First, absorption helps people by preventing high-energy radiation from reaching the surface which limits our exposure to harmful radiation. The atmosphere absorbs most of the radiation from the ultraviolet region through the X-ray region. The second way in which absorption helps the earth is as a heat source for it.

What Lean Is and Is Not. Lean is not about being skinny and itâs not about âcutting to the bone.â Lean is about having the right resources in place to do the right work for the customer, with the right quality, at the right time. Lean is not âmeanâ (although the words rhyme, unfortunately). Lean is respectful toward everybody who participates in a system, including customers, employees, suppliers, the community, etc. Lean does not mean cutting heads in the name of cutting costs (see âLean is not meanâ).
