The idea that the growing demand for energy worldwide can be met with energy from nuclear power is nonsense.

But, as environment minister, I am very interested in a thriving German automobile industry, because I can only pay for the rising costs of environmental protection at home and abroad if there are people in Germany with jobs and who pay taxes.

It is clear that Germany needs a foreign policy in which we jointly define European interests. Thus far, we have often defined European values, but we have been much too weak in defining mutual interests. To preempt any possible misunderstandings: We cannot give short shrift to our values of freedom, democracy and human rights.

The new social question is: democracy or the rule of the financial markets. We are currently witnessing the end of an era. The neoliberal ideology has failed worldwide. The U.S. movement Occupy Wall Street is a good example of this.

We need a greening of globalisation.

A major danger for us Europeans: We must demonstrate that those who have this view of us are mistaken, that we can come to agreement, that we as a community of democratic and free nations are economically successful and are gaining political influence. To do so, we must learn to project our power.

The production of natural resources in agriculture, forestry and fisheries, stable natural hydrological cycles, fertile soils, a balanced climate and numerous other vital ecosystem services can only be permanently secured through the protection and sustainable use of biological diversity.
