You may have this question:where are we getting all the materials for our products? Two words-natural resources  (资源). Natural resources are items we find in the environment. There are two types of natural
resources:renewable   (可再生的) and nonrenewable resources.
Renewable resources are those items that we can get back if weuse them right. For example, when we cut down trees for paper,we can replant new ones. Of course, if we cut down too many trees, destroy the soil and do not replant enough new trees, then we will lose this important natural resource.
Non-renewable resources must be mined (开采) from the earth. If we start using non-renewable
resources wrongly, then we're going to run out ofthem.
Remember, God gives us natural resources to use, not to abuse  (滥用)
