In terms of the future of the transportation sector and how automation has a role in that, I think it really does come down to the supply chain players themselves as to how that gets integrated into their workforce, so I would really defer to the expertise of folks working within the trucking and rail industries.
I think from our end, in the fertilizer sector, it's really about the levels of service received from the supply chain players but also about the reliability and redundancy of the system. If automation can support that in a safe, secure and efficient way, then definitely I think it's something to be considered going forward.
