问题         Recognizing the enormous contribution that plants make to successful remedies, the Trust has provided 9.2 million pounds towards the building itself which will be known as the Welcome Trust Millennium Building.Much of the remaining cost will be sought from international funding agencies.
        Why do we need to conserve plants?
        Within fifty years, one quarter of the world’ s plants could be condemned to extinction.Should this happen, many thousands of animals will disappear as well, but perhaps most importantly, the human cost will be huge.As well as providing staple food crops, plants are the source of a great many medicines, and form the principal supply of fuel and building materials in many parts of the world.They also protect the soil and help to regulate the climate.However, plants are often lost before we know anything about their potential benefits for society.
        Why do we need seed banks?
        We would always like plants and their habitats to be conserved in the wild.Sadly, pressures on the environment are so great that it is not always possible to do this.Because we can’ t always guarantee the safety of a plant in its natural environment, banking seeds provides an effective form of insurance.Seed banks are a very efficient and cost-effective means of conserving plant species because seeds occupy very little space and require little attention.
        Many thousands of seeds for each species are stored in a seed bank.Each seed represents a potential new plant.Life’ s strength is in its diversity, so the greater variety of seeds we store for each species, the more we can guarantee that species’ safe future.
        Aims of the Millennium Seed Bank
        The project aims to collect and conserve seeds from the entire UK native seed-bearing flora by the year 2000.Through international collaboration the aim is to bank 24, 000 species, principally from the world’ s drylands, by 2010.
选项
答案 Environment protection
解析 根据表格中 空缺处前的信息“Reason behind Plants Conservation”，即“植物保护的原因”，可定位至文中的小标题“Why do we need to conserve plants?”。 由小标题下段落可知，植物保护是为了防止植物物种灭亡引发的多重灾难。该段还提到了植被对自然和人类社会的诸多益处。总体来说，可以总结为环境保护，故本空填Environment protection。
