Document Summary
We are doing things to soils that, in the long run, are not sustainable. 6000 times more expensive for off-site costs than on-site costs. People who are downstream have the problem, not the land owner subsidize them to minimize their impacts (pay them to use no tillage) We want the on-site people to keep doing what they"re doing (cid:523)ex: agriculture(cid:524), so we. We took all the animals and killed them so they can"t leave their waste behind to. )f we don"t deal with these issues, we will fuck ourselves over. erosion on the exam. Don"t write an essay though, just key relationships, figures, and create areas where grass can grow. There will be a big, open-ended question about soil points. Relationship between rainfall and soil loss from erosion. Where there is rain, there is vegetation that protects the soil from erosion. There is more erosion in grassland and less in forests because of interception (canopy from tree leaves)
