Как правильно preseve or conserve natural resources?
Верны оба варианта, смотря, что вы подразумеваете. Отличие вот в чем: When you conserve something, you ensure that you make use of it wisely. You make sure it is not wasted. There is a suggestion that if you do not make careful use of it, then chances are it will be impossible to replace the commodity. Preserve, on the other hand, suggests that you make attempts to keep something as it is, without making any changes. In other words, when you preserve something you keep it intact. You keep it safe, protecting it from danger.
