WITH THE CARRYING CAPACITY OF ARABLE LAND NOW BEING 1.5 TIMES OVER A SUSTAINABLE FUTURE (PASSED IN 1990) AND NOW INCREASING IN LOSS OF HUMAN SUSTAINABILITY DUE TO SEA RISE AND EXTREME GLOBAL WATER RELOCATION IN WEATHER CHANGES IN FLOODS AND DROUGHTS AND EXTENDED TROPICAL AND HORSE LATTITUDE CYCLONE ACTIVITY AROUND HADLEY CELLS

The World3 model is a detailed simulation of human population growth from 1900 into the future. It includes many environmental and demographic factors.

THIS MODEL BY GUY LAKEMAN, FROM METRICS OBTAINED USING A MORE COMPREHENSIVE VENSIM SOFTWARE MODEL, SHOWS CURRENT CONDITIONS CREATED BY THE LATEST WEATHER EXTREMES AND LOSS OF ARABLE LAND BY THE  ALBEDO EFECT MELTING THE POLAR CAPS TOGETHER WITH NORTHERN JETSTREAM SHIFT NORTHWARDS, AND A NECESSITY TO ACT BEFORE THERE IS HUGE SUFFERING.
BY SETTING THE NEW ECOLOGICAL POLICIES TO 2015 WE CAN SEE THAT SOME POPULATIONS CAN BE SAVED BUT CITIES WILL SUFFER MOST. 
CURRENT MARKET SATURATION PLATEAU OF SOLID PRODUCTS AND BEHAVIORAL SINK FACTORS ARE ALSO ADDED

Use the sliders to experiment with the initial amount of non-renewable resources to see how these affect the simulation. Does increasing the amount of non-renewable resources (which could occur through the development of better exploration technologies) improve our future? Also, experiment with the start date of a low birth-rate, environmentally focused policy.

Физический смысл уравнений Модель Лотки-Вольтерры делает ряд предположений об окружающей среде и эволюции популяций хищников и жертв: 1. Хищная популяция всегда находит достаточно пищи. 2. Продовольственная обеспеченность популяции хищника полностью зависит от размера популяции жертвы.

Физический смысл уравнений
Модель Лотки-Вольтерры делает ряд предположений об окружающей среде и эволюции популяций хищников и жертв:

1. Хищная популяция всегда находит достаточно пищи.
2. Продовольственная обеспеченность популяции хищника полностью зависит от размера популяции жертвы.
3. Скорость изменения численности населения пропорциональна его численности.
4. В ходе этого процесса окружающая среда не меняется в пользу одного вида, и генетическая адаптация не имеет существенного значения.
5. Хищники обладают безграничным аппетитом.
Поскольку используются дифференциальные уравнения, решение является детерминированным и непрерывным. Это, в свою очередь, означает, что поколения как хищника, так и жертвы постоянно пересекаются.

Добыча
Когда умножается, уравнение добычи становится
dx/dt = αx - βxy
  Предполагается, что добыча имеет неограниченный запас пищи и размножается экспоненциально, если только она не подвержена хищничеству; этот экспоненциальный рост представлен в приведенном выше уравнении термином  αx. Предполагается, что скорость хищничества на добыче пропорциональна скорости, с которой встречаются хищники и добыча; это представлено выше в виде βxy.Если либо x, либо y равно нулю, то хищничества быть не может.
С помощью этих двух терминов приведенное выше уравнение можно интерпретировать следующим образом: изменение численности добычи определяется ее собственным ростом минус скорость, с которой она охотится.
ХищникиУравнение хищника становится

dy/dt =  - 

В этом уравнении,  представляет рост популяции хищника. (Обратите внимание на сходство со скоростью хищничества; однако используется другая константа, поскольку скорость роста популяции хищника не обязательно равна скорости, с которой он потребляет добычу).  представляет собой уровень потерь хищников вследствие естественной смерти или эмиграции; это приводит к экспоненциальному распаду в отсутствие добычи.


Следовательно, уравнение выражает изменение популяции хищников как рост, подпитываемый запасом пищи, минус естественная смерть.

The SEQ Koala Population over recent years has suffered due to a number of factors; habitat loss, predators, natural disasters, health issues and road fatalities to name a few.  All the while conservation efforts are being made to aid the population growth of  the national icon.

This insight draws together these contributing factors into a single population model (simulation).  This model begins with the known 2006 population and it projected based on current decline rates.  Accuracy is limited, however the downward trend is clearly evident.

Crime Community Development Population
Insight Maker was utilized to demonstrate the relationship between Alienated Youth, police and Community Development. And the affect of Counselling can have on such youth. The Influence of activities was also depicted that can led to Criminal activities and Drug Abuse among such Youth. The model was made considering the youth within Burke.  

Relationships 
As can be seen that, the police enforcement plays a vital role, in the shaping the lives of youth. Hence, with the Increase in police force and increase in such initiates, the crime is like to decrease. Hence, the youth shall also be kept away from all  of such interactions and such Acts.

Also, the Community Development shall also play a vital role, in two folds. First it shall play a part in shaping the very mindset of youth , to indulge in positive activities and refrain from illegal activities.
Second of all, it shall provide rehabilitation to youth that have been subjected to such crimes and such events.

Conclusion
 It can be Concluded that, with increase in Police enforcement and Community Development, the overall crime can be reduced. The Youth thereupon will only indulge in positive activities.

Variables

There are two Variables involved in the model

1.     Police Enforcement

It measures how effectively and efficiently police go about fulfilling its duties; Identifying potential criminals and stopping them from committing crime and punishing criminal who are guilty.

2.     Community Development

Community development intervenes by changing the mindset of alienated and rehabilitated youth and hence affecting the flow towards Social Interactive Activities.

Adjusting Variables

Police enforcement can be adjusted using the slider given below. There is no choice given to adjust community development as it is affected by various factors of the society; education, culture, morals etc.

Assumptions

Youth engaged in Social Interactive Activities can never become alienated and hence will not go to drugs. In other words, a socially interactive youth member will be engaged in sports, education, gaming or café rather than drugs.

Youth are defined as ages 15-24, comprising of a population of 80. (ABS, 2016)
