In order for conventional agriculture to produce a fast yield in consumer markets, many synthetics are added to the soils and the diets of livestock for fast growth.
Consider all that is put into the soil in addition to the natural ingredients of air, water, minerals, organisms and leaf litter. Added items include pesticides, herbicides, fungicides, fertilizers. For livestock operations, consider the additional components of hormones, antibiotics, preservatives and additives. Some of these may be needed, but many are questioned by various health agencies and consumer groups.
These items are potentially hazardous to humans, according to your authors. Thus, they ask us to consider the topics of alternative or sustainable farming, organic farming, and integrated pest controls.
Find an article on bioaccumulation or bio magnification of conventionally used agricultural agents in species and human consumers (if you can) and summarize your findings! Don't forget to document your sources. What is your conclusion?
2) Earth states 3% of our water resources is fresh water.
Observe, in various parts of the USA and the world, the need for fresh water. Can we build a more efficient means to capture water? Can we plan to use native plants instead of installing non native plants that require extra water?
If we worked around water, instead of interrupting its flow, how would this change the way we build our communities? How can ecological planning be applied to city or community planning? Give an example.
Did you know that the EPA issues guidelines for what is acceptable levels of 'particulates' in water and that you have a right to your water report?
3) Sustainable Agriculture Technology - what is it?
Why is it best to purchase these vs. 'conventional' foods? Did you know there are NO labels for GMO's (genetically modified foods)???
What do you think? What is your conclusion?
4) All around the world, there is a need for fresh quality water. Can we do a better job at conserving and protecting our water resources? What is water quality? How is it defined?
Last but not least: summarize the Clean Water Act and note how it is applied where you live. Do you know who to contact if you have a concern about clean water? Who would that be?
Water management is a very important aspect of every community. Here are some things to think about:
Water resources need conservation, purification, protection from run off, thermal pollution, industrial and agricultural pollution. How can we eliminate this sign?
What water issues exist in your community?
• Find out what aspects of water management your water department is currently working with!
• What kind of waste water treatment facility do you have? How does it work?
• Find out which water resources are protected wildlife habitats or natural resource areas.
• What is the water protection plan where you live?
• Who can you work with to resolve water quality problems?
