发展的压力，特别是在热带国家，正在造成物种灭绝速度的惊人增长，这使得当前系统的复苏特别及时。假设有合理的估计，系统主义者仅发现并命名了地球上大约10％的物种，而且对这些物种中只有很小一部分进行了详细研究，所以在很短的时间内要做很多工作。许多物种在我们甚至还不认识它们之前就已经灭绝了，这也就不足为奇了，系统主义者会感觉好像他们在准备卡片目录之前（或者甚至没有人读过1％的书籍之前）正在看着巨大的图书馆被烧毁。 。所有植物，开花植物以及研究较少的藻类，苔藓，蕨类和真菌（包括地衣）都需要专家。这种集中力适合计划在
Pressures of development, particularly in tropical countries, are causing an alarming increase in the rate of species extinction, making the current resurgence in systematics especially timely. Given the reasonable estimate that systematists have only discovered and named perhaps 10% of the species on earth, and the fact that only a tiny fraction of those species have been studied in any detail, there is much work to be done in a short time. Many species will go extinct before we even know them, it is no wonder that systematists feel as though they are watching a huge, diverse library burn down before a card catalog has been prepared (or before anyone has read even 1% of the books). Specialists are needed in all groups of plants, flowering plants as well as the less heavily studied algae, mosses, ferns and fungi (including lichens). This concentration is appropriate for students planning graduate studies in these areas. More immediate employment possibilities are in the National Park Service, state and natural heritage and endangered plant programs, private consulting firms, conservation organizations, botanic gardens, and herbaria. Systematic biology is a good way to indulge urges to travel, do science, and contribute to society, all at the same time.
