Soil corrosion, chemical substances used in agriculture, loss of genetic diversity, monocultures, overfishing, the chronic malnutrition of 800 million people: these are all food problems of today.
Soil marks the starting point of nutrition. Healthy soil produces healthy food. Soil must be seen as a non-renewable natural resource, since it may require up to 10,000 years for the formation of 10 cm of fertile soil.
Cultivation – means of control
Our food comes from cultivation of plants and animal breeding. For the protection of their cultivations, farmers apply 5 main alternatives of replacing pesticides, namely environmental and biological control, use of genetic engineering, behaviour control and production of tolerant plants. Today, comprehensive parasitism control systems are applied for the restriction of soil and underground water pollution, through the restriction in use of fertilizers and pesticide, thus improving cultivations performance.
The latest evolution in classic genetics, with the contribution of modern technology, is genetic engineering – “tailoring” of special features on parts of the genetic material of organisms called genes.
Genetically processed food might increase food production at low cost. However, the negative impacts of this modern technology to the environment and human health have not been studied yet. There are advantages as well as disadvantages. Nevertheless, the issue is still pending…
All things in moderation. The «hour of truth» comes to make visitors wonder on their nutritional habits. The World Health Organization wants to see all people keep a properly balanced diet. In industrialized countries, people consume 3,340 calories on a daily average. On the other hand, in less developed countries, people consume 2,060 calories daily. If the developed world reduced meat consumption and adopted a diet with fruits and vegetables, there would be enough food for everyone. But today, with the use of chemical substances and antibiotics in feeds, we came to a point where we have to deal with cow madness. On the other side, biological products – produced without the addition of artificial chemical substances – have been introduced to the market and are consumed more and more.
