The Problems that Our World Faces Today
The earth is considered as one of the most beautiful planets in the universe. It is the only planet in our galaxy that has enough water to support life. Unfortunately our planet is suffering due to many problems which should be solved before it is too late. The major problems that are facing our world today are population, pollution and animal extinction. One of the problems facing our world is population. It began about ten thousand years ago when the humans settled and began farming. The farming provides more food for the people thus making the population grow. Now we are about 6 billion in population and in a few years we will be around 10 to 11 billion. Therefore, our population will

Pollution is another major factor that is threatening our world today. One example of pollution is nitrogen. Humans are adding about 130 to 150 million tons over the 90 to 150 tons that are produced by the nitrogen cycle. This excess in nitrogen causes coastal waters and estuaries to grow toxic algae, killing the fish and trapping the solar heat in the air. Another example of pollution is methane. Methane is produced by gases released by cows, termite mounds or by the bottom of rice paddy. If found in the air methane is very poisonous. By raising more cattle, cutting more tropical forests, thus increasing the amount of termites, and by growing more rice, the methane concentration in the air is almost twice as higher as it was 160,000 years ago. Smoke is another pollution factor. Smoke that is produced by cars contains carbon dioxide (CO2). This carbon dioxide in the air causes global warming, which results in the green house effect and climate changes. Satellite studies show that perhaps we will increase the temperature by 3.6 degrees by the year 2001. The warmer the weather the more water it can hold, the higher the precipitation will be. The higher the precipitation the more clouds, the more rain, and the more snow there will be. This will result in more storms and floods. Studies by Thomas Karl of the National Oceanic and Atmospheric Administration showed that the total winter precipitation in the US has increased to about 10% since
Population Growth is an issue that exists in today’s world that needs to be confronted before it becomes out of hand. The population itself has reached overwhelming numbers making it a problem that could turn to be dangerous. The amount of humans that the earth can support or the carrying capacity is slowly rising but at a much slower rate than the population growth rate. The increasing growth rate has its negative effects environmentally, agriculturally, socially, and economically and also has its positive effects nationally, and economically. The government is brainstorming and trying to come up with ways to decrease
The world population of 7.2 billion in mid-2013 is projected to increase by almost one billion people within the next twelve years. It is projected to reach 8.1 billion in 2025, and to further increase to 9.6 billion in 2050 and 10.9 billion by 2100. This assumes a decline of fertility for countries where large families are still prevalent as well as a slight increase of fertility in several countries with fewer than two children per woman on average.
The article by Dennis Dimick brings up some very good points about the increasing population. He states that with our current population of 7 billion people, we currently do not have enough food to eat. With the population increasing day-by-day, we will face more shortage in the future. He also brings up the issue of natural resources. We are currently using so much natural resources that we will run out very soon. The use of natural resources tend to increase with increase in social standing (wealth).
As the human race continues to grow older the population starts to grow. Population growth is a change in the size of a population over time, depending on the balance of births and deaths over a period of time. For the world, population grows when the amount of births exceeds the amount of deaths. As shown in figure 1, the world’s population grew very slowly until about 1750 that is when the population growth started to increase rapidly. Figure 2 shows the growth of the global population from 1950 onwards, it also shows the projected population growth up to 2050. The global population is estimated to rise to approximately 9 billion people by 2050.
Over population is an extremely serious problem facing the world today. According to an article from Newsweek in Oct. 2009 called “Where do babies come from?”, today’s world population has reached over 6.6 billion people. Also the article mentioned that in 2009 57.4% of all new born babies who were born this year came from Asia alone. This is an issue because over population can lead to hasty consumption of resources. China who has one of the largest population in the world with over 1.3 billion people, has taken a stance against over population.
In the world there is over 300,000 births per day. If the world continues like this, then in 2030 we might be up to over 30 billion people. If the world’s population got so high we would not have enough geography, space for those lives. Jobs, resources, crime, diseases and much more things would be in jeopardy!
