The world’s population is expected to increase by 30 percent to 10bn people by 2050 and with 70 percent of the earth’s surface covered by water aquaculture will play an important role in producing food for the future. The paper aims to discuss this issue.

While Canada has the longest coastline in the world by far (202,080 km) with 80,000 km of marine coastline capable of supporting aquaculture and fisheries, it ranks only 25th in terms of world aquaculture production. The reasons are many and varied, and this review examines statistical reports and publications to trace the beginnings of the aquaculture sector in Canada, and highlights some areas of strength and potential, and the challenges for future growth and expansion.

Currently, less than 1 percent of the 3.8m hectares of freshwater and marine areas that are considered suitable for seafood (i.e. finfish, shellfish and aquatic plants) production are being farmed so Canada has an ocean of opportunity to be a leader in world aquaculture production in the future.

The review highlights the need for a national strategic plan to increase aquaculture production in Canada and the need to simplify the current complex regulatory framework that has resulted in significant uncertainties and delays that have limited growth in this sector. The review highlights the potential and interest to triple current production while fostering greater involvement of First Nation communities.

Dr. COLLINRIDGE, the Medical Officer of Health to the City of London, had occasion recently to call attention to the diseased condition of certain imported meats, and it is most disquieting to learn that some of these were apparently sent out from the country of origin under official certificates.

A new Guidance Note (Note EH 21) issued by the Health and Safety Executive draws attention to the health risks of exposure to various forms of carbon dust. It gives comprehensive advice on precautions which should be taken by the industries concerned.

OUR correspondents have commented upon the meagreness of the newspaper attention to the Annual Meeting of the Library Association. The opportunities which the affair would seem to afford for press comment are probably exaggerated by librarians, who quite naturally think their matters to be of importance. They are, but they have never been spectacular and are not likely to be so. What the modern pressman wants is a story ; he is not often interested in passive matters nowadays, and more than one editor has admitted that he is not concerned with what people say but with what they do. We may console ourselves to some extent by believing that our quiet work is more enduring than much that is greeted with fanfares. Snippets of facts about high issues of books, parsimony, or believed extravagance, are things that do find their way into the small paragraphs of daily papers. These may be good for our movement but there is no certainty that they are. The only sure advertisement of a library, publicly or otherwise maintained, is the quality of the service it can give.

Deaths from cardio‐vascular disease, atherosclerosis of the heart in particular, have increased in the past two or three decades at what has been called an alarming rate. In 1928, the crude death rate per million of the population for coronary disease was 137 for males and 54 for females. In 1938, it was 570 and 276 respectively. The rates for 1948 were 1,264 and 652 and by 1958 they had reached 2,208 and 1,226 respectively. The rates for the sexes have risen pari passu, maintaining about the same ratio through the years. Official statisticians have shown no disposition to regard this very great increase as entirely due to new conditions ; or to deny that in part the increase is due to improved diagnosis and also to changed methods of describing old diseases ; for example, coronary thrombosis instead of myocardial degeneration. There may also be the tendency to “over‐diagnose” coronary disease today, but despite all these factors, there is no doubt whatever that this increase and particularly the increased incidence in lower aged males has been real.

The Transfer of Functions (Food and Drugs) Order, 1955 (S.I. 1955 No. 959), providing for the transfer of certain food hygiene functions from the Minister of Agriculture, Fisheries and Food to the Minister of Health, was laid before Parliament on July 5th.

Healthcare projects face multiple obstacles in achieving sustainability. This paper aims to provide information regarding the energy consumption of healthcare facilities, to identify barriers to sustainability and to suggest methods to improve the effectiveness of these buildings.

This study investigates sustainability in healthcare buildings by examining national databases about energy use and energy savings. The authors then initiate a dialogue on this topic by interviewing experts in healthcare planning and design regarding the implications of this data, challenges to sustainability and potential solutions to these challenges.

An analysis of data from the Energy Information Administration revealed that healthcare facilities rank second among building types in the USA in energy use per square foot and rank fourth in total energy use. Data from the US Green Building Council showed that only 1 per cent of healthcare buildings are registered with the Leadership in Energy and Environmental Design rating system, and 0.4 per cent have achieved certification, which is low compared with other building types.

Research and discussion must continue engaging all stakeholders to interpret the data and identify transformative solutions to facilitate sustainable healthcare design construction and operation.

It is important to approach sustainability in healthcare from social, economic, environmental and health-related perspectives. The authors identify five major barriers to sustainable healthcare design and construction and discuss 12 practical solutions.

Given the energy demands of healthcare buildings, facilitating their sustainability has the potential to make a significant difference in national energy use. Empirical research and evidence-based design can potentially help to accelerate sustainability by clarifying impacts and documenting the economic and operational returns on investment.
