| 9 | Animals are clearly important to us, so it's equally important that we avoid causing them | 动物显然对我们很重要 所以我们同样重要的是要避免引起它们 |
| 10 | unnecessary pain. | 不必要的痛苦。 |
| 11 | For animals that are similar to us, like mammals, it's often obvious when they're hurting. | 对于和我们相似的动物来说,像哺乳动物一样,伤害时往往很明显. |
| 12 | But there's a lot that isn't obvious, like whether pain relievers that work on us also | 但是很多事情并不明显,比如 减轻我们痛苦的药剂 |
| 13 | help them. | 帮助他们 |
| 14 | And the more different an animal is from us, the harder it is to understand their experience. | 动物越与我们不同,就越难理解他们的经验。 |
| 15 | How do you tell whether a shrimp is in pain? | 如何分辨虾子是否痛? |
| 16 | A snake? | 一条蛇? |
| 17 | A snail? | 蜗牛? |
| 18 | In vertebrates, including humans, pain can be split into two distinct processes. | 在脊椎动物中,包括人类,疼痛可以分为两个截然不同的过程. |
| 19 | In the first, nerves in the skin sense something harmful and communicate that information to | 首先,皮肤神经感知到一些有害的东西,并将这些信息传递给 |
| 20 | the spinal cord. | 脊髓 |
| 21 | There, motor neurons activate movements that make us rapidly jerk away from the threat. | 在那里,运动神经元 激活移动 使我们迅速摆脱威胁。 |
| 22 | This is the physical recognition of harm, called nociception. | 这是对伤害的物理识别,称为鼻吸. |
| 23 | And nearly all animals, even those with very simple nervous systems, experience it. | 几乎所有的动物,即使是那些神经系统非常简单的动物,都会经历它。 |
| 24 | Without this ability, animals would be unable to avoid harm, and their survival would be threatened. | 没有这种能力,动物就无法避免伤害,它们的生存也会受到威胁. |
| 25 | The second part is the conscious recognition of harm. | 第二部分是自觉承认损害。 |
| 26 | In humans, this occurs when the sensory neurons in our skin make a second round of connections, | 在人类中,当我们皮肤中的感官神经元 进行第二轮连接时, |
| 27 | via the spinal cord to the brain. | 通过脊髓到大脑。 |
| 28 | There, millions of neurons in multiple regions create the sensations of pain. | 在那里,多个地区的数百万神经元产生疼痛的感觉. |
| 29 | For us, this is a very complex experience, associated with emotions like fear, panic, | 对我们来说,这是一个非常复杂的经历, 与情绪有关,如恐惧,恐慌, |
| 30 | and stress, which we can communicate to others. | 和压力,我们可以与其他人沟通。 |
| 31 | But it's harder to know exactly how animals experience this part of the process, because | 但更难知道动物是如何经历 这部分过程,因为 |
| 32 | most of them can't show us what they feel. | 他们大多不能告诉我们他们的感受。 |
| 33 | However, we get clues from observing how animals behave. | 然而,我们从观察动物的行为中获得线索。 |
| 34 | Wild, hurt animals are known to nurse their wounds, make noises to show their distress, | 野生的,受伤的动物 已知会抚育他们的伤口, 制造噪音来显示他们的烦恼, |
| 35 | and become reclusive. | 并变得隐蔽。 |
| 36 | In the lab, scientists have discovered that animals like chickens and rats will self-administer | 在实验室,科学家发现,像鸡和老鼠这样的动物 会自我管理 |
| 37 | to pain-reducing drugs if they're hurting. | 减少疼痛的药物,如果他们伤害。 |
| 38 | Animals also avoid situations where they've been hurt before, which suggests awareness | 动物也避免了以前受伤的情况 这说明他们意识到 |
| 39 | of threats. | 威胁。 |
| 40 | We've reached the point that research has made us so sure that vertebrates recognize | 我们已经到了研究的地步 使得脊椎动物认识到 |
| 41 | pain that it's illegal in many countries to needlessly harm these animals. | 痛苦的是,在许多国家,不必要地伤害这些动物是非法的。 |
| 42 | But what about other types of animals, like invertebrates? | 但是其他种类的动物呢,比如无脊椎动物? |
| 43 | These animals aren't legally protected, partly because their behaviors are harder to read. | 这些动物没有受到法律保护,部分原因是他们的行为更难阅读. |
| 44 | We can make good guesses about some of them, like oysters, worms, and jellyfish. | 我们可以很好地猜测其中的一些, 比如牡蛎,蠕虫,水母。 |
| 45 | These are examples of animals that either lack a brain or have a very simple one. | 这些是动物缺乏大脑或非常简单的例子。 |
| 46 | So an oyster may recoil when squirted with lemon juice, for instance, because of no suception. | 因此,牡蛎在用柠檬汁浇灌时可能会后坐,例如,因为没有吸积. |
| 47 | But with such a simple nervous system, it's unlikely to experience the conscious part | 但是,有了这么简单的神经系统, 它不可能经历意识的部分 |
| 48 | of pain. | 痛苦的记忆 |
| 49 | Other invertebrate animals are more complicated, though, like the octopus, which has a sophisticated | 其他无脊椎动物 更复杂,虽然, 像章鱼,它有一个复杂的 |
| 50 | brain and is thought to be one of the most intelligent invertebrate animals. | 大脑被认为是最聪明的无脊椎动物之一. |
| 51 | Yet, in many countries, people continue the practice of eating live octopus. | 然而,在许多国家,人们继续吃活的章鱼。 |
| 52 | We also boil live crayfish, shrimp, and crabs, even though we don't really know how they're | 我们还煮活鱼、虾和螃蟹 虽然我们不知道它们是什么 |
| 53 | affected either. | 也受到影响。 |
| 54 | This poses an ethical problem, because we may be causing these animals unnecessary suffering. | 这造成了道德问题,因为我们可能给这些动物带来不必要的痛苦. |
| 55 | Scientific experimentation, though controversial, gives us some clues. | 科学实验虽然有争议,但给我们提供了一些线索. |
| 56 | Tests on hermit crabs show that they'll leave an undesirable shell if they're zapped with | 对隐士蟹的检测显示,如果它们被缠住,它们会留下一个不受欢迎的壳. |
| 57 | electricity, but stay if it's a good shell. | 电力,但如果它是一个好的壳。 |
| 58 | And octopi that might originally curl up an injured arm to protect it will risk using | 原本会卷起受伤的手臂来保护它的 octopi 将冒着使用 |
| 59 | it to catch prey. | 捕捉猎物。 |
| 60 | That suggests that these animals make value judgments around sensory input instead of | 这意味着这些动物 围绕感官输入进行价值判断 而不是 |
| 61 | just reacting reflexively to harm. | 只是反应反射 伤害。 |
| 62 | Meanwhile, crabs have been known to repeatedly rub a spot on their bodies where they've | 同时,人们知道 螃蟹在身体上反复涂抹斑点 |
| 63 | received an electric shock. | 受到电击 |
| 64 | And even sea slugs flinch when they know they're about to receive a noxious stimulus. | 即使是海弹,当他们知道 他们即将得到 有毒刺激。 |
| 65 | That means they have some memory of physical sensations. | 这意味着他们有一些记忆 身体的感觉。 |
| 66 | We still have a lot to learn about animal pain. | 我们仍然有很多关于动物痛苦的知识。 |
| 67 | As our knowledge grows, it may one day allow us to live in a world where we don't cause | 随着我们知识的增长,它也许有一天会让我们生活在一个我们不导致的世界上 |
| 68 | pain needlessly. | 无谓的疼痛。 |
