 I think in America, we minimize the degree of the illness that is caused by various types of chemical exposure. The idea that children are coming down to one element after another because they're breathing chemicals in the air clearly is not acceptable to me. And if elected president, this is an issue, we will put a lot of resources into any situation we will try to end. And certainly it's not just California. In urban areas all over this country, we have outrageously high rates of childhood asthma. And this is something that when we talk about health care, we have to understand that these type of pollutants cannot be allowed to continue to poison the children of our country. Second of all, it is my view that not only because of the pollutants, not only because of the release of methane, but because of the concern that many of us have about the future of clean water in the United States of America. We have got to end fracking. It is just not worth the risk to poison our aquifers at a time when we are seeing the kind of damage we are from climate change and drought. We have to be very, very conservative in making sure that we protect our water supply and fracking moves us in exactly the wrong direction. So I applaud the families who have come out, the individuals who have spoken out against this very serious problem here and we look forward to working with them. Any questions on environmental issues? Senator, you heard from the families from Porter Ranch who are regular by the natural gas leak. What can be done on the federal level to help these people? Well a lot can be done. We have to hold the companies accountable. And most importantly what we have got to do is transform our energy system away from fossil fuel to energy efficiency and sustainable energy. There is huge potential and we are seeing it here in California. We are seeing the growing utilization of wind turbines and of solar. If elected president we will greatly accelerate that transformation. We have the technology now, we have the knowledge and research and development will only make sustainable energies even more cost effective. But right now we can do a lot more with solar, we can do a lot more with wind, with geothermal and with other technologies and we can create in this process just a whole heck of a lot of good paying jobs as we move away from fossil fuel to energy efficiency and sustainable energy.
