At that time, concern about the environment was not so far advanced as it is today, and some aspects have been alleviated by recent developments: the use of CFCs in refrigeration has now largely been abandoned, which has had some effect in slowing the destruction of the ozone layer; the introduction of managed forests is now much more widespread; the expansion of recycling initiatives, the development of renewable energy supplies and the control of fossil fuel emissions have all been considerable; the take-up of electric cars has been so rapid as to overtake the provision of the associated infrastructure that will be required; plastics, once regarded as the industry standard for manufactured goods, have suddenly become less acceptable as “whole of life” criteria become a major factor in the field of marketing, resulting in a vastly increased focus on sustainability.
