 There's no problem necessarily as such with exploration being undertaken by entities that are not governments. Governments themselves have their own incentives, which are not always such positive incentives. So there's possibilities for commercialization that could be beneficial. I don't think that we should rule that out. But obviously it does raise interesting and important issues of regulation. So there's questions of risk, both of space exploration to those engaged in it, both also to the ecosystems insofar as there are ecosystems that become explorable through space exploration, and then also risks insofar as people are exploring space what the effects are going to be having on people who are on Earth. So obviously you need to have a framework in place that has a fair and sound allocation of risk in these kinds of activities. And again, that's something that we need right here on planet Earth as well. So commercial entities want to do things like explore the deep seabed resources. Again, there's no necessarily problem as such, but the question is on what terms and how and how are the costs and risks managed.
