Even more than the FAO researchers, Rabbinge sees the trend towards the intensification of livestock production as the solution to environmental problems. She fears that intensive livestock production could result in many other, perhaps even greater environmental problems, such as the acidification and overuse of water supplies, and the loss of biodiversity.

Also, in many countries, animals are an integral part of the agricultural systems of small farmers.

Based on her research into the sustainability of animal production systems in developing countries, van der Zijpp believes that part of the solution lies in encouraging the consumption of meat typing jobs from home south africa other types of animals, particularly non-ruminants such as pigs and poultry because they emit less methane.

Through economies of scale and efficiency improvements, businesses would be in a position to invest more in environmentally benign technologies. Leemans concludes that while the FAO report gives a coherent overview of the influence of the livestock sector on climate, it is not appropriate to compare it with other sectors. Steinfeld, S. In fact, insects produce the most animal protein per unit of food consumed.

Areas where intensive production systems are already in use are indicated in red. Cattle have a low food conversion efficiency: Ehui and C.

However, research indicates that the storage of CO2 in grassland can also make a contribution, sometimes more than in woodlands. Environmental Issues and Options.

The reason for this is the shorter lifespan of insects compared with cattle, and the fact that they are cold-blooded and so do not require energy to keep warm.

Steinfeld, P. Wassenaar, V. Genetic engineering, for example, could be used to breed animals that can convert food more efficiently, or the composition of the feed could be altered so that it produces less methane. Finally, CO2 itself is released as a result of land degradation due to overgrazing, deforestation and the conversion of grasslands for cultivation. Scientists agree that livestock are a significant source of greenhouse gas emissions, but not all of them endorse the proposed solution — more intensive livestock production.

Rosegrant, H. The IPCC reports, typing jobs from home south africa which senior scientists from all over the world contribute, apply much stricter scientific standards that do not allow such overlap.
