The correct answer is: d) All of the above
Eucalyptus trees are a type of fast-growing tree that is native to Australia. They are often planted in other parts of the world, including Punjab, India, for their commercial value. However, eucalyptus trees have been criticized for their high water consumption, slow growth rate, and low commercial value.
Eucalyptus trees are known for their high water consumption. They can take up to 10 times more water than native trees. This can lead to water shortages in areas where eucalyptus trees are planted.
Eucalyptus trees also have a slow growth rate. They can take up to 20 years to reach maturity. This makes them less profitable than other types of trees that can be harvested for timber or firewood.
Finally, eucalyptus trees have a low commercial value. They are not used for many products, and they are not as popular as other types of trees for landscaping.
For these reasons, the presence of eucalyptus trees in Punjab is often debated. Some people believe that they are a valuable resource, while others believe that they are a threat to the environment.
