Besides, some studies show that many workaholics have great energy and interest in their own sphere领域 Their work is so pleasurable that they are actually very happy. For most workaholics, work and entertainment are the same thing. Their work challenge挑战 them, keeping them busy and genuinely engaged. Why do workaholics enjoy doing their jobs so much? Of course they get paychecks from it, but it is hard to quantify 量化the pleasure with money. It offers more than financial金融 security. Psychologists claim that work gives people an identity and provides them with self-confidence. People have a feeling of satisfaction when they administrate管理 a business well or complete a challenging piece of work. In addition, most jobs provide a socially acceptable way for people to meet others. So, thought some people are compulsive(强迫性的) about their work, their addiction 上瘾seems to be a safe or even an advantageous one. They feel empty and incomplete when they are involved in activities not related to work. 在一些城市中心，工作狂（workaholism）是如此普遍，以至于人们都不认为这是不寻常的：他们接受正常的生活方式。例如，华盛顿特区的政府工作人员每周工作60到70小时。他们这样做不是因为他们已经做了，而是因为他们想做。
工作狂可能是一个严重的问题。真正的工作狂，深深地沉浸在工作中，很少或根本没有时间休息。他们喜欢不受干扰地工作，而且可能不知道如何放松。
但是工作狂总是坏的吗？也许不是。有些人在压力下工作得很好。此外，一些研究表明，许多工作狂在他们自己的领域有很大的精力和兴趣。他们的工作很愉快，实际上他们很高兴。对于大多数工作狂来说，工作和娱乐是一样的。他们的工作对他们提出挑战，使他们保持忙碌和真诚的投入。

Farming invariably interferes with the habitats of plants and animals. However,
7 / 15
this does not necessarily mean that agriculture and biodiversity are incompatible不相容的. In fact, quite the opposite is true. The sustainable cultivation of plants for food and feed actually enables us to preserve保护 biodiversity. By 2007, there were more than twice as many people living on the planet as there were in 1961. Over the same period, the total amount of available可获得的 arable() land grew by just 10 percent. //In comparison with population growth, the expansion of arable land was small. And there are limits to further expansion. A large proportion部分 of the earth’s surface-like deserts-is not suitable for cultivation, and other areas are utilized 利用by humans for roads and buildings. Some land that is rich in biodiversity needs to be preserved and thus should not be converted转变 into arable land. The tropical rain forests, for example, have the highest species density in the world, and changing this land for crop cultivation would be dreadful 可怕的to these species’ habitats and, indeed, existence.
By 2050, global demand for food will have risen by 70 percent. But the expansion of land available for cultivation has its limits. This is one of the greatest challenges facing agriculture today: How do we balance平衡 the increased demand for food with the need to maintain biological diversity, now and in the future? Efficient and sane理智地 use of land will be key to preserving natural animal and plant habitats. To achieve this aim will depend to a(an) considerable（相当多的） extent on the use of modern agricultural methods. If these methods are successfully applied, we believe that agriculture and biodiversity can coexist in harmony.
农业总是干扰动植物的栖息地。然而，这并不一定意味着农业和生物多样性是不相容的。
8 / 15
事实上，恰恰相反。以植物为食物和饲料的可持续种植实际上使我们能够保护生物多样性。
到2007年，地球上的人口是1961年的两倍多。同期，可耕地总量仅增长了10%。//与人口增长相比，耕地面积增长幅度较小。还有进一步扩张的限制。地球表面有很大一部分像沙漠一样不适合耕种，其他地区则被人类用于道路和建筑。一些生物多样性丰富的土地需要保护，因此不应转变为耕地。例如，热带雨林的物种密度是世界上最高的，改变这片土地种植农作物对这些物种的生境和生存是可怕的。
到2050年，全球粮食需求将增长70%。但可供耕种的土地的扩张也有其局限性。这是当今农业面临的最大挑战之一：我们如何平衡粮食需求的增长和维持生物多样性的需要，现在和将来？
高效、理智地利用土地是保护自然动植物栖息地的关键。要实现这一目标，在很大程度上取决于现代农业方法的使用。如果这些方法得到成功应用，我们相信农业和生物多样性可以和谐共存。
