Increased intensity of global climate change causes even greater increases of thermal heat index in Jamaican farm animals. High thermal heat index is one of the more widely used indicators of heat stress. [12] In general, the preferred ambient temperature range for domestic animals is between 10 and 30 °C (50 and 86 °F).
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.

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.
Change in weather patterns and temperature due to climate change leads to dispersal of plant pathogens as hosts migrate to areas with more favourable conditions. This increases crop losses due to diseases. [123] [109] For instance, aphids act as vectors for many potato viruses and will be able to spread further due to increased temperatures. [127]
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 ...
According to a new analysis, people worldwide suffered an average of 41 extra days of dangerous heat this year because of human-caused climate change. People around the world suffered an average ...
Stifling heat blanketed tens of millions of people in United States on Tuesday, forcing people and even zoo animals to find ways to cool down as summer arrives in what promises to be a sweltering ...
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 ...
