CO₂ Emissions from Animal Husbandry: A Case Study for Hungary Based on Production Data for 1980

Abstract

Biomass is considered a renewable natural resource. Man’s own activities with regard to biomass production are performed against the background of the global natural material cycles. In order to understand man’s impact on his environment a much more thorough knowledge is required of the entire material cycles on which the continued existence of the biosphere depends. Staple foods are among the most vitally important uses of biomass for man’s existence. In 1990 world agriculture harvested a record cereal crop of 1758 Mt (USDA, 1990a & b; USDA, 1981) a figure that includes only the main products of the biomass, namely the seed fraction of wheat, rice, corn etc, and is expressed on the basis of 14% moisture content by weight.
