How Changing Your Diet Can Help the Environment

Eating Lower on the Food Chain

By choosing to eat lower on the food chain, you can make a significant impact on reducing resource consumption and waste generation. When we consume plant-based foods instead of animal-based foods, we decrease the demand for resources like land, water, and energy.

Plant-based diets require less land because growing crops takes up less space compared to raising animals for meat. For example, it takes approximately 200 times more land to produce a pound of beef compared to a pound of soybeans. By opting for plant-based alternatives such as legumes, grains, fruits, and vegetables, we can help conserve precious land resources.

In addition to land conservation, plant-based diets also have a lower water footprint. Animal agriculture requires vast amounts of water for livestock production and irrigation of feed crops. By shifting towards plant-based options, we reduce our indirect water usage since plants generally require less water than animals.

Furthermore, choosing plant-based foods helps reduce energy consumption associated with food production. The process of raising animals for meat involves various energy-intensive activities such as transportation, refrigeration, and processing. Plant-based diets eliminate or significantly reduce these energy-intensive steps.
