Animal agriculture worldwide encompasses 83% of farmland (but only accounts for 18% of the global calorie intake), and the direct consumption of animals as well as over-harvesting them is causing environmental degradation through habitat alteration, biodiversity loss, climate change, pollution, and trophic interactions.

A recent study testing the effects of Bt corn pollen dusting nearby milkweed plants on larval feeding of the monarch butterfly found that the threat to populations of the monarch was low. [12] The use of GMO crop plants engineered for herbicide resistance can also indirectly increase the amount of agricultural pollution associated with ...
The vulnerability of agriculture to climatic change is strongly dependent on the responses taken by humans to moderate the effects of climate change. [6] Changes in crop and livestock viability are forcing the farmers to find better choices of crops and animals, capable of adaption to temperature changes and water availability.
The claim: Climate change has only had 'positive effects' on global food production. An Oct. 20 Facebook post (direct link, archive link) includes a graph that shows global wheat, rice and coarse ...
Management techniques range from animal management and housing to the spread of pesticides and fertilizers in global agricultural practices, which can have major environmental impacts. Bad management practices include poorly managed animal feeding operations, overgrazing, plowing, fertilizer, and improper, excessive, or badly timed use of ...
Crop water intake is also calculated using potential evapotranspiration. Dust emissions have increased as a result of land use, industrial development, and animal grazing, particularly in the western United States. Furthermore,"Dust emissions in some regions have increased by up to 400% in the past several decades". [5] Inorganic dust (minerals)
Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations ...
Jul. 21—Monday's crop-dusting helicopter crash in Elgin is bringing the safety concerns of the industry to the forefront. Accidents are unfortunately commonplace, said Terry Hamilton of Mower ...
