如果人类都吃素,世界将会怎样?

2016-04-05 佚名 生物谷

就算你不是一名素食主义者,那么你身边也肯定至少有一位只吃素的朋友。根据所在的国家地区不同,周围的素食主义者群体的规模也可大可小。例如,美国境内的素食主义者占据4%-5%,然而在印度则高达30%。我们不妨假设一下, 如果全世界都是素食主义者的话,世界将会怎么样呢? 研究结果显示,如果这种情况真的出现,那么将有200亿只肉鸡,150亿只肉牛以及超过10亿只肉羊将会失去使用价值。 难以想象,如果我

就算你不是一名素食主义者,那么你身边也肯定至少有一位只吃素的朋友。根据所在的国家地区不同,周围的素食主义者群体的规模也可大可小。例如,美国境内的素食主义者占据4%-5%,然而在印度则高达30%。我们不妨假设一下, 如果全世界都是素食主义者的话,世界将会怎么样呢?

研究结果显示,如果这种情况真的出现,那么将有200亿只肉鸡,150亿只肉牛以及超过10亿只肉羊将会失去使用价值。

难以想象,如果我们不再食用这些饲养动物的话应该怎么处理它们,不过大部分饲养的动物将会因为失去市场而不复存在,之后,就能够释放大量的土地资源(大约3300万平方公里),这有多大呢?大约相当于整个非洲的面积。

然而,这仅仅是圈养动物的土地,还不包括为了饲养动物种植的饲料所占的土地面积。

那么,我们现在拥有了大量闲置的土地,将用来干什么好呢?首先,肯定是为全球的素食主义者们种植足够的蔬菜与庄稼,不过问题在于,虽然其中一部分土地仍适合耕种,但其它大量土地过于干燥难以种植庄稼,必须施加化肥。

"如果不及时施加人工养分,大量土地将变成沙漠。"

不过如果处理得当,其中一些土地将会重新变成森林或草原,这将有效缓解气候变化带来的危机。

说道气候变化,仅仅饲养牛所排放的温室气体的量就达到了可怕的程度,因此养牛行业的消失将会对全球气候产生巨大的正面影响。

另外,我们将因此节省大量的水资源,毕竟世界上70%的淡水资源都被用于农业生产。

那么问题解决了,我们明天起鼓励大家全吃素不就行了吗?不过,事实上并非这么简单。毕竟让世界上每一个人都放弃美味的牛排并非易事。

近日,一篇刊登于国际杂志Science上的研究论文中,来自英国布里斯托尔大学的研究人员通过研究人工模拟出了一种关键的光敏分子,或可帮助开发新型方法来制造光敏人工细胞。 文章中,研究人员Jonathan Clayden及其同事开发了一种人工模拟的视网膜紫质,视网膜紫质是一种位于视网膜细胞膜中的特殊蛋白,通过视网膜紫质进行的光吸收是视觉生物化学作用的第一步。 利用结合在细胞膜上的某些抗生素的分子

Nature:神经细胞的重生之谜

长期以来神经科学家一直认为瘢痕组织是通过神经胶质细胞形成的,神经胶质细胞是中枢神经系统中围绕在神经元周围的特殊细胞,当大脑或脊髓受损时其可以阻碍损伤的神经细胞继续生长,因此难怪研究者们会假设如果他们寻找到一种移除或中和疤痕组织的方法,那么损伤的神经元细胞或许就会进行自我修复。 近日刊登在国际杂志Nature上的一项研究论文中,来自加州大学洛杉矶分校的研究人员通过研究发现,研究者们的上述假设或许

这张“浪漫”的图表告诉你未来可能离婚的概率

  尽管我们每个人对婚姻都有着美好的祝愿,但并非每一桩婚事都能够长久下去。美国目前的离婚率高达50%,其它国家也不在少数。那么你怎么知道自己是不是其中一员呢? 科学家们根据个人的各方面因素制成了一个公式,并制作出一张图表,该图表能够帮助大家估计自己未来离婚的可能性,其中包括:工作情况,教育水平,种族背景。根据自身情况的特异性,也许事实会比我们预想的要好。 该图表是由统计学家N

Cell:特殊脂肪组织如何开启机体的节能模式

近日,来自德国马克斯普朗克研究所(Max Planck Institute)的研究人员通过研究发现,大脑细胞不仅会告知饥饿的小鼠去寻找食物,而且还会通过机体棕色脂肪来限制血糖的使用,该机制或可确保在食物量不足的情况下小鼠依然保持足够的生存率,相关研究刊登于国际杂志Cell上。 当我们饥饿的时候会发生什么?我们的大脑如何控制能量消耗?为了回答这些问题,研究人员Jens Bruning及其同事分析

Nature:生男还是生女?古老病毒来决定

近日,一项刊登在Nature杂志上的研究中,来自耶鲁大学的科学家发表了一项突破性的研究成果,他们发现人类及其他哺乳动物的性别早在150万年前就由“嵌入”哺乳动物基因组中的关键病毒的一种简单修饰所确定了。研究者Andrew Xiao指出,从根本上来说,这些病毒可以促使哺乳动物的基因组不断进化,但同时其却带来了一定的不确定性,除了胚胎之外,科学家们发现这些病毒活跃的场所就是人类机体的肿瘤和神经元

Nature:科学家揭秘常见脑血管疾病的发病机制

大脑海绵状血管畸形(CCMs)是大脑中薄壁血管膨胀的一种集群形式,其会引发中风和癫痫发作,然而具体发病机制目前研究者尚不清楚;近日来自宾夕法尼亚大学的研究人员通过研究发现了隐藏在这种脑血管疾病发生背后的一种新型的分子机制,相关研究刊登于Nature杂志上。 通常在100至200人中会有一名大脑海绵状血管畸形患者,该疾病主要表现为两种方式,第一种是散发状态,占到了80%的患者,另外一种则是遗传性
