Abstract:
Now a day, pollution has become the biggest threat for the survival of the biological species.
There are different types of pollution e.g. air, water, soil, noise and mental pollution. Ornamental
plants instead of adding aesthetic values also improve environment by different ways like
Temperature regulation, oxygen production, regulate rainfall and check spread of desert, carbon
sequestration, control urban glare and reflection, control water and soil erosion, reduce impact of
weather through windbreaks, air, water and noise pollution. Soil salinity is also a major
environmental issue affecting livelihood of many due to the effects on agricultural productivity
and environmental quality. In this review, I tried to compile the work of different authors from
1971 to 2022.
