SOCIAL NETWORK IMPACT ON YOUTH
One of the biggest problems facing the world today is global warming. Many scientists believe that our production of carbon dioxide and other greenhouse gases is having a heating effect on the atmosphere, and this could be very dangerous for human life. This essay will examine the problem of global warming and suggest some ways of solving the problem.
Many problems could result from global warming. One of the biggest problems is rising sea level. This could result in the flooding of low lying coastal areas and cities, such as Egypt, the Netherlands, and Bangladesh. Some countries might even disappear completely! Another problem caused by global warming is changes in weather patterns. Many areas of the world are experiencing increased hurricanes, floods, and other unusual weather. A third problem associated with global warming is the effect on animals. Fish populations could be affected, while some insects which spread disease might become more common.
There are several things we can do to solve the problem of global warming. One solution is to stop producing C02. We can do this by switching from oil, coal and gas to renewable energy. Another solution is to plant more trees. Trees absorb carbon dioxide and produce oxygen, which is not a greenhouse gas. A third solution is to use less energy and to recycle more products. Generating electricity is one of the main sources of carbon dioxide. If we use less electricity, we will produce less C02.
In conclusion, if we make small changes now in the way we live, we can avoid huge changes in the future. Scientists, governments and individuals must work together to overcome this threat.
Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. The earth is getting warmer. The changes are small, so far, but they are expected to grow and speed up. Within the next fifty to one hundred years, the earth may be hotter than it has been in the past million years. As oceans warm and glaciers melt, land and cities along coasts may be flooded. Heat and drought may cause forests to die and food crops to fail. Global warming will affect weather everywhere, plants and animals everywhere, people everywhere; humans are warming the earth's atmosphere by burning fuels, cutting down forest, and by taking part in other activities that release certain heat trapping gases into the air.
One major cause of global warming is the use of fossil fuels. Fossil fuels like coal, oil, and natural gas that were formed from the remains of plant material deposited during the earth's carboniferous period. We have known for only a few thousand years that coal, oil, and natural gas can be burned to provide energy. It was not until the mid-1800s, however, that we began to burn very large quantities of these fossil fuels. The worldwide consumption of fossil fuel has increased dramatically. The world now burns at least five billion tons of fossil fuel each year. As this carbon dioxide from burning fossil fuels enters the atmosphere, some of it is taken up by photosynthesizing plants, and the oceans absorb some. But because we are burning so much fossil fuel at such a rapid rate, we are putting carbon dioxide into the atmosphere much faster than these natural processes are taking it out. There is no longer a balance between the amount of carbon dioxide being added to the air and the amount of carbon dioxide being removed. As a result, the concentration of carbon dioxide in the air is steadily increasing.
Unfortunately, burning fossil fuels is not the only thing that we humans are
Essay about climate changes
Nowadays climate change is the biggest problem of the human being. It is already happening and represents one of the greatest environmental, social and economic threats facing the planet.
The warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level. The Earth’s average surface temperature has risen by 0.76° C since 1850. Most of the warming that has occurred over the last 50 years is very likely to have been caused by human activities. In its Fourth Assessment Report projects that, without further action to reduce greenhouse gas emissions, the global average surface temperature is likely to rise by a further 1.8-4.0°C this century, and by up to 6.4°C in the worst case scenario. Even the lower end of this range would take the temperature increase since pre-industrial times above 2°C – the threshold beyond which irreversible and possibly catastrophic changes become far more likely.
The climate can affect every person and our health directly through increases in temperature. Such increases may lead to more extreme heat waves during the summer while producing less extreme cold spells during the winter. Particular segments of the population such as those with heart problems, asthma, the elderly, and the very young can be especially vulnerable to extreme heat. There can be extreme floods and droughts, hurricanes.
Nowadays there are so many factories that exhale really destructive substances and pollute the air. We all know very well that air is something we can’t live without. When we breathe the polluted air, we can get seriously ill. Ground-level ozone can damage lung tissue, and is especially harmful for those with asthma and other chronic lung diseases. Sunlight and high temperatures, combined with other pollutants such as nitrogen oxides and volatile organic compounds, can cause the ground-level ozone to increase.We cannot escape from the polluted air-it’s everywhere, even in our homes and we are breathing it non-stop. This can cause cancer and other serious diseases.
