Since plants are usually quite sensitive to their natural living conditions, the contamination of soil with harmful substances may lead many plants to die off. Moreover, forests are a natural habitat for many animals and plants which may become endangered if these forests are cut down.
Evolution of Land Plants. No discussion of the evolution of plants on land can be undertaken without a brief review of the timeline of the geological eras.
