I would say all?- Purely because scientific research around climate change aids all of these things.
Hope that helps. :)
Naturalists would suggest that it is important to plant more trees so
that we can avoid the effects that come alongside deforestation such as
soil erosion and high levels of ozone. It is important not to
underestimate the positive effect that trees have on the environment, in
fact one tree can actually release enough oxygen to provide for two
people over the course of their lifetime.

Cancer is the uncontrolled growth of abnormal cells in the body. In the body, there are trillions of cells with various functions. These cells grow and divide to help the body function properly. Cells die when they become old or damaged, and new cells replace them.
Cancer develops when the body’s normal control mechanism stops working. Old cells do not die and cells grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor. Some cancers, such as leukemia, do not form tumors.
