Which situation would most directly affect future generations naturally produced by a maple tree?

Ultraviolet radiation changes affect future generation naturally by DNA sequence within the gametes of some flowers of the tree. A maple tree is referred to as deciduous hardwood tree. It is the same member of sycamore or Acer.
Acer is not exclusive but generally of an ornamental nature. Cutting of trees affects nature due to deforestation for a period of time when desertification takes place and soil then loses its fertility and becomes loose.

Only algae, oak trees, and bermuda grass produce atp by photosynthesis i am almost positive
