Weegy: We can sustain rangeland productivity by controlling the number and distribution of livestock and by restoring degraded rangeland. [ ]


User: what happens to forests that are not replanted arter trees are cut







Weegy: clearcutting and global warming interact to exacerbate the effects of one another. Erosion caused by clearcutting results in increased run-off of rain earlier in the spring. [ At the same time, as the temperature has risen over the last several decades due to global warming, the snowpack has decreased in many recent years and has melted earlier in the spring than usual; in 2007, snowpack in the Sierra Nevada was less than a third of average. The 12-month period from May 2006 to May 2007 was the driest on record for California and Nevada, according to NOAA's National Climactic Data Center.6 Rising temperatures throughout the west will cause more prolonged droughts and wildfires, according to a report from the National Wildlife Federation. 7 As a result, the mountains of California are becoming less effective in playing their historic role of storing water from snow and rain until summer when the water is needed in the valleys. These changes result in forests that dry out earlier in the year, resulting in a significant increase in the number, intensity, and length of forest fires. Those fires then release more carbon into the atmosphere, increasing global warming, which in turn creates more fire danger. This feedback loop is difficult to stop. ]
