Cod fishing in Newfoundland was one of the best in the world. When the Canadian state lifted restrictions in , the cod population was over-fished and collapsed in It has not recovered.

Toward a New Concept of Catchment

In addition, 40 people in the fishing sector lost their livelihood. Obviously, the environment needs to be functional to allow for a functioning economy. Several means to work towards that goal have been introduced. This is developed systematically in the so-called environmental management systems EMS. It is not surprising. The investments needed to introduce cleaner.

Almost any activity may have its own environmental management system.

The concern regarding a product does not stop at its production; the extraction of resources needed. Sorting waste Efficient recycling at the household level is a prerequisite for good waste management in a sustainable society, here an example of Berlin. The cycle needs to be environmentally and economically sound. Instead, the rule of three Rs should be promoted: reduce, reuse, recycle. For example, not everyone needs their own copy machine, it is a piece of equipment we can use together. At the household level, waste fractionation is essential.


In the end, we need a society where material cycles go from cradle to cradle: a er a product is used, the material it consists of should come back as a resource for a new product. This is not quite true. Again, it is possible to exemplify with the energy sector. To use only renewable energy, we need technology to provide energy from solar cells, solar panels, wind and wave power stations.

Nevertheless, there is also a need for policy instruments regulations that support it. A scheme which improves the public transport and supplies renewable fuels, best electricity, for cars is important. Finally life style changes supporting living without using energy unnecessary, is also essential. As part of an experiment, some families in Stockholm were asked to live as sustainably as they could. A er a short while they were buying less, spent more time with their children, and in general found that they needed less money.

As a consequence, they reduced their working hours. Their experience illustrates some of the main themes o en brought up in discussions on how to live sustainably. Low-energy house with solar panel and cells Beddington Zero Energy Development, the United Kingdom, the largest sustainable community in the UK, was completed in The design, including solar panels and solar cells, helps the residents solve problems of heating and water use, facilitates walking rather than driving and improves the quality of life.

There is a limit to how much we may consume, but it does not necessarily lead to a decreased life quality. It is interesting to note that a recent. In the industrial West, the perceived wellbeing has been on the decline since the s. The conclusion: we were happier with less material wealth. However, some basic facts are obvious. From a distant historical perspective, we, the human society, are in a new and very critical period, well into the Anthropocene, a geological era dominated by man. With close to 6. The situation requires a transformation of our society.

We will need to rethink our energy management, our nutritional and travelling habits. A school teacher in Visby, Gotland, an island in the middle of the Baltic Sea, used to ask his pupils to design a space ship for a very long journey. They had to say what they would like to bring. The ship can only carry so much.

The kids may disagree on what is the most important, but a er much talking it turns out they agree on basic things needed to secure a reasonable life. Personal items vary.

Only a er a long discussion do they start to compare the spaceship with our planet Earth. Yet this is exactly what our planet is. It is a vehicle travelling through space, circling our life-giving Sun, with all of us on board. We will not be able to go somewhere else. Costanza R.

In the early 19th century, most people lived in a self-subsistence economy where nearly everything, from food to clothing to housing, was self-produced. Among them were blacksmiths, shoemakers, tinkers, later doctors and teachers. The major division of labour was called forth by the development of towns. We are all service users and service providers. Thus, services form the basis of our existence.

We wish to receive services both cheap and of quality.

After Socialism

Can we imagine a situation when indispensible services are provided free of charge? Not likely. To ensure services vital for human existence, the ecosystem must be whole, unspoiled. Man has not been careful to choose the means and has obtained from ecosystems more than they can yield. It is amazing that even under such conditions, ecosystems strive to adapt, restructure and preserve themselves, and we continue to receive their services. However, the self-preservation capacity of ecosystems is not inexhaustible.

Infrastructure development projects are set to continue into the next century as developing country governments seek to manage population growth, urbanization and industrialization. As you will see this is no longer the case. Chapter 3 looks at what government agencies call compliance with the law and what environmentalists are calling abuse of the law as well as abuse upon our national forest lands. Falkenmark, and J.

As a rule, we do not appreciate the things we get for free. It is high time we started receiving ecosystem services with gratitude and respecting the capacity of ecosystems to provide these services for us. For humans, water is the most important chemical compound. Life has evolved in an aquatic environment; fertilisation and development of an embryo takes place in a liquid environment. All biochemical reactions in cells occur only in an aquatic environment and involve water. Animals lose water by breathing and metabolism waste products. This is why all living organisms need constant replenishment of water.

Humans need an average consumption of two litres of water per day but can survive seven days without water at most. Death of thirst may occur in a desert just like in the ocean, which means that both the amount and the quality of water are of importance. Over the last 40 years, human consumption of water, including water for irrigation, households and industrial needs, has increased twofold.
