The world's livestock are also expected to be affected by many of the same issues, from greater heat stress to animal feed shortfalls and the spread of parasites and vector-borne diseases. [5]: 746 The increased atmospheric CO 2 level from human activities (mainly burning of fossil fuels) causes a CO 2 fertilization effect. This effect offsets ...
Similarly, an older study found that if 1.1 °C (2.0 °F) of warming occurs between 2005 and 2045 (rate comparable to hitting 2 °C (3.6 °F) by 2050), then under the current livestock management paradigm, global agricultural costs would increase by 3% (an estimated $145 billion), with the impact concentrated in pure pasturalist systems.
The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. [1] The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
According to the projected increase in food production by 2050, water consumption would need to increase by 53% to satisfy the world population's demands for meat and agricultural production. [ 41 ] Groundwater depletion is a concern in some areas because of sustainability issues (and in some cases, land subsidence and/or saltwater intrusion ...
In the United States, agriculture is the second largest emitter of greenhouse gases (GHG), behind the energy sector. [1] Direct GHG emissions from the agricultural sector account for 8.4% of total U.S. emissions, but the loss of soil organic carbon through soil erosion indirectly contributes to emissions as well.

Research in New Zealand estimated that switching agricultural production towards a healthier diet while reducing greenhouse gas emissions would cost approximately 1% of the agricultural sector's export revenue for New Zealand, which is an order of magnitude less than the estimated health system savings from a healthier diet.
