Global warming, BSE, exhaustion of the planet’s natural resources: new problems distress humanity and those who should be leading us across the ford not always rise to the occasion.

Even though distracted by the endless series of daily problems, public opinion is starting to pay more attention to the issues which have a medium/long-tern significance, that is to the prospect of epoch-making transformations resulting from the growing impact of man’s activity on nature: the greenhouse effect, deforestation, the outbreak of new diseases, the depletion of energy supplies, the extinction of an ever increasing number of animal and vegetable species, the insufficiency of water resources, genetic manipulation, and even certain new inventions.

Let us start with the greenhouse effect: up to about ten years ago, most people regarded it as some sort of urban legend, a rather science-fiction idea which certain scientists made use of to obtain funds and to be talked about.

There were really few people who believed that spray cans could cause holes in the ozone layer, that exhaust emission could warm the atmosphere to the point of causing the polar icecap to melt, the global sea level to rise or dramatic climate shifts. Today, with this whirlwind of concerns we are bombarded with every day, also from the United Nations, as to potentially catastrophic events foreseen within a relatively short period of time, people are actually starting to believe it. When it was signed, very few knew the actual contents of the Kyoto Protocol for the progressive reduction of noxious gasses; now that the conference which was supposed to implement the agreement has miserably failed, people are getting anxious and worried about the future. The dispute between the United States, who also want to include the ecological investments made in the Third World, and Europe, who on the other hand claims that each country should bear its own spending cuts, has caused arguments even among outsiders.

In other words, the greenhouse effect is no longer a right-wing or a left-wing problem, but has become A PROBLEM to all intents and purposes; and besides the so-called population of Seattle, it now also affects businessmen, tour operators, engineers and so on.

A problem which is strictly related to the greenhouse effect, is the apprehension arising from the systematic destruction of the equatorial forests, proper oxygen manufactures, which continue to represent the most effective antidote against the excessive production of carbon dioxide: maybe one person out of a hundred has actually had the opportunity to see with his/her own eyes what deforestation actually means, and if we did not read newspapers or watch TV we would not even know about its existence.

Still, when we are informed that the surface of these “lungs of the world” is reduced each year by 1%, because it is difficult to stop a very profitable business and emergent countries need new land to farm in order to nourish an ever growing population, we start asking ourselves how it will be possible to replace the air we breath in a century’s time, when the forests will have ceased to exist. Fear, fear, fear: this seems to be one of the peculiarities of today’s man.

Among the many psychological, alimentary and economical effects of the BSE disease, we should for instance also mention the dread at the thought of the uncontrolled spreading of a disease so far unknown, and at the moment incurable, such as the so-called variant Creutzfeld-Jacob disease. In the industrialised world, the fear of AIDS has in the meantime slightly eased, because we have learned more about the contagion mechanisms and because pharmacology has found a way of prolonging patients’ lives, even thought at very high prices.

But those who are following the developments of the situation in Sub-Saharan Africa know that, over there, 25 to 33% of the population is HIV-positive, that in countries such as Zambia and Zimbabwe AIDS has cruelly claimed the lives of generations of twenty- and thirty-year-old people, leaving behind millions of orphans, and that within the next 50 years the population in this area may actually be reduced by 50%. Having temporarily laid aside the AIDS psychosis, Europe is now panicking about the BSE disease. From a logical point of view, this is a rather irrational fear. In countries which make use each year of hundreds of billions of cigarettes, even though cigarette packs bear warning labels saying that they represent a serious hazard for people’s health, and it is statistically proved than dozens of thousands of smokers die from lung cancer each year, people have, from one day to the next, cut down on meat consumption by 20, 30, 40, and even 50 per cent, for fear of a contagion which today is still highly unlikely. In Great Britain, where the “mad cow” problem first broke out, the people who have died from the variant Creutzfeld-Jacob disease have been less than one hundred in fifteen years, whereas in the remaining part of Europe the victims can be counted on the fingers of one hand. It is quite true that, according to scientists, the incubation period for this disease ranges from 5 to 30 years, and that therefore, in theory, we may already all be vectors. It is also true that, based on what we have seen on TV, death by BSE is rather horrible. But, based on the poor information we have available at the moment on the disease transmission mechanism, it would appear that the risk of developing it is really very low for human beings, and that eating beef at the moment is not more dangerous than riding a motorbike. Whilst in doubt, we eat chicken, awaiting that the BSE disease stops being a news item and that some other collective fear takes its place. But the greenhouse effect and the fear of epidemics are not our only causes for anguish. There also is a much more tangible fear, an issue which was first raised almost fifty years ago by the so-called “Club di Roma”, which was shelved for a certain period of time and which has recently resurfaced: the issue that man, by pursuing progress as if it were its only god, is about to run out of the resources offered by the planet, which means that future generations will find themselves without hydrocarbons, without water, and possibly without other things which are unlikely to be replaceable. We are here exiting the reign of irrationality and returning to the much more solid area of economic forecasting. It is true that the fear of being left without oil had already made its appearance in the 70s, when we were hit by the first great wave of rising prices, and that the busy research work which followed that shock has enable us to restore supplies which will last us for at least one more generation.

But now that we are learning to think in terms of long-range prospects, we cannot but question what will happen when we shall have really scraped the bottom of the barrel. We are now preparing to replace one of the kings of the 20th century, the internal-combustion engine, which something absolutely revolutionary.

We have all enthusiastically plunged into the Internet world, even though only a minority of us understands how the system actually works. But since there are so many things which are difficult to understand, everything seems to convey to us a subtle sense of uneasiness. I personally share none of the protests against globalisation, the even violent attempts to stop progress and freeze the world, so to speak. But we cannot deny that progress is generating new problems, which we are not very well equipped to deal with. There is an evident confusion as to areas of competence, not to mention continuous power struggles. We then have the conflict, which is nothing new, between science and religion, and in certain cases even between science and ordinary morality.

How far can we go with genetic manipulation, assisted procreation and the other practices of the new frontier?

It is out of question that, at present, science could solve many problems, but again fear of the unknown stops it, as in the case of transgenic food, which have so far not proved to be harmful in any way but which millions of people refuse to eat. There is no doubt that the 21st century has the potential for becoming the best in the history of humanity.

However, we need to avoid overspeeding, slow down at bends and, if the engine starts to race, make sure we see to it in time.
