Answer 2

Answer:

Three sentences on how we harm tree could be:

i) We cut entire trees, even gorging out the roots of the trees, thus forcing the life out of them, i.e. we kill the trees.

ii) Often we pluck all the flowers from a tree; which hampers sexual reproduction of  the trees.

iii) Using excess of pesticides, herbicides, weedicides, etc. harms the tree, by adding chemicals to the soil, which takes up by its roots, ultimately harming their system in the long run.
