Some people believe that the Earth is being harmed (damaged) by human activity. Others feel that human activity makes the Earth a better place to live. What is your opinion?
We are now living in the information-based age, thank to the new technology, we can know the latest news over the world as we’ve never seen before. By that, we know that the Earth is changing too fast as time goes by, the Earth is being harmed by human activity.
First of all, the Earth is being harmed by I activities to satisfy human need. Hunting is spreading over the world, especially with rare animal, to satisfy the selfishness of many people. In the recent time, in Vietnam, some high-ranking official have been arrested and committed for trial because of illegal hunting. To meet the need of house building and house heating, many woods have been deforested, It make the protecting watersheds from soil erosion lessen that led to damage in agricultural crops. The profit from selling species in forest can’t afford what it make to the Earth because the greatest asset of tropical forests, however, comes from maintaining the Earth’s life-support systems.
People is destroying the Earth by expand their business activities as well, they put into work many new production line and machines all are gasoline-powered vehicles. Those machines can exhaust gases from its engine, the main effect that make the ozone-hole occur. This is the most important matter in environment today, because the ozone layer of the atmosphere protects life on earth from the full force of the sun's cancer-causing ultraviolet radiation, it is critically important. To understand more easily, in the mobile-industry only, you can know that there are about 12.8 million vehicles were produced in 2000, and each car can use 10 liters for 100km. It’s said that the fossil fuel in the Earth is just enough for human need in 30 years coming.
Above all, the most dangerous human activities that are destroying the Earth are wars. To be leaders in the world, many people can do anything even to force the other into war. Two great World Wars had taken so much life and had destroyed many parts of the Earth. On August 6, 1945, during World War II (1939-1945), the first atomic bomb to be used against an enemy position was dropped on the city by the United States Army. According to U.S., estimates 60,000 to 70,000 people were killed or missing as a result of the bomb and many more were made homeless. The blast also destroyed more than 10 sq km (4 sq mi) of the city, completely destroying 68 percent of Hiroshima's buildings; another 24 percent were damaged. Today, many terror activities are bursting, and nuclear weapon is one again to be most dangerous tool to destroy our Earth.
The Earth is considered a close friend of human life; It’s also the only thing to continue our life. The Earth is calling for help, so how we can do for this “friend” besides conservation? That also means our life will be longer and healthier.
