When it comes to animal advocacy, not all causes are created equal. To make the biggest impact with your donations, it's crucial to understand which interventions actually reduce suffering per dollar. This deep dive explores the most effective ways to help animals, backed by evidence and expert insights.
Why focus on farmed animals?
Farmed animals account for the vast majority of animals used for food, with over 70 billion land animals and 1 trillion aquatic animals killed for food each year worldwide. Moreover, the lives of farmed animals are often marked by severe suffering, including intensive confinement, painful procedures, and cruel slaughter methods.
Given their enormous numbers and the intensity of their suffering, reducing the impact of factory farming should be a top priority for animal advocates. Organizations like Faunalytics recommend focusing on farmed animals to achieve the most significant reduction in suffering.
The power of legislative reform and undercover investigations
Legislative reform and undercover investigations can generate widespread change and reduce suffering for countless animals. By targeting industry practices and promoting higher welfare standards, these strategies can lead to systemic improvements in animal welfare.

For instance, the campaign to end battery cages in the EU resulted in the improved living conditions for hundreds of millions of hens. Similarly, undercover investigations have exposed industry-wide abuses and driven policy changes, such as the implementation of humane slaughter laws in the US.
Celebrity endorsements: helpful or harmful?
Celebrity endorsements can raise awareness and inspire people to adopt plant-based diets or support animal welfare causes. However, not all celebrity-driven campaigns are equally effective in reducing suffering.
For example, a study published in PLOS ONE found that celebrity tweets had minimal impact on convincing followers to adopt vegan diets. Instead, personal testimonials and evidence-based arguments were more persuasive. Therefore, it's essential to evaluate celebrity-endorsed campaigns critically and consider supporting organizations with proven track records.
Plant-based diets and corporate engagement: driving systemic change
Promoting plant-based diets and engaging with corporations can lead to significant reductions in animal suffering by shifting demand away from animal products and toward more sustainable and ethical alternatives.
For example, the growth of plant-based meat and dairy alternatives has driven down sales of animal products and reduced demand for animal agriculture. Moreover, corporate commitments to higher welfare standards, such as those made by major food companies, can improve the lives of millions of animals.