The human population is growing rapidly, and Earth doesn't have enough space for it. In 1967, Earth had a population of 3 billion, and only about 50 years later, that number had doubled into 7 billion. There are many reasons why our population is increasing so fast, in so little time, but I'll only go over two. The first, and foremost the most recognised reason, is the birth to death rate ratio. Every minute there is almost twice as many births then there are deaths; 200 births to 100 deaths. There is an estimated 350,000 born every day with only 150,000 deaths, making there 4 births every second and 2 deaths every second. Overwhelming right? Well the second reason which goes hand in hand with the birth to death rate, is, over the last few hundred years, we have become more intelligent, and more self aware. Our knowledge on medicine has grown like no other, and our life expectancy has grown with it. With many more factors modifying our population rate, these two show it best. We are living longer and having more babies, but soon we’ll need to stop.
growth rate in the United States is approximately 2.2%. This means by 2050 the population could reach 438 million people (“World Bank Group”) Many citizens do not see any danger of the population rise in the United States. Unawareness might be the biggest factor in why they believe this; however, overpopulation can destroy the environment, including food and water sources, while also raising unemployment rates and the risk of disease.
In the world today we have became to known of the upcoming problem;its not only been a problem in the U.S but other counties as well. Today’s population consist of 7,362,302,944 people world wide.Although, growing in population is consistently is a bad thing but it can be a good thing.
The world is growing at an extremely fast rate which will lead to an unhealthy place for people to live in. If current trends persist, there will be 2.5 billion more people on the planet by mid-century. It will be difficult to feed that many people. There are many problems with population growth and the laws associated with it, but there are also ways to counteract these issues. By spreading awareness, creating laws, and more family planning we can prevent population from growing out of control.
Automobile pollution increases global warming and causes severe damage to environmental and public health. Carbon dioxide emissions from automobile engines are the leading cause of global warming (Ridlington & Madsen, 2014). Temperatures across the country are experiencing a significant increase causing ice to melt and a rise in sea level. This results in frequent coastal flooding that consequently comes with devastating outcomes such as high
As opposed to Malthus and Ehrlich's time, today's population is not increasing at a geometrical rate. In fact, the rate at which the world population increases is on the decline (See Figure 1.1 and Figure 1.2). The UN predicts that by the year 2050 the rate of population increase will near zero and our total population will be somewhere between 7.3 billion and 10.7 billion people, with the most likely population being 8.9 billion (Lederer).
It is predicted by the year 2050 the world's population will have increased to over 9 billion people. (International...) If this prediction comes true the world will become overpopulated and cause problems like famine, the world already struggles with feeding the amount of people alive today. A second problem is housing, in underdeveloped countries there is already a struggle with giving people places to live, so companies clear land to build houses but that leads to habitat loss and animal loss. The third reason is disease, if a disease was started and spread when the world was overpopulated the disease could eliminate half of the human population.
I think most people can agree that if we all change our mindset and governments work together to solve the problem, there can be drastic improvements. As stated from greenliving.com, “An increase in population size makes excessive demands on natural resources, and increases the demand on agriculture and livestock.” Overall, there are many negative impacts associated with population explosion. Some environmentalists believe that the human race will reach its carrying capacity relatively soon and our population will plummet. I beg to differ because I think that humans will find a way to solve the population problem before disasters arrive. The most efficient and easy way to solve the problem is very controversial. In The Tragedy of the
There are more than seven billion people on Earth now, and about one in eight of us don’t have enough food to eat. So, with a projected nine billion people by the year 2050, how many people can the Earth support while maintaining a healthy population? Population changes are due to the relationship between births and deaths. If the number of births equals the number of deaths then the world’s population will remain the same, but if births exceed deaths, population growth will occur. Early in history, population was slowly growing because of high death rates related to wars, famines, and poor medical services. With advances in
