It was reported in 1999 that fewer than one in four persons in the European Union regarded the fight against pollution as a problem for the future, and only one in 25 felt that pollution was not really a problem. While as much as 90% of Greeks considered the problem to be an immediate one, their sense of urgency was shared by just over half of those polled in France. On the whole, the Europeans who were most convinced of the urgent need for an "ecological" combat were in the 25-54 age group. They were rather well-educated and had above-average incomes. Eight Europeans out of 10 felt they were living on an endangered planet. A mere 10% of Europeans believed that human activities were not harmful to the environment. Europeans were most concerned about air, water and soil pollution, which they ranked just ahead of the destruction of the ozone layer when considering environmental problems in general. But traffic problems, followed by air pollution, were their chief preoccupations at a purely personal level. In future two Europeans out of three would be ready to pay more for certain products in order to protect the environment. Food topped this particular list, followed by water. But people were much less keen to pay more for other goods and services, including cars, motorcycles and air travel.
