Explain how global issues can cause problems in

An Unfair Welcome

Industrialized Nations Can Either Produce Enough
Food or Afford to Import Enough Food

• Yet poverty still exists in these countries.
• Poverty limits food availability

4
Global Hunger is a Complex Problem

• Food production too low
• Distribution problems
• Lack of services needed (like electricity)
• Lack of food storage to protect from animals,
  insects, mildew, etc
• Transportation problems (vehicles, roads)
• Natural disasters (droughts, floods, etc)
• Rapid population growth
• More land gets used for housing vs producing
• Developing nations have greater population growth
• Fuel shortages and costs
• Conflicts and politics

Global Water Problems Add to the Challenges

• Water covers ¾ of the earths surface, but 98 of
  it is undrinkable.
• 2 is fresh or drinkable, but 75 of it is frozen
• Therefore less than 1 our earths water is
  available for humans, crops and farm animals.
• Prediction By 2050, up to 7 billion people in
  60 countries will face a water scarcity.

Water Contamination

• Water must be used over and over
• Rainwater runs off land carrying oil, gasoline,
  garden chemicals, and animal waste from roads,
  yards and farms into the water supply.
• Chemicals poured down the sink travel to water
  supplies.

7
Human and Animal Waste

• Sewage treatment plants cant handle all
  pollutants.
• In developing countries there may not be any
  sewage treatment.
• 1.4 million children under age 5 die each year
  due to contaminated water.

Practice Sustainable Living

• Achieving economic growth while protecting the
  environment and promoting human well-being.
• Organic Farming
• no pesticides or artificial fertilizers.
• Stresses resource conservation
• Soil is fertilized with compost and animal manure

9
Practice Sustainable Living

• Alternative Farming Methods
• Agroforestry raising shade loving plants under
  the shelter of trees.
• Hydroponics plants grown
• without soil. Plant is held in water,
• gravel or sand and fed nutrient
• enriched water.
• May occur on rooftops.
• Aquaculture raising seafood in enclosed areas
  of water, such as a fish farm. By 2010,
  aquaculture will provide over 1/3 of all fish
  eaten in the US.

Practice Sustainable Living

• Take a reusable cloth bag to the store instead of
  using plastic bags.
• Use public transportation, bike or walk instead
  of driving.
• Eat local produce
• Cook enough to freeze leftovers instead of buying
  pre- made, prepackaged meals.

Summary

• 15 of our world goes hungry everyday.
• Each week, there are 50,000 people in Maryland
  relying on emergency food programs - food
  pantries, soup kitchens and shelters - to put
  food on the table for their families. More than
  one third are children and elderly.
• The reasons are many, but we can do our part by
  practicing sustainable living and participating
  in our school food drive!
