Animal-derived food plays a larger role in meeting human protein needs, yet is still a minority of supply at 39%, with crops providing the rest. [ 79 ] : 746–747 Out of the Shared Socioeconomic Pathways used by the Intergovernmental Panel on Climate Change , only SSP1 offers any realistic possibility of meeting the 1.5 °C (2.7 °F) target ...
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 ...

Pesticides may appear in surface water due to: direct application (e.g. aerial spraying or broadcasting over water ...
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 ...
These are demand-side changes, ecosystem protections, mitigation on farms, and mitigation in supply chains. On the demand side, limiting food waste is an effective way to reduce food emissions. Changes to a diet less reliant on animal products such as plant-based diets are also effective. [34]:
[100] [101] According to the IPCC 2019 Special Report on the Ocean and Cryosphere in a Changing Climate, the viability of species is being disrupted throughout the ocean food web due to changes in ocean chemistry. As the ocean warms, mixing between water layers decreases, resulting in less oxygen and nutrients being available for marine life. [102]
The USGS links dust events to a decline in the health of coral reefs across the Caribbean and Florida, primarily since the 1970s. [30] Climate change is raising ocean temperatures [31] and raising levels of carbon dioxide in the atmosphere. These rising levels of carbon dioxide are acidifying the oceans. [32]
