Animal experimentation has been subject to legislative control in the United Kingdom since 1876. This paper reviews the impact of that legislation, which was replaced in 1986, on the teaching of practical physiology to undergraduate students. Highlights and case studies are also presented, drawing on Government reports and statistics, published books and papers, and unpublished archival data.

Plantation agriculture is more than 400 years old and contributes to the regional and national economies in many tropical countries. This paper reviews some of the main environmental issues related to plantation agriculture with perennial crops, including soil erosion, soil fertility decline, pollution, carbon sequestration and biodiversity. Soil erosion and soil fertility decline are of concern in some areas, but in most plantations these are being checked by cover crops and inorganic fertilizer applications. Few studies have been conducted on the issue of carbon sequestration under perennial plantation cropping. Reductions in deforestation yield much greater benefits for a reduction in CO2 emissions than expanding plantation agriculture. The biggest threat to biodiversity is the loss of habitat through expansion of the plantation area. Despite the environmental problems and concerns, this review has shown that crop yields of most perennial crops have increased over time due to improved crop husbandry including high-yielding cultivars and improved soil management. It is likely that more attention will be given to the environmental aspects of plantation cropping due to the increasing environmental awareness in tropical countries.
