I prefer the standard quote from the World Commission on Environment and Development (WCED) in that sustainability is 'meeting the needs of the present without compromising the ability of future generations to meet their own needs.' However Hall (2006 p156) states that this definition is “idealistic and somewhat impractical definition of sustainable development”.
I also think that there are threats to how we can secure sustainability in the future and in particular this country
1) Education- Several areas including that of the school curriculum does not really address what sustainability and how people can try to be sustainable. Also it has taken too long to get the issue onto the school curriculum and in my case not learning about it until in higher education.
2) Cost- Trying to be sustainable can cost considerable amounts of money, such as new recycling schemes or trying to combat climate change with the aid of wind farms and solar panels. This can put off a lot of people such as small companies that may not think the benefits outweigh the costs.
3) Ignorance- Some people may choose to ignore the need to be sustainable in that they may only be thinking of the present and not what the future entails for future generations. We know for instance about how we should import goods locally cutting down on greenhouse emissions but instead we want the latest electronic goods from Japan or a different variety of tomato.
4) Culture- We are a country that wants everything and wants it now, with no regard for the environment new car ownership being one. Hall (2006) states that as a nation our government tries to ensure economic growth, this in turn increases living standards and therefore increases personal consumption.
5) Financial worries- We are officially in a recession so everyone is tightening their belts. With these times people are less concerned about being sustainable and are more concerned about where the next pound is coming from. Also with the added worry of the recession this can affect people’s health in the long and short term affecting employment levels.
6) Lack of government action- The Prime Minister admits there is a threat to the long term issues of sustainability however states that these long term problems occur over several political time scales so may be on different agendas of different political parties. This can be a threat in that issue’s can be left behind in favour of other issues unrelated to sustainable development.
There will always be threats to how we can secure sustainability for the present and for future generation, however these threats can be overcome with a bit of planning and forward thinking.
