Read the passage given below and answer the questions that follow: 10 x 1 = 10
Forests are an important part of civilization. They not only form a considerable portion of the national wealth of a country, but also play an important role in maintaining the environmental balance. Indiscriminate felling of trees to enhance city areas is a threat to our civilization. We often forget that a peaceful, sensitive and wellbalanced co-existence of man-made civilization and natural flora and fauna is absolutely important for human existence on the earth. We forget that deforestation for the urbanization project led to the destruction of past civilizations such as Mohenjo-Daro. Indiscriminate felling of trees not only leaves our planet with fewer trees but also threatens the wildlife of the region. Forests and trees have an enormous impact on the climate as they are instrumental in drawing rain to the earth. Deforestation has resulted radical changes in our climate. The overall temperature of the planet is increasing at an alarming rate. The duration of seasons is fluctuating all over the world. The rate of rainfall is decreasing day by day. The ice-caps at the Poles are melting as a result. The amount of cultivable land is reducing as a result of deforestation and less rainfall. The future of this planet is in trouble unless immediate attention is paid to this danger.
Thousands of species of plants and animals are fast disappearing from the face of our earth as a result of human callousness. Forests in the mountains play an important role in preventing erosion and landslides. Felling of trees in the hilly regions endangers the lives of people that live there. However, the silver lining is that several people are becoming aware of this danger. A number of environment activist groups are undertaking a campaign to save forests.
Afforestation and preservation of wildlife can be an answer to this environmental crisis. By planting new trees, we can slowly restore the environmental balance that was disturbed by deforestation. Though, the process is long term, yet it is sure to save our planet from extinction. A thorough mass awareness against deforestation and preservation of wildlife is the call of the hour. It is only through mass sensitization and participation that this aim can be realized in future.
