Effect on us and the Earth

The use of this tree for us humans are basically for attraction. If we want a specific place to be easily recognize or easily called beautiful, we plant a cherry blossom. because of it's colour and popularity among us we come to find cherry blossoms attractive.
This would be a positive for us because it plays a role of being an ornament display outside homes.

It is also good for the environment because cherry blossom or also known as Yoshino cherry are subject to witches broom. If branches bloom are infected and leaf out earlier then the brooms are pruned out, to help control the disease. Basically it removes and control the disease from not spreading even more, it lessens the diseases in the environment. So this is also positive to us.
