》杂志评为当年的十大科学进展.近期,美国科学家乔纳森·福利的小组在为全球环境设置临界点,其中生物多样性的丧失,以每年每百万物种中的灭绝物种数计,临界值应为10,可怕的是当前值已经大于100,相比工业化前的0.1.0,增长了百至千倍.由此看来,现实是残酷的.生物多样性造就了地球的生机勃勃,同样也让我们人类可以赖以生存.可现在,生物多样性的丧失速度大大超过了可以容忍的限度.不过令人欣慰的是,在全球变暖、大气污染成为现在流行资讯的同时,尚有一部分人关注着生物多样性的变化给地球或者人类生存带来的影响.
作为社会新生力量的当代大学生,在生物多样性目前严峻的形势和不被广泛关注的环境下,倍感身上的责任与焦虑之情.所以,值此“2010年国际生物多样性日”将近之际,我们发出此倡议,让我们一起来为保护生物多样性做一份贡献.
首先,我们希望国家能够为生物多样性保护研究投入更多的经费.分子水平的研究虽然不可缺少,但我们也需要更多的去了解我们身边实实在在活生生的伙伴.它们的喜好,它们的饮食起居,它们的生活环境;我们人类活动对它们造成了多少影响;而不是说我们分子技术有多高,把它们的基因保存下来,以后我们可以复制出另一个生物多样性陪伴我们生活.冷静想想,会让我们去复制吗?当我们认识到自己贪婪的欲望无法满足的时候,已然将地球糟蹋得不成样子的时候,我们想到要恢复重现的时候,还会有时间给我们这个机会吗?美国学者比尔·麦吉本坚信,要停止地球毁灭进程,必须停止发展经济.这个观点以后会被证明或证伪,但我们无法接受这么极端的观点.我们认为,在通往国强民富的道路上,我们可以做好对生物多样性的保护.其一,科学家需要经费.我们需要像珍妮·古道尔那样与猩猩为伴的人.但在这个物质现实的社会中,人们会担忧自己的生活和家庭.我们推崇精神高尚的人,但并不是每个人都可以做到精神高尚,甚至精神高尚的人的结果并不理想.国家应该给那些喜好大自然,热爱从事宏观生物学研究的学者提供保障,而不是让他们失去希望.其二,保护区需要经费.现在的保护区有四个特点:太少,太小,太孤立,太容易受干扰.这样最多能够支持地球上很小一部分生物多样性.要将生物多样性这个大保护区和人类发展融合起来,政府和科学家还要继续沟通,继续商榷.我们希望国家在发表讲话声明,颁布政策法规的同时,可以落到实处,予以积极者支持,予以消极者惩罚.
随着美国的西部大开发,大片森林、草原被毁。美国人几乎砍光了从大西洋畔一直到大平原区的无际的森林,使土地裸露,失去植被保护,种下了祸根。让西部不再美丽,变得很荒凉~寂寞,让我们一起携手保护我们的家园,不要让这样的悲剧再次上演!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!...

保护生物多样性的倡议书
生物的多样性是人类一切社会活动的物质基础,没有生物,特别是植物,我们就无法生存。但是,随着人类生产力的发展和科学技术的进步,生物资源却遭到了过度的开发和利用。
现在,我们正面临着很多严重的生态问题:
在许多地方,不但生物资源已经陷入了枯竭的境地,而且野生动物赖以生存的栖息地的环境也在不断恶化,其面积不断减小;大量的原始森林遭到了过度地砍伐;草场退化;...

生物的多样性是人类一切社会活动的物质基础,没有生物,特别是植物,我们就无法生存。但是,随着人类生产力的发展和科学技术的进步,生物资源却遭到了过度的开发和利用。
现在,我们正面临着很多严重的生态问题:
在许多地方,不但生物资源已经陷入了枯竭的境地,而且野生动物赖以生存的栖息地的环境也在不断恶化,其面积不断减小;大量的原始森林遭到了过度地砍伐;草场退化;湿地面积减小;土壤沙漠化和盐碱化日益严重;水资源面临枯竭……
甚至已经到了难以恢复的程度。如果任其发展下去,未来二十年将是生物物种大量消失的时期。据预测,到2050年,地球上的物种将有四分之一陷入灭绝的境地。生物链一旦断裂,将直接威胁到人类自身的生存与发展。警钟已经响起,保护生物多样性的工作刻不容缓。
想要我们的生物的多样性不消失,我们应该这样做:
1.建立自然保护区。
2.迁地保护。
3.科学研究保护。
4.法律保护,加强法制教育管理。
同学们!让我们一起保护生物的多样性,不要让生物的多样性在2050年毁灭!
从现在起,让我们一起努力吧!
