Economics, however, may be a much greater problem than scientific disagreement for people who want to protect the environment. It is clear that the chemical industry is an important business in many countries. If the government reduces the number of chemicals which are used today, the chemical industry will experience economic problems. Companies will reduce the number of people they employ. If unemployment increases and if the industry earns less money, the economy of the whole country will suffer. If a country’s economy is bad, people will blame the government. Consequently, governments may be reluctant to pass laws that will immediately damage their economy.
