Livestock farming requires valuable land to grow fodder, uses vast amounts of freshwater and contributes to global warming through methane and nitrous oxide emissions. And, for many consumers it is important to prevent animal suffering. For these reasons, the global market for meat alternatives is currently worth €6.7 billion to €8.1 billion per year and is projected to grow 8.1% to 12.3% each year over the next decade.

A spectacular fossil site in Canada contains 567-million-year-old creatures that may represent some of the earliest animals to move, reproduce sexually, and develop recognizable body plans. The discovery pushes key evolutionary milestones back by up to 10 million years and suggests complex animal life may have first flourished in the deep ocean.
