Population Throughout most of human history, the population of humans on earth has been kept in check by environmental factors. With humans relying completely on the resources near to them, if a population began to grow too large it would be held back by a need for resources such as food and water. Once a civilisation grew large enough to have the food produced outside of larger cities and sold to the people in the cities, Diseases were the main factor holding population in check. However in the early 1800’s, the population of the world increased drastically due to advances in medicine that greatly increases the expected lifespan as well as reducing the infant death rate. In today’s world, the population is growing at a rate that is devastating to the earth. The United Nations has projected a population of nine billion people by 2050. In order to see how the effects of this growth can be reduced and reversed, one must examine the impact it will have on basic needs such as food, water, and energy.
One major need for the survival of the human race is water. Every day, more than one billion people on earth lack access to safe, clean, drinking water. Though the majority of the earth of covered in water, less than three percent of it is fresh water. Much of the freshwater on earth is frozen in the polar ice caps or in glaciers. Due to this, less than one percent of the total water on earth is fresh and available for drinking. At this point in time over half of this water is
It is terrifying to realize that the human population on Earth has reached over 7.3 billion people. This astonishing and constantly increasing amount of people threatens our planet’s limited resources. It is times like these that make me nostalgic for the feudal ages, where large populations of people were decimated by illnesses such as the plague. The advances in modern medicine today, while extremely impressive, are ultimately extremely detrimental to the human population as a whole because they surprisingly help prevent people from dying. How dare they! Humans are starting to get a better quality of life due to the many advances in medical technology and knowledge, but at what cost? People won’t die! The question is, why should we, as a society, try to prevent people from dying when it’s inevitable? In the animal kingdom, it’s everyone for themselves, or survival of the fittest. If people are too weak to fight off an illness, or too stupid to find a way to stay alive, then they should die.
the population is said to reach 9 billion by 2050. The overpopulation of humans is causing destructive impacts on the environment and a high demand for resources. One destructive impact would be climate change because of the exceeding rate of humans, causing pollution in the air. While the Earth is having a tough time sustaining particular resources, the high demand causes the earth to force to get its nonrenewable resources. Overpopulation can lead to dangerous impacts of pollution, depleted resources, habitat loss, etc. Overpopulation is a controversial topic. While there are those who are not paying attention to its effects, the world is displaying its resources will soon disappear due to the depletion of nonrenewable resources such as water, oil, and soil. Addressing the problems and concerns of overpopulation now, can help save the lives of individuals in the future, LITERALLY!
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
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
Water may be a renewable resource, but the world’s supply of drinkable fresh water is being consumed more rapidly than ever before, and most importantly, more rapidly than it can be replenished. Only 2.5% of water on Earth is fresh
Water is all around us. This substance is of high importance to every living thing which is on planet earth. As much as we consider water to be life and the most important substance, still we don’t seem to appreciate it very much, as it is being wasted in such great amounts. Everyone believes that water will always be around but not taking into account that the majority of the water on planet earth are not for human consumption. Human beings can only survive on consuming fresh water. The percentage of
Human population growth is becoming a huge issue in our world today. The population is increasing rapidly. The reason that it is becoming a concern is because it has affected the economic, environmental, and social aspects of our world. In the film Frontline: Heat, we can see how there might not be a future for our planet unless we are able to reduce the emissions and make our world a safe place. Not only for the present but also for future generations so that they are able to live long and healthy lives.
Water is a fundamental resource necessary for all life on Earth. Humanity would be extinct without it. People think there is an unlimited supply of water, however there is not. The overuse of water is a problem that needs to be stopped. Society needs to learn to live in a more sustainable way. If humanity continues to overuse Earth’s natural resources the way it does today, the Earth will run dry. To prevent the depletion of water, people need to be aware of their impact on the environment and live sustainably. By controlling the population, limiting fossil fuel usage, and stopping greed, the depletion of water can be prevented.
The water crisis in the world is increasing, and it will continue to increase if something is not done. Water makes up approximately seventy-one percent of Earth’s surface. This does not include the water underground. Everyday water is being taken more than it is being put in, and people have a large role in this. Climate change, the number of people in the world, and water wasted is among the uppermost causes of the water crisis. It is simple, if you do not have water, you will eventually die. The water crisis is a health crisis for everyone globally.
As we are all aware, water is essential to life on earth. It is a common need that plants, animals and humans share. In developed countries we are often consumed with items we think we need, such as clothing or new vehicles. In fact, those may not actually be needs, but are considered wants. Water is essential to survival, but somehow people don't have access to it worldwide.
This increase of the human population is staggering, and the effect it will have on Earth is devastating. Questions will start to come up more frequently regarding the global food supplies, pressures on the environment, and the energy resources.
Water issues are big concern for every living thing on the planet. As the worlds population grows and the demand of products increase, industries are growing too. This demand on the worlds recourses especially water is becoming an issue. Around two percent of the worlds water is drinkable with much being locked up in glaciers. Moving water to places in need is a common practice, but this dose not make more drinking water. While salt water is easily accessible we can not consume it. The water must be processed with the salt being removed.
The expansion and development in all of the earth’s climate zones and habitats, as well as modern agriculture’s ability to grow more food for each unit of farmed land, play an important role in the population growth. Socioeconomic factors such as, healthcare, culture, family structure, marriage and social status also influences population growth, are contributors to population size increases through birth rate, as well as, decreases through the death rate. This imbalance of population equilibrium is a result of improved sanitation and health care, and the development of antibiotics and vaccines for the control of infectious diseases ultimately resulting in population death rates dropping.
Water covers 70% of our planet, and it is easy to think that it will always be plentiful. However, freshwater, what we drink, bathe in, irrigate our farm fields with makes up only 3% of the world’s water, and two-thirds of that is stored in frozen glaciers or unavailable for our use. Many of the water systems that keep ecosystems thriving and feed a growing human population have become stressed. Rivers, lakes and aquifers are drying up or becoming too polluted to use. Already, 80 countries suffer from water shortages that threaten health and economies while 40 percent of the world—more than 2 billion people—does not have access to clean water or sanitation
By the year 2025 it is predicted that, “1800 million people will be living in countries or regions with absolute water scarcity and that two-thirds of the world population could be under stress conditions caused by water scarcity”(IFAD). This data suggests an imminent and terrifying reality, earth is slowly running out of drinkable fresh water. This reality will most likely cause wars, starvation, and death for water is vital for human life with 20 to 50 liters needed daily to sustain basic human functions (IFAD). Unless we find a solution to this international human crisis, life as we know it will not be sustainable. Fortunately, scientists across the globe have made its their mission to prevent this crisis from occurring through
