Some previous attempts have been unsuccessful, for instance toilet roll companies planted forests on grass plains which unfortunately...

• Was unpopular with customers as it increased toilet roll prices

• Caused albedo modification, resulting in greater absorption of isolation

• Encourage illegal logging, using fossil fuels

• Encourage cow populations to rapidly expand, releasing more methane
