People have been living on the Earth for thousands of years. Human activity influences the Earth. Some people believe that the Earth is being harmed by human activity. Others feel that human activity makes the Earth a better place to live. In my opinion, the earth is being damaged by human activity. There are many statements supporting my opinion.
Human activity has damaged natural environment and almost exausted natural resources. Modern industry needs more and more resources, including minerals, fuels and water. So we confront of the serious problems such as the lack of fuels and water. Ecological balance is damaged because factories occupy many places where animals and plants live. More and more buildings are constructed and forests become less and less. If we cannot recognize these problems and solve them soon, we would finally lose the environment suitable for our living.
An other serious problem is "the green-house effect." Human activity decreases forests and increases the usage of fuels so that the gas of carbon dioxide is output more and more and there are not enough plants to absorb it. The green-house effect is more obvious and more sensible these years. Due to the effect, icebergs in the south polar and north polar melt and the sea level becomes higher than before. I am worried about the cities nearby the sea and hope scientists find an effective method to eliminate the green-house effect.
Although we have advanced machines and our life seems more comfortable than before, we have less chances to approach natures and less spaces to act. The cities become bigger and if we want to have a picnic with our friends, we have to drive a long distance to find a natural place. In fact, the spaces of human activity are being damaged by the skyscrapers and factories.
From the above statements, we can conclude that human activity brings the Earth many damages. Fortunately people have recognized the point and I believe that the Earth will become a better place to live with our ceaseless efforts.
Nowadays our Earth faces a number of serious problems, such as the environment pollution, the increasing population, the fatal effects of nuclear weapons, and so on. So some people believe that the Earth is being harmed by human activity. But as far as I am concerned that human activity makes the Earth a better place to live and also makes some negative effects in this process. My arguments for this point are listed as follows.
Even though we face so many crisis, no one can deny that Earth are more suitable for human habitation. That is the result of the efforts of generations of people. If without that, we might also live in caves and eat the crude food just like wild animals. If that is true, we must haven’t time and energy to think over the problems of the Earth because we have to look for food and avoid becoming the food of other animals. At that state, whether the Earth were harmed is not important for human because some certain crisises can annihilate the total population, such as some infectious disease or the a change of climates.
It is inevitable to produce some positive aspect functions when human are struggle to improve the survive abilities and from the experiences of history we also have make great effort to resolve this kinds of problems. For example, most of people hope to limit the scope of nuclear weapons and the protection of environment is accept by almost every one. Most of problems are controlled by ourselves and some of them have the hope to be resolved in years. We are finding the balance between the development and the protection of our Earth. So it is unnecessary to deny the advancement of human.
For the reasons presented above, we admit that there are some problems in the process of the human development, but those problems are resolving and as a whole we make the Earth a better place to live. Human evolved in the mode of continuing to correct their mistakes and making a better progress.
The quality of human life has improved greatly over the past few centuries, but Earth is being harmed more and more by human activity. As we develop our technology, we demand more from our planet. Eventually, this will harm people as well.
Our planet gives us everything we need, but natural resources are not endless. Strip mining devastates whole regions, leaving bare and useless ground. Deforestation removes old growth trees that can't be replaced. Too much fishing may harm fish populations to the point where they can't recover. We are too careless in taking what we want without giving anything back.
There are more people than ever, living longer than ever. So is it any surprise that many areas suffer from too much development? Anyone living in or near a city has experienced "urban sprawl." There is a new shopping area on every corner and new houses, townhouses and apartments everywhere. Traffic gets worse and worse because planners can't keep up with growth. Keeping up with human demand is hard enough. Environmental concerns come in last.
With growth comes pollution. Companies and communities dump waste into water. Landfills are full of trash. Emissions from factories pollute the air. Barrels of industrial waste and worse, radioactive waste, have no safe place to go. If we're not careful, we can harm our planet beyond repair.
People need to respect the Earth and try to preserve it. If we don't, what kind of future will we have?
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 every day. 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 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.
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.
