Where have all the, mountains gone?

God wonderfully created everything. All of us benefited the bounty of His creations. There were lofty mountains which are perfectly shaped that no one can ever tell how these were formed. The canopy of varieties of trees shaded its surface. Green grasses and herbs covered its foot. These splendid mountains became the source of human's everyday needs; it provided shelter for wildlife; provided the air we breath;and even provided food for all living creatures like birds, animals, insects, and us the human. Unfortunately, we rarely find these things nowadays.
Where have all the mountains gone? People destroyed and destructed it little by little. Mountains are all flattened. Trees were replaced with skyscrapers, huge plants and factories, buildings, long bridges, and satellite towers. Why is it that to be progressive is to face a dim future? We are completely influenced by the advancing technology yet suffering from all the calamities. It is a progress which leads us into nothingness.
