For Sikhs, the environment and the forces of nature are regarded as sentient. This means that the wind, water, fire, planets, galaxies, solar systems all praise the One (Guru Granth Sahib Ji: 6).
Animals are regarded as sentient and as worshipping the One. While many Sikhs are vegetarian for this reason, the official view is that it is acceptable to eat meat so long as it does not damage your health and it is not killed as a sacrifice or in a sacrificial way, e.g. halal meat. The reason is that vegetables are also regarded as living things, so why is the discrimination being made? (Guru Granth Sahib Ji: 1189).
