Population Growth Population Growth

Current human population of over 7.3 billion Projected to be over 9 billion by 2050 Population may grow to 13 billion by 2100 We 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. 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, computer, ipad, kindle, etc.)? How many pairs of shoes do you own? U.S. Lifestyle

Globalization of the U.S. Lifestyle Agriculture and Food -- Meat Consumption: Per capita (Units: Kilograms per person) Country Brazil Canada China Denmark France India Mexico United Kingdom United States

From 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 been linked.

Globalization of the U.S. Lifestyle In 2010, the world reached 1 billion cars! The most cars are in the U.S. with 1.3 cars for every person The largest growth however is occurring in China, with 27.5% increase in cars Other rapidly growing economies like India and Brazil have increased demand for cars Transportation accounts for 23% of the world’s greenhouse gases What happens if China and India reach the same ratio of cars to people as the United States?

Two types hunger issues. ◦ 1. Undernourishment – not enough calories ◦ 2. Malnourishment – enough calories, but not nutrients Where is undernourishment an issue? Where is malnourishment an issue? Hunger Issues Hunger Issues

Undernourished Global Population Undernourished Global Population

Food Shortages Food Shortages Can you name some reasons we may have food shortages in the future? Increased demand due to rising population Increased standard of living in developed nations Global warming may increase intensity and frequency of droughts Increase in fuel prices raise the cost of food Corn aborted Summer of 2012 in the U.S.

Malnourishment Malnourishment People 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 food Farm subsidies provide an overabundance of cheap corn. This provides cheap meat in the form of fast food and high fructose corn syrup laden drinks and food. ◦ These foods are linked to diabetes, obesity, and heart disease.

Obesity and Unhealthy Food Obesity and Unhealthy Food Growing obesity rates are directly related to food consumption. The predicted health bill for obesity-related diseases in 2012 is 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. ◦ This trend is increasing; in 1970 only 5% of children were obese.

Pesticides Pesticides

Pesticides & Agriculture Pesticides & Agriculture 1 billion pounds of pesticides are used in the U.S. every year According to Cornell entomologist David Pimentel, “[i]t has been estimated that only 0.1% of applied pesticides reach the target pests, leaving the bulk of the pesticides (99.9%) to impact the environment. Long-term exposure increases the risk of reproductive disorders, immune-system and endocrine disruption, impaired nervous- system function, and development cancers. (WHO 2012)

Residual Chemicals on Produce Residual Chemicals on Produce

Agriculture is the single largest user of freshwater resources, using a global average of 70% of all surface water supplies. Industrial agriculture is one of the leading causes of water pollution in the United States. Agricultural activity was identified as a source of pollution for 48% of stream or river water and 41% of lake water. (EPA: National Water Quality Inventory, 2000)

Overfishing Overfishing

Over 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) How does technology contributes to overfishing?

Overfishing: Atlantic Cod Collapse Overfishing: Atlantic Cod Collapse

Human population is growing at an exponential rate Increasing standard of living for developing countries (more meat, cars, etc.) Increasing access to unhealthy food and limited access to healthy food Extensive use of water and pesticide in agriculture Oceans are being overfished to the point of extinction BUT… Aquaponics can help alleviate all of these issues. Summary

Tilapia - high in protein, 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. fish/#ixzz2eLCuCeBF 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 Swiss chard is a good source of antioxidants. Antioxidants may play a role in the prevention of some cancers, heart disease and Alzheimer’s disease. chard/ What do we grow in Aquaponics?
