About the Presenters and Potomac Middle School

Sustainability Education at the Middle School LevelWhat is it, why is it important, and what are we doing at Potomac Middle School?

What is Sustainability? The United States Environmental Protection Agency

defines sustainability as creating and maintaining the conditions under which nature can exist in productive harmony, which permits the fulfilment of social, economic, and other requirements of present and future generations.

Why does it matter? Humans continue to utilize natural resources at an alarming

rate Significant concerns about the unintended social,

environmental, and economic consequences of rapid development

Sustainable communities manage to eliminate these concerns by thinking about how to reduce their environmental footprint and become self sufficient

Urban farming is at a sharp decline and our food output may not match need within our lifetime

Why is the Urban Agriculture Program at PTMS Important?Why bother with an Aquaponics system?

USDA Defined Food Deserts

2015 Mega Drought NASA Drought Study

United Nations FAO A revolution in agriculture is vital to meet world food

targets. Food production levels must double in order to feed the

world population by 2050. Water conservation helps in reducing chance of future

wars

War over Water Countries will begin to fight over water, not oil Water is vital to survival and will be worth fighting for Potential hot-spots could include

United States and Mexico Senegal and Mali Bangladesh and India Israel and Jordan Egypt and Sudan India and Pakistan

Why Aquaponics? Easily scalable Productive year-round Up to 10 times faster growth than traditional soil

garden Conserves water and other resources No pesticides or herbicides required Economical

Aquaponics

Traditional Gardening vs. AquaponicsTraditional Soil Garden

Daily watering Use of fossil fuel powered

machinery Uncontrolled environment

Bugs, deer, squirrels, etc. Labor intensive Compost, fertilizer, or other

nutrient rich medium needed Takes up to twice as long to grow

Aquaponics 90% less water than soil Can be designed to run on

renewable resources Controlled environment means

no pests No weeding or heavy labor after

initial build Fish fertilize plants Can grow in half the time
