9/8 Bellringer: Global IssuesIf you don’t know, take a guess
1. What is the current world population?
2. What country consumes the most meat?
3. What industry is the largest user of water?
Population Growth
Population GrowthCurrent human population
of over 7 billionProjected to be over 9
billion by 2050We are already using
resources faster than they are being replaced, which is unsustainable.
In the US the consumption of 1 person is equal to that of 32 Kenyans.
Population Growth
How many cars does your family have?
How do you get to school?
How many times a day do you eat meat?
How much meat do you think you eat in a year?
How many personal electronics do you own (phone, ipod, computer, ipad, kindle)?

Between 1961 and 2002, meat consumption has seen a large increase virtually worldwide. There has also been a corresponding jump in its environmental impact.
Increased meat-eating has followed rising affluence in many parts of the world.
Increases in meat consumption and climate change have linked. Why?

The top row is the amount of grain required to produce a pound of raw animal (or milk). The third row shows how much grain is required to produce one pound of edible meat. The fourth row is the efficiency with which plant protein is converted to animal protein.

Poverty and Food AccessPeople of poverty typically suffer from food
insecurity and have more access to fringe food◦ In 2010, 48.8 million Americans lived in food insecure
households, 32.6 million adults and 16.2 million children. (FeedingAmerica.org)
Food insecurity = lack of food accessibility Fringe food = junk foodFarm subsidies provide an overabundance of cheap
corn. This provides cheap meat in the form of fast food locations and high fructose corn syrup.◦ These problems are linked to diabetes, obesity, and
heart disease.
Obesity and Unhealthy FoodGrowing obesity rates are directly
related to food consumption.The predicted health bill for
obesity-related diseases in 2012 is 166.2 million
More than 1/3 of U.S. adults (35.7%) and approximately 17% (or 12.5 million) of children and adolescents aged 2—19 years are obese.◦ In 1970 only 5% of children were
obese.

Pesticides
Pesticides & HealthPesticide and other chemicals
can lead to poisoning.Long-term exposure to
pesticides increases the risk of developmental and reproductive disorders, immune-system disruption, endocrine disruption, impaired nervous-system function, and development of certain cancers. (WHO 2012)

Residual Chemicals on Produce
Overfishing
OverfishingOver 2,000 fish species have gone extinct due to
overfishing. (End of the Line, 2009)More than 70% of the fish species worldwide are
endangered. (FAO, 2009)It is estimated we eat about 10% of the fish that
are caught. The rest, called bycatch, is typically killed by accidental harvest. (BAM, 2009)
Global average consumption of fish is 37 lbs per person per year. (FAO, 2010)
Technology contributes to overfishing.
Overfishing: Atlantic Cod Collapse
Human population is growing at an exponential rate
Increasing standard of living for developing countries
Increasing access to unhealthy food and limited access to healthy food
Extensive use of pesticide in agricultureOceans are being overfished to the point of
extinctionBUT… Aquaponics can help alleviate all of these
issues.
Summary
Tilapia - Fish, such as tilapia, is high in protein but low in fat and relatively low in calories, making it a good food choice.
Unlike many cuts of fatty animal meat, such as beef and pork, tilapia is virtually free of saturated fat, making it a better choice for supporting cardiovascular health.
It is a nutrient-dense food, or one that provides more nutrients per calorie than calories per nutrient. Like all seafood, eating tilapia, as it is a food source of selenium, may reduce your risk of developing certain types of cancers.

What do we grow in Aquaponics?
Swiss Chard - contains 716 percent of the DV for vitamin K, 214 percent of the DV for vitamin A, 53 percent of the DV for vitamin C, 22
Swiss chard is a good source of antioxidants. Promising research shows antioxidants may play a role in the prevention of some cancers, heart disease and Alzheimer’s disease. Antioxidants provide oxygen molecules to free radicals, molecules that attack healthy cells to obtain an electron they need to survive

Chives-might contribute to lower cholesterol and blood pressure, which improves your overall health, particularly that of your heart. Allicin aids in cholesterol management by reducing your LDL levels and increasing your HDL levels. This nutrient might also cut your blood pressure and prevent dangerous blood clots.
