 I think the real challenge in environmental issues is that everything is interrelated. You're dealing here today with the nexus of agriculture, food, water and energy, but in reality there are wider implications. There are implications on the quality of the air, the implications on the soils. Those implications come from the chemical substances that we use and we all depend on ecosystems and biodiversity. So if we want to address those challenges we need to take all of those different elements into account because they all interfere with each other. One of the present day examples this year is the year of air quality in Europe. This is the way in which climate change considerations have moved the European car fleet to dependency on diesel engines. Diesel engines have the reputation of being more efficient. You take more mileage out of a barrel of diesel than out of a barrel of petrol. But the downside is that diesel engines emit fine particulates that cause real problems to humans and we have in Europe today a much worse air quality situation than the United States or Japan or any other developed partner. So it's one of the misorientations coming from overly focusing on effects on climate and forgetting that the remedy to climate problems is causing health problems to humans in Europe. This is possibly the most challenging of the issues. I think in Europe there is the beginning of an understanding of the interrelationships but many of the developing partners that we have are still desperately seeking to lift their people out of poverty and they're looking at the old development models. How has Europe developed its wealth? How has the US developed its wealth? We have done this by burning fossil fuels, by using raw materials, by cutting down our forests, by using the land to the hill. And now they are trying to do the same and we will have to convince them that resource efficiency is not only an issue for resource poor Europe but also for developing countries and that being resource efficient and becoming circular economy actually creates more jobs and therefore lifts more people long term sustainably out of poverty than the old model would ever be able of doing.
