Ways which you can make million through forest management(cutting and planting of trees).

A forest is a large area dominated by trees . [1] Hundreds of more
precise definitions of forest are used throughout the world,

incorporating factors such as tree density, tree height, land use,
legal standing and ecological function. [2][3][4] According to the
widely used [5][6] Food and Agriculture Organization definition,
forests covered four billion hectares (15 million square miles) or
approximately 30 percent of the world's land area in 2006. [4]
Forests are the dominant terrestrial ecosystem of Earth, and are
distributed across the globe. [7] Forests account for 75% of the
gross primary productivity of the Earth's biosphere , and contain
80% of the Earth's plant biomass. [7]
Forests at different latitudes and elevations form distinctly
different ecozones : boreal forests near the poles, tropical forests
near the equator and temperate forests at mid-latitudes. Higher
elevation areas tend to support forests similar to those at higher
latitudes, and amount of precipitation also affects forest
composition.
Human society and forests influence each other in both positive
and negative ways. [8] Forests provide ecosystem services to
humans and serve as tourist attractions. Forests can also affect
people's health. Human activities, including harvesting forest
resources, can negatively affect forest ecosystems.

Although forest is a term of common parlance, there is no
universally recognised precise definition, with more than 800
definitions of forest used around the world. [4] Although a forest
is usually defined by the presence of trees, under many definitions
an area completely lacking trees may still be considered a forest if
it grew trees in the past, will grow trees in the future, [9] or was
legally designated as a forest regardless of vegetation type. [10]
[11]

There are three broad categories of forest definitions in use:
administrative, land use , and land cover. [10] Administrative
definitions are based primarily upon the legal designations of
land, and commonly bear little relationship to the vegetation
growing on the land: land that is legally designated as a forest is
defined as a forest even if no trees are growing on it. [10] Land
use definitions are based upon the primary purpose that the land
serves. For example, a forest may be defined as any land that is
used primarily for production of timber. Under such a land use
definition, cleared roads or infrastructure within an area used for
forestry, or areas within the region that have been cleared by
harvesting, disease or fire are still considered forests even if they
contain no trees. Land cover definitions define forests based
upon the type and density of vegetation growing on the land.
Such definitions typically define a forest as an area growing trees
above some threshold. These thresholds are typically the number
of trees per area (density), the area of ground under the tree
canopy (canopy cover) or the section of land that is occupied by
the cross-section of tree trunks (basal area). [10] Under such land
cover definitions, and area of land only be defined as forest if it is
growing trees. Areas that fail to meet the land cover definition
may be still included under while immature trees are establishing
if they are expected to meet the definition at maturity. [10]
Under land use definitions, there is considerable variation on
where the cutoff points are between a forest, woodland , and
savanna . Under some definitions, forests require very high levels
of tree canopy cover, from 60% to 100%, [12] excluding savannas
and woodlands in which trees have a lower canopy cover . Other
definitions consider savannas to be a type of forest, and include
all areas with tree canopies over 10%. [9]
Some areas covered in trees are legally defined as agricultural
areas, e.g. Norway spruce plantations in Austrian forest law when
the trees are being grown as Christmas trees and below a certain
height.
