Why?

Perhaps I live in a utopic haze, but can anyone help me understand this photo?

Note the atv and ski doo tracks on the left side of the sign, leading out to a very sensitive ecological area on the N Saskatchewan River. Prior to the change in land use framework, we used to float the river once or twice each spring and fall and have atvs ripping down the river bank to stay ahead of us, to ensure those on the atvs could get to the next pool to fish first. They'd rip donuts in the gravel and tear wherever they wanted. They completely missed the point of the location. The Kootenay Plains, tucked beside Banff National Park, receive such small amounts of precipitation and endure winter like conditions much of the year. It's an anomaly filled area. Life takes time to grow here. The surrounding mountains are absolutely gorgeous, and while the conditions are extremely harsh, cold, and the wind often howls down the valley, floating the river here ranks highest of any river in the province this time of the year for the white peaks and herds of elk we often see while floating. Sure, there's the odd bull trout that shows, but the reason for the float is to appreciate what's here, not our use and conquering of it.
I will never understand the blatant ignoring of simple rules like "don't drive your atv here because we're trying to conserve what's here". Driving a skidoo or atv right past the sign, that's just mindboggling. Yet, it is so typically human, the mindset of conquer, use, and move on so prevalent. Especially here in Alberta where we have so much money, but so few brains attached to pro-active forethought of our future. Do we have to drive our off road units everywhere in the province, especially in the 1% of the landbase under Alberta gov jurisdiction that is actually protected?
