Lab Grown Meat

'Cultured meat could potentially be produced with up to 96% lower greenhouse gas emissions, 45% less energy, 99% lower land use, and 96% lower water use than conventional meat.'

 'our research shows that cultured meat could be part of the solution to feeding the world's growing population and at the same time cutting emissions and saving both energy and water. Simply put, cultured meat is, potentially, a much more efficient and environmentally-friendly way of putting meat on the table.'

I certainly hope this becomes more popular. The fact that it also doesn't involve harming animals is a plus.