Another huge problem is that the sea levels are rising worldwide. Also the expansion of ocean water is caused by warmer ocean temperatures.. Mountain glaciers and small ice caps are melting as well as Greenland’s Ice Sheet and the Antarctic Ice Sheet. The temperature is rising which means that ice is melting faster and faster.
However, these are not the only problems. Another issue are the greenhouse gasses. They are gasses which trap heat in the atmosphere. Some greenhouse gases such as carbon dioxide occur naturally by natural processes and other are created and emitted solely through human activities. For example carbon dioxide is entering the atmosphere because of human activities like burning of fossil fuels (oil, natural gas, and coal). All vehicles exhale too much damaging substances. People have been trying to reduce them but the problem is still topical and I think we have to do something like ride a bike not a car to work or school, we should take the shortest route possible, and plan our drive so that we will not backtrack or travel out of our way.We also may choose a clean-burning fuel, which reduces ozone-forming pollutants and buy a car that produces fewer emissions or runs using an alternative fuel.The taxes of cars should be higher and most of the people will prefer to use the public transport and we will no longer have traffic jams and we will reduce the damaging emissions.
As a conclusion, I think that when it can not do both, The UN should prioritize combating climate change over reducing poverty. Of course, poverty is a big issue, which needs a solution but have you ever asked yourself why the poor countries like Bangladesh, Gambia, Zambia are poor and why so many people die? It’s because the climate doesn’t allow them to grow food and they can’t afford to buy it from other countries. The climate is a very important thing and if we don’t stop the changes soon, more and more plants and trees are going to die, we won’t have enough food and then not only will the third world countries suffer from hunger but so will the whole world. I think it is better to first stop the changes in climate and then gradually reduce the hunger in the poor countries. Because if we stop the changes, we are going to be healthier and everything around us will be cleaner and it will be how it actually should be. I believe harmony between nature and human beings will return.
SOCIAL NETWORK IMPACT ON YOUTH
INTRODUCTION
Online social media have gained astounding worldwide growth and popularity which has led to attracting attention from variety of researchers globally. Although with time all generations have come to embrace the changes social network has brought about, teenagers and young adults are the most fanatic users of these sites. According to various research studies in the field of online social networks, it has been revealed that these sites are impacting the lives of the youth greatly. When using these sites such as Twitter, Facebook or MySpace, there are both positive and negative effects on the youth.
POSITIVE IMPACTS
It is inevitable to ignore the fact that nowadays social network plays an essential role in teenagers’ lives. Most youths are spending at least an hour in these popular social media sites. Generally, 1 out of 7 minutes which are spent online by most of those who can access internet is spent on Facebook according to Shea Bennett. One may ask how spending all that time on the social media sites may have a positive impact on them. Well, social media helps the youth and any other user updated with what is happening around the world, help the teenagers stay connected and interact with each other even if they are many miles apart. This strengthens their relationship even if they finished school and moved to different locations they stay connected and update one another.
In addition, social media sites have provided a platform whereby the youth can create groups and pages based on their common discipline and end up building connections and opportunities for their respective careers by updating various topics to discuss. Youth who have been interviewed they say that social media has become their lifestyle and it makes their lives easier and efficient.
NEGATIVE IMPACTS
While on one hand social network sites seems to bring people together and connected on the other hand it creates social isolation in regard to BBC News report. As the youth tend to spend many hours on these sites, they rarely have face-to-face interaction. According various studies, scientists’ evaluation determined that social isolation can lead to a host of emotional, psychological, physical and mental problems which include anxiety, depression and somatic complaints among many others.
Other negative effects of social networking various people suggested included encouraging poor spelling and grammar, exposing underage to online predators, allowing spread of misinformation that is perceived as fact, decreasing productivity as those who are supposed to be working spend time in the sites to chat, provide a perfect platform for cyber bullying and providing details that increase risks of identity theft.
CONCLUSION
