Interrelationships between the Environment and Food Production
نویسنده
چکیده
Food has to be extracted from the natural environment of land, water, climate, flora, fauna, solar energy, fossil fuels, and other natural resources needed for the production of crops, livestock, and the like essential for adequate diets. These requisites for food production must be provided by the Earth’s materially closed, finite, and nongrowing ecosystem with a limited throughput of solar energy. The interrelationships between the natural environment and food supplies were apparent for nearly everyone in agrarian societies, but in urban-industrial ones they are often forgotten. All human activities depend ultimately on complex interactions among ecological and social systems. The ecological limits to the expansion of food production cannot be deduced by a reductionist analysis of particular components of ecological life-support systems, such as agricultural land, forests, fresh water, biodiversity, or climate, for example. This is because of the numerous positive and negative feedback at all levels among these components, along with socioeconomic systems that would have to be taken into account.

An experiment was conducted to determine the differences in body weight (BW), feed intake (FI) and some egg production traits of two strains of layer chickens (Isa Brown and Nera Black) and correlate the relationships between the tested traits. The study commenced when the layers were 26 weeks old and a total of 200 (100 of each strain) were used. Sixty fresh eggs (30 from each strain) were col...
