what is important for the species to continue

Answer:
Hope it will help you
Explanation:
Humans depend on biodiversity in myriad ways, yet species are being rapidly lost due to human activities. The ecosystem services approach to conservation tries to establish the value that society derives from the natural world such that the true cost of proposed development actions becomes apparent to decision makers. Species are an integral component of ecosystems, and the value they provide in terms of services should be a standard part of ecosystem assessments. However, assessing the value of species is difficult and will always remain incomplete. Some of the most difficult species’ benefits to assess are those that accrue unexpectedly or are wholly unanticipated. In this review, we consider recent examples from a wide variety of species and a diverse set of ecosystem services that illustrate this point and support the application of the precautionary principle to decisions affecting the natural world.

Introduction
The ongoing growth in human population and resource consumption is changing the planet in fundamental ways. One consequence of this growth is the loss of biodiversity, which is typically estimated either by the net movement of species towards higher categories of extinction risk or as the rate at which species are actually going extinct. By either measure, biodiversity loss is on the rise. As species disappear we lose both known and unknown benefits they provide. We begin this review by discussing some well-known examples of the importance of species (Box 1). We then proceed to answer the question: ‘what have species done for me lately?’ The short answer is: ‘plenty!’
Box 1
Well-known examples of benefits provided by species to humanity.
The best-known benefits are those related to either providing food or facilitating recreation and other cultural activities. Globally, fishers catch >90 million tons of fish each year for human consumption, representing more than 8% of the animal protein consumed. Nearly 40 million people fulltime are employed in fishing directly. Fish exports from the developing world — including aquaculture, which accounts for about half — are worth more than all other agricultural commodities combined [76]. The commercial value of fish is staggering, but fish are often worth a lot even when they are not sold. Consider all of the people who travel to see colorful fish on coral reefs. Consider, too, recreational fishers (33.1 million in the U.S. and about 25 million in Europe 77, 78). Hunting terrestrial mammals or birds for subsistence and sport has similar importance. Millions of people travel to see mammals and birds in far-flung countries.
Classic indirect benefits from species include those derived from the fungus Penicillium chrysogenum, from which the antibiotic penicillin was isolated.
