There is much truth in the saying, "you are what you eat"... our food affects our health.
Food Sustainability Tips
-
Grow your own veggies: Your own 'kitchen garden' could be a small field or a cosy window-box. More and more people prefer organic methods - such as Permaculture - avoiding harmful chemicals and improving the condition of the soil.
-
Worm farm: keep your own 'worm farm' to recycle kitchen scraps and other organic waste, then use the liquid vermitea to fertilise your plants. Other options include composting or Bokashi system - see Organic and Worm farming.
Isn’t man an amazing animal? He kills wildlife by the millions in order to protect his domestic animals and their feed. Then he kills domestic animals by the billions (9 billion in the US alone in 1996), and eats them. This in turn kills man by the millions, because eating all these animals leads to degenerative – and fatal – health conditions like heart disease, stroke, kidney disease, and cancer. So then man tortures and kills millions more animals to look for cures for these diseases. Elsewhere millions of other human beings are being killed by hunger and malnutrition because food they could eat is being used to fatten domestic animals. Meanwhile, some people and dying of sad laughter at the absurdity of man, who kills so easily and so violently, and once a year sends out cards praying for “Peace on Earth” – C. David Coats.
Food for thought
- approx. 10% of the energy from the 'primary producer' is transferred to the 'primary consumer'.
- approx. 10% of the energy from the 'primary consumer' is transferred to the 'secondary consumer'.
- thus less and less energy reaches the 'higher' levels of the 'feeding pyramid'.
- Most of the energy lost between each level is transformed into heat.
