HAVE HUMANS HARMED THE EARTH OR MADE IT A BETTER PLACE?

The Earth 'our home' is a planet with a wide range of inhabitants. This diversity helps to maintain the balance of the life cycle on the Earth. We humans have a key role to play in maintaining this ecological system. But today, even amidst the huge cry from environmentalists, we seldom recognize the importance of the environment. Some of the changes on the Earth like deforestation are a result of industrial and automobile emissions and nuclear activities. They bear testimony to our negligence towards the environment.
Right from our school education we have been taught about the key role played by the forests in maintaining the ecological balance. Forests attribute to release of oxygen and absorb the toxic carbon dioxide exhaled by the humans. Thus the forests act as the natural recycling agents balancing the life on this planet. Deforestation has been taking place for many reasons like manufacture of paper from wood pulp and timber, and for inhabitation by humans. If this trend continues there is no doubt that in the years to come the Earth will become a dry planet.
If deforestation is plundering the gift of God, the pollution of environment by automobile and nuclear emissions is a man made menace. Metropolitan cities have been so congested that we are getting used to everyday traffic snarls. Though there has been a worldwide awareness in controlling the automobile emissions in terms of imposing the emission norms on the automobile manufacturers, there is still much left to be done. One step could be to impose the law, to get the vehicle owners check their vehicles for emission norms, once in six months and obtain a valid test certificate.
No one can deny the fact that nuclear emissions are more vulnerable to damage the environment than any thing else. But we are always at the threat of a nuke war, despite the strong efforts of the international organizations like UN. It is a pity that most of the governing nations of the Un are the major threats with nuclear weapons.
Not but not least, the knowledge and the responsibility of safeguarding the environment is seldom seen in the individuals. The fact that all of us have been taught about the importance of environment in our education system makes no difference. The governments should organize more effective campaigns to educate everyone across all demographic levels. Only a socially responsible citizen can make a difference towards the environment our descendents have to live in.
Though I feel that with all above references, we humans damage the earth, I feel that I have dealt superficially some of the solutions that help to make the earth a better place to live. Let us hope that in the coming years future generations become socially responsible in safeguarding the earth. After all, we have just one planet (right now!) to live in.

HAVE HUMANS HARMED THE EARTH OR MADE IT A BETTER PLACE?

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, human activity is damaging the Earth. There are many reasons for my perspective as follows.
First, human activity causes many kinds of animals and plants to disappear. Today many species of living beings died out or near died out. We only can see some animals in the zoo because in nature they have disappeared. Human beings have been using their brains and machines to remake nature for many thousands of years. We use the habitats of animals and plants. We eat their food and eat them as food. Because animals and plants cannot grow fast to satisfy human beings, we cannot see them today. If some animals are dangerous to us, we kill them with our weapons. If meats of some animals are delicious, we eat them. No animals can copy with human being.
Secondly, human beings cause pollution to the Earth. I remember when I was young; I drank water from the river and stream. Today we can only drink bottled water bought from the market, because natural water is polluted by human activities. Air in some countries is polluted very badly, so many people died of lung cancer. I saw some reports that says in London people could not see each other clearly in a short distance in the morning because of much smoke and fog.
Finally, population on the Earth exacerbate rapidly. Human beings need more food and shelters because of increased population. More food and houses mean more needs from the Earth. Thus people need to cut more trees to build houses. People need to plant more vegetables and feed more cattle, so they demand more lands from the nature. Thus people are destroying more forests and natural lands. The living beings are losing their habitats.
Take into account of all factors I think the earth is being harmed by human activity. Today we cannot breathe fresh air and drink natural water. We have not enough places to live. We worry about our health because of pollution.

HAVE HUMANS HARMED THE EARTH OR MADE IT A BETTER PLACE?

When it comes to what human activity made the Earth, tradition has human activity that damaged the Earth. Nevertheless, although human activity has caused some damage to the earth, our Earth has certainly been turned into a much more beautiful world than it was centuries ago.
First of all, due to the development of human productivity made possible by science and technology, we now enjoy living conditions that our ancestors could never dreamed of. Nowadays, we use machine to plant crops, use synthetic fodder to feed livestock, use water conservancy project to generate electric power and so on. In term of substantive level, no other reasons in my decision is more crucial than the one above.
Furthermore, the use of machines has greatly improved our working conditions, enabling us to enjoy more leisure and entertainment. Tape recorder's invention serves as a typical example. They are small and have well sound quality. We can take it everywhere with us and the tape recorder has a valuable argument that it enabled me to listen to my favorite music wherever I want in a variety of different formats.
Of course, it should be admitted that human activity has resulted in the environmental crisis, which I believe we could overcome with the help of science and technology. The majority holds the opinion that human activity carries lots of pollution, which made the air quality worse, and endangered species increases everyday. On the surface, these seem to be terrible. However, people are taking a fresh look at it that they can be improved sooner because of science and technology development.
In short, human activity makes the Earth develop. It is difficult to imagine how the world will be without human activity. Similarly, a person who does not use machine in peacetime that cannot get anything done. Therefore, after pondering this question on many occasions, I believe that human activity makes the Earth better and beautiful and a great place to live!

HAVE HUMANS 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.

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.
