Sun pollution would be the only one that does not apply.

Answer 2

The correct answers are :

Deforestation: The cutting of trees in large amount is called Deforestation. It is caused due to human impact.

Loss of species diversity: The selective breeding technique induces genetic depression and increases the chances of a loss of diversity of plant.

Water pollution: Water pollution can adversely affect the growth of the plant by changing the growing conditions of plant by increasing the acidity of water.

Soil pollution: The polluted soil will affect the growth of the plants and will affect the plant. This is also caused by the human interventions and increases the acidity of soil.

Air pollution: When air pollutants combine with water(rain) it forms acid rain and this affects the growth of the plant.
