Overpopulation

Here's a video that i've found in Youtube. Hope you like it!

The world population is increasing rapidly, especially in the second half of the 20th century in 2005, the world population was 6477 million.
The population explosion in the world today takes place mainly in the developing countries. These countries take place for about 80% of the population and 95% of the annual population increase of the world.
Causes of Overpopulation:
_Decline in the Death Rate:The world population is getting older . In the age structure, the proportion of people under 15 years increasingly low, the rate of people over 65 increasing and life expectancy of the world population increasing.
_Better Medical Facilities:Following this came the industrial revolution. Technological advancement was perhaps the biggest reason why the balance has been permanently disturbed.Better medical facilities, the longer people will live=> the world loss its balance in population.

Effect of overpopulation:
_Depletion of Natural Resources:This is covered by one of the many laws of physics in which our planet is governed. Oil is used for everyday objects such as all plastics, toothpaste, tires, and most commonly known for fuel to run machines. According to the International Energy Agency in 2008 the world uses eighty-five million barrels of oil per day which is putting oil on a nine percent decline from the top of the bell curve. The top of the bell curve of oil also known as the peak was announced in 1970. Iraq has about ninety billion barrels left in its reserve which seems like a lot, but only one billion barrels will last for about eleven days and oil cannot be replaced. 
_Global climate change and ozone layer depletion: The amount of CO2 in the atmosphere increased dramatically causing the greenhouse effect, causing the earth's temperature to rise. Estimates within the past 100 years, the earth had been warming of 0.6 degrees Celsius. Forecast in 2100, the Earth's temperature will rise between 1.4 ° C to 5.8 ° C.
_Rise in Unemployment: When a country becomes overpopulated, it gives rise to unemployment as there fewer jobs to support large number of people. Rise in unemployment gives rise to crime as people will steal various items to feed their family and provide them basic amenities of life.
_High cost of living:

Solution of overpopulaiton :
_Tax break:Couples with more than three children can be taxed heavily as it will help people stop producing children, as they are given a more favorable deal.

_Sex-education.
_Sex education needs to be made mandatory in schools so that we do not suffer the consequences.
_Health care
_Providing the children and new mother´s proper health care is one of the best solutions to overpopulation as their mortality rates will be reduced.

Prediction:
_I think, in 2100 the world population with reach 10 billion. Because there are some good solution had been applied into law.So positively, I belive people can handle this problem. And the world will be more balance and become a better place without Depletion of Natural Resources or something like that.

What do humans need ?

Maslow(1943): presented the human need through clear classification with following priority. Then in 1991 Max-Neef show another classification base on Maslow's publication. Now we shall analyze the advantages and disadvantages of each opinion.
Maslow: He had classifies human needs to groups from low to high priority. Basicly,
if we do not meet the competition of the lowest priority then to reach the higher priority do not mean anything. From there, we can see the extent necessary of lower needs. Because of it, we have to find to fine way to satisfaction all the needs from low to high.EX: For the administrators, if they want manage people. They also have to find ways to find ways to satisfy the need courage crab workers so they can devote to justify.However,the disadvantages of Maslow is his needs are too general needs that can easily be confuse by two or more type of need. So, if we want to apply one perfectly. We need to have experienced and accurate assessment of the situation we are facing with.
 


Max Neef: About Max, his needs are division form general to specific needs( more detail),so people can easily see one incident belongs to a given group.For example, the table below, we can easily classification according to launching different type. But Neef did not pointed out the important of each needs and also how can we use it appropriately.

Conclusion:each one show about have their own advantages and disadvantages. But when we put two states together then we can also identified all that term correctly include how important it is.

What do you think is the most important issue happening today?

            The most important issue that occuring today is the disease of ebola. Ebola is the sickness that comes from the unsanitary lives of the South African. it is a fatal contagious disease that can be transmitted through several different ways: respiratory system, excretion system or from carriers such as household pets and vermin. it can be compared to Black Death itselve; it is exstremly easy to the virus to spread as it has taken about a thousand of the South African's life. One has to recognize this disease right away or else it can cause dangerous health problem. Ebola affect the life expectancy and the GDP of South Africa and other countries in the world. These many deaths seriously effect the amount of workforce; thousand of bussinesses were shut down cause of the lack of emloyees. Their is no exact cure to this disease, therefore people in the world, especially people in those countries near South Africa , are panicking at the quick spread of  ebola and the only thing they can do is hoping that another Black Death don't appear again.
