Now, however, green is usually good. Being green more often means doing good things for the
environment. People who are good at growing plants have a green thumb. Many companies are going
green, which means they are recycling more or are trying to use less energy. In fact, some companies are
moving to new, green buildings, which may use solar power or grow plants on their roofs. So if someone
asks you how green you are, it probably means they want to know if you do good things for the
environment.
