Improving animal welfare is promising focus area. One strategy for improving animal welfare is to reduce consumption of animal products. Creating more attractive alternatives to meat, dairy products and eggs may help to encourage more people to reduce consumption of these products, and so reduce the suffering caused by factory farming (Rorheim et al 2016).
This is likely to be best achieved through some form of life sciences research. For example, recent research has looked into the possibility of creating cultured meat, which is meat grown cell-by-cell in laboratories without any animals being involved (Open Philanthropy Project 2016).
