irreversible‚ but when the clearing is minimal the effects can be reversed. The threat to the environment lies with the irreversible clearance and can destroy an entire ecosystem causing environmental threats‚ such as green house gas emissions‚ a rise in soil salinity‚ the destruction of natural habitats for animals‚ the decrease and even extinction in indigenous flora and fauna‚ as well as erosion. Extensive land clearing is a problem in Australia‚ New Zealand and Tasmania. History For the most part

Sinkholes are incredible destructive unpredictable natural disasters. Florida has many sinkhole occurrences‚ caused by its limestone soil weakening with dried up water pockets in it.

versus environmental deterioration also has created a debate. Some economists argue that the on-site impact of soil erosion and other degradative processes are not severe enough to warrant implementing any action plan at a national or an international level. Land managers (farmers)‚ they argue‚ should take care of the restorative inputs needed to enhance productivity. Agronomists and soil scientists‚ on the other hand‚ argue that land is a non-renewable resource at a human time-scale and some adverse

monsoon climate brings very heavy rain and snow‚ and soils are leached and heavy runoff results in soil erosion‚ snow melting results in soil erosion and a rapid increase in river discharge. Moreover some more reasons are because deforestation in head water areas due to increasing population in Nepal and Tibet. Trees cleared for fuel and grazing land ‚ less evaporation more runoff and faster soil corrosion‚ Rivers silt up due to increased soil erosion. This raises the river bed and reduces the capacity

This is one of the strong reasons of increasing soil salinity of coastal areas along the Bhavnagar Taluka. At some places in the study area it was also found that salinity is increasing not only because of natural causes but there is a big human intervention in it‚ the prohibition of which is necessary
