Topic 29 Has human harmed the Earth or made it a better place?

People have learned how to turn wild natural areas to farm land, how to exploit minerals to adapt their needs, how to build roads and houses to expand their territories. People continuously improve their knowledge and develop technologies to improve their lives. It is undeniable that these activities of human beings make their lives better than ever before. Nevertheless, those activities also cause side-effects to the Earth because of pollution, deforestation, and exaggerated natural resource exploitation.

Nowadays, pollution becomes one of the most concerned problems. Because of the increasingly expanded factories, the industrialized areas, the burning of population etc, too much pollutant spills out everyday. Consequently, all of these things cause bad effect to the Earth. The purity of atmosphere is reduced seriously, the Earth is continuously warmed up, and ozone layer is holed.

Additionally, forest is asking for help in desperation. For last few decades, the forest areas have been reduced to 50 percent because of human deforestation. Green forestland of the Earth can be compared to the lungs of human. How healthy you are if their your lungs are trespassed. I am sure that you will get more difficult with aspiration; as a result, your health will be affect badly. From this example, we can infer that how serious problem our Earth has to face with. I wonder how long it can endure.

Researchers show that the natural means is limited, but today, they are exploited so increasingly to adapt infinite human needs that someday, all mineral can be ended up. Because of serious pollution, alarming deforestation and progressive mineral exploitation, the ecosystem becomes unbalance. Consequently a lot natural calamities happen each year such as flood, hurricanes. A lot wild living creatures are exposed to narrow place of shelter and lacking foods. For these reasons, the Earth will become unhealthy.

In conclusion, the human beings harm the Earth. Human beings as well as their dear planet, the Earth, have been badly suffered by what caused by humans themselves. I hope that humans are soon aware of those problems so that they can have suitable policies in order to not only improve their lives but also keep and maintain the Earth fresh and green.

Topic 29 Has human harmed the Earth or made it a better place?

Although the quality of life has improved over the past decades due to new technological advances but the damages made to the earth weigh more. Damages include increase in pollution and change in climatic patterns. Irreversible damage to earth can include depletion of natural resources.

As the technology advances more factories are built. These factories dispose waste material into natural water, which could be harmful to aquatic life. Emissions from the factories and automobiles pollute the air, which we breathe. Nuclear waste and radiation from power plants are harmful to our health.

There can be drastic changes in the climatic pattern due to the increase in the carbon dioxide released into the atmosphere, which is the main cause of global warming. Global warming would increase the temperature of earth and make it inhospitable. We are cutting more and more trees for furniture's, and wood. Trees purify the atmosphere by absorbing the carbon dioxide from the atmosphere and releasing the oxygen. Furthermore, the roots of tree hold the soil and prevent floods.

Resources of petroleum, oil, and minerals are not endless. There is shortage of water all over the world. Once depleted of these resources, our life would be difficult. Killing elephants for their teeth, and other species for their furs disrupt the food chain. For example killing of carnivorous animals would cause increase in the number of herbivores, which would consume more plants. We also depend on plants for food so there can be shortage of vegetables and cereals for us.

We should preserve the earth and respect all its valuable resources. Pollution and climatic changes can make earth inhospitable. Our future would not be good without sustainable development.
