Alfie, Tree Duplicator is such a fantastic and important invention. Well done for caring about our natural world and thinking up a way to keep forests dense and trees healthy and growing. So many trees are cut down to provide resources for our modern world so we do need to be making efforts to restore forests to their natural state. A machine to duplicate trees would be a really effective way to do this, and would ensure that we can repopulate natural woodland. Thanks for being environmentally conscientious Alfie, please send us another invention soon!
