World population 2008 In 2008, 6.7 billion people lived on earth. From this amount, 1.2 billion lives in developed countries while the majority which is 5.5 billion people lives in less developed countries. Approximately four out of ten pregnancies world wide are unwanted pregnancies. This means that almost half of the births that contributes to population growth human consumption of resource is unwanted. There is a tendency that the majority population of those who live in more developed countries tend to have longer life expectancy and lower birth rates. On the contrary those living in less developed countries show shorter life expectancy and higher birth rates In addition to that, in developed country, the average birth per female is 1.6 in developed countries, 3.2 in developing countries, and 4.7 in least developed countries. 4. Fishery in 2012 In 2012 more than 1.2 billion people on earth rely on fish as their primary source of protein ;52% of the fish stocks are fully exploited, 17% are over exploited and around 7% of fish stocks are depleting worldwide. Within the last 60 years the stocks of large fishes have dropped at a remarkable amount by 90% Fishermen uses the method of trawling to capture the shrimps. They will drag a strong and large fishing net which is approximately the size of four football pitch across the ocean floor. This method usually catches a lot of unwanted marine life, usually around 80-90% of the marine life caught are by catch. The massive amount of by catch over a period of time will lead to rapid depletion to a particular species For example the scientists recommended that 10,000 tones of blue fin tuna should be fished so that it would be sustainable and blue fin tuna would be able to reproduce at a steady rate. however, the EU and other fishing nations decided that they would set the limit at 29,500 tones. What is very horrifying and sad is that 61,000 tones of tuna was actually caught, almost six times more than the rate that they would be able to reproduce sustainably and has lead to a decline of the blue fin tuna's population. If the Current population of blue fin tuna is to be compared with when blue fin tunas were un fished, there would have been approximately 96.4% decline in its population. All Atlantic Blue Fin tuna is now extinct in the Black Sea. Tuna_decline_sized. Digital image. N.p., n.d. Web. 6 May 2014 5. Global Water consumption in 2013 There are 783 million people who are living without access to clean drinking water. Approximately 70% of the earth's surface is water. Of that 70%, 97.5% is salt water which we cannot make use of and there is only 2.5% of fresh water on earth. Of that 2.5% of fresh water, 70% are frozen in ice caps and more fresh water are trapped deep underground where it is impossible to access. This leaves humans and other living organisms dependent on fresh water with less than 1% which are accessible and can be used. This proves that there is a very limited and finite amount of fresh water on earth. At present, 70% of the accessible water is being used for agriculture, 20% for industry, and only 10% for domestic or personal use. Every year the demand for fresh water increases by 64 billion cubic meter which is an increasing trend which does not seem like it will be slowing down anytime soon. WF-consumption2. Digital image.

World population 2014 The current world population in 2014 is approximately 7.2 billion people on earth or to be more exact 7,211,239,210 people living on earth. The largest continent in the world in terms of population is still Asia and the country which currently holds the largest population is still china. It is estimated that for every seven second, someone is born. On the other hand, for every thirteen second, someone passes away. World_population. Digital image. N.p., n.d. Web. 6 May 2014 7. Oil consumption 2014 Currently 74,900,000 barrels of oil have already been pumped out of the earth and there are only 1,200,000,000,000 barrels of oil left. If we continue to consume oil at the same rate, the amount of oil left can only sustain us for forty more years. Machine which pumps oil The demand of oil globally continues to increase. Currently, the global oil consumption increases by 890,000 barrels daily. Approximately as of 2014 there are 1.09 million barrels of oil pumped per day Return Home Stock-footage-oil-pump-jack-in-a-field. Digital image. N.p., n.d. Web. 6 May 2014 8. World's population in 2025 It is predicted that the population in 2025 will be in the range of 7.9 to 8 billion people worldwide if the mortality and fertility rate continue its trend India and China will continue to be the worlds two most populated countries. It is predicted that each country will contain around 1.45 billion people each. There will not be a lot of change in terms of numbers for the developed countries because the majority of population growth occurs in developing and underdeveloped countries. The population growth may increase the risk of 25 million Europeans going into poverty 9. Human consumption of water in 2025 48 countries will face shortage for safe drinking water affecting up to 3 billion people 24 billion people will be living without fresh water 1.8 billion people will have to undergo absolute water scarcity. On top of that two thirds of the world's population will not have sufficient water to live a comfortable life; they will have to live under water-stressed conditions. The amount of water being pumped out of the earth will increase by 18% in developed countries and up to 50% in developing and under developed countries. The demand for water from the industry section will increase by 56% because there is a lot of industrial growth. The majority demand for water will be coming from the agricultural section. In 2025 economic growth is expected which increases the income for most individuals. With more income people would have the means to spend more money on different sectors of their life such as food. One kilogram of rice requires 3,500 liters of water to produce while one kilogram of beef requires 15,000 liters of water to produce. When the demand for the more 'healthy' food increases, more water will be needed during the production phase. 10. Fishery in 2030 In this year more than 3/4 of the ocean's fish stocks will have either been overfished, depleted, or over exploited. This is why the amount of fish farms are increasing even though it is neither good towards the environment nor fishes. It is predicted that 60% or more of the world's fish will be coming from fish farms. In 2006 fish farms raised nearly 70 million tons of seafood which converts into approximately 80 billion dollars. In this year, 2030; it is expected that there will be a 70% more yield. Human annual consumption of fish will rise to around 150-160 million tones which for a average person, it is 19-20 kg.

Oil Consumption in 2030 Crude oil will still remain as the main energy source in this year and the demand for oil globally could reach 106 million barrels per day. It is predicted that there will be enough oil to produce approximately 99 to 110 million barrels per day. A price for a barrel of oil will be at least 113 dollars Because of the traditional fuels such as oil running out people are investing up to 17 trillion dollars on renewable energy in 2030. However sustainable energy such as, tidal, solar, and biomass combined will still only account for 4% of the world's energy source. Saupload_2h3csab. Digital image. N.p., n.d. Web. 6 May 2014 12. Fishery in 2048 It is predicted that if the current situation does not improve and humans continue to fish with the same rate and method, the stocks of all fish caught as food will most likely collapse which means that there may be no more seafood. The ocean's ecosystem worldwide is most likely expected to breakdown If the ocean is damaged it will result in harmful algae blooms, decrease in oxygen levels, and ocean flooding.

Human Consumption of water in 2050 Water can be a limitation to an economic growth because it is the essential core to industry yet we are still using it at a tremendous unsustainable amount. It is predicted that 45% of the total GDP which is around 63 trillion dollars will be at risk due to water stressed. The numbers 1.5 times larger than the current day entire global economy. The demand for fresh water will increase by 55% 3.9 billion people will be living under severe water stressed conditions It is predicted that water shortage will occur affecting at least half of the entire population which is more than 4.5 billion people 14. Worlds population 2050 The world population is projected to reach 9.6 billion people, more than half of the population growth is predicted to come from Africa alone. It is predicted that globally, the population of people age 50 or more will triple if compared to the year 2010. In the year 2010 the population of people aged 50 or more is 531 million people but in 2050 it is expected to reach 1.5 billion people. This is caused by the fact that the world as a whole is now declining in terms of birth rates. It is also predicted that the population of children aged younger than 15 is expected to increase by only 10% from 2010. In this year china will have a population of 1.38 billion people which means that it w
