长篇阅读之科技篇: 科技与自然 篇一
科技与自然一直被认为是两个截然不同的领域,一个代表着人类的创造力和智慧,另一个则代表着大自然的神秘和力量。然而,在当今社会,科技和自然之间的联系却变得越来越密切。科技的发展不仅改变了人类的生活方式,也对自然环境造成了影响。
首先,科技的发展对自然环境造成了一定程度的破坏。工业化时代的到来带来了大量的工厂和机器设备,这些设备需要大量的能源来运行,导致了对自然资源的过度开采和污染。随着汽车的普及和城市化的加剧,空气和水质污染也日益严重,给自然生态系统带来了极大的压力。
其次,科技的应用也为保护自然环境提供了新的手段。随着环保意识的增强,人们开始利用科技手段来监测和治理环境污染。例如,通过遥感技术可以实时监测空气质量和森林覆盖率,通过生物技术可以研究保护濒危物种的方法。科技的进步为人类更好地理解和保护自然环境提供了新的途径。
总的来说,科技与自然并不是对立的关系,而是相互依存、相互促进的关系。人类需要在科技发展的同时保护好自然环境,才能实现可持续发展的目标。只有让科技与自然和谐共存,才能实现人类与自然的和平共处。

科技的发展给人类带来了诸多便利,但与此同时也对自然环境造成了不可忽视的影响。为了实现可持续发展,我们需要在科技与自然之间找到平衡点,最大限度地发挥科技的作用,同时保护好自然环境。
首先,科技可以帮助人类更好地保护自然环境。随着科技的进步,人类可以利用先进的技术手段来监测和治理环境污染,减少对自然资源的过度开采。例如,利用无人机和卫星技术可以实现对自然灾害的预警和监测,及时采取措施减少灾害造成的损失。科技的应用为环境保护提供了新的思路和方法。
其次,科技也可以帮助人类更好地与自然和谐共处。传统的农业生产方式往往对土地和水资源造成破坏,而现代农业技术可以实现高效、节约的生产,减少对自然环境的影响。同时,生物技术的发展也为人类提供了更多与自然和谐共处的可能性,例如通过基因编辑技术研发耐旱、耐病的作物品种,减少对化肥和农药的使用,保护土地和水资源。
综上所述,科技与自然并不是对立的关系,而是相互依存、相互促进的关系。人类需要更加注重科技与自然的和谐发展,不断探索科技创新和环境保护的平衡点,共同实现可持续发展的目标。只有在科技与自然和谐共存的基础上,人类才能实现真正的繁荣与进步。

Technology that imitates nature
Biomimetics: Engineers are increasingly taking a leaf out of nature's book when looking for solutions to design problems
<--back-->
AFTER taking his dog for a walk one day in the early 1940s, George de Mestral, a Swiss inventor, became curious about the seeds of the burdock plant that had attached themselves to his clothes and to the dog's fur. Under a microscope, he looked closely at the hook-and
-loop system that the seeds have evolved to hitchhike on passing animals and aid pollination, and he realised that the same approach could be used to join other things together. The result was Velcr a product that was arguably more than three billion years in the making, since that is how long the natural mechanism that inspired it took to evolve.Velcro is probably the most famous and certainly the most successful example of biological mimicry, or “biomimetics”. In fields from robotics to materials science, technologists are increasingly borrowing ideas from nature, and with good reason: nature's designs have, by definition, stood the test of time, so it would be foolish to ignore them. Yet transplanting natural designs into man-made technologies is still a hit-or-miss affair.
Engineers depend on biologists to discover interesting mechanisms for them to exploit, says Julian Vincent, the director of the Centre for Biomimetic and Natural Technologies at the University of Bath in England. So he and his colleagues have been working on a scheme to enable engineers to bypass the biologists and tap into nature's ingenuity directly, via a database of “biological patents”. The idea is that this database will let anyone search through a wide range of biological mechanisms and properties to find natural solutions to technological problems.
How not to reinvent the wheel
Surely human intellect, and the deliberate application of design knowledge,
