It usually begins as flat red spots that appear on the face at the hairline and spread downward to the neck, trunk, arms, legs, and feet. Small raised bumps may also appear on top of the flat red spots. The spots may become joined together as they spread from the head to the rest of the body.

such as aluminum, glass, cardboard. 

2. Most insects have particular predators such as a specific animal or bird that eats them as a major or sole portion of their diet. 

3. Do not plant 100% of the same plants and trees across the area. 
Do not harvest all of a species during a normal growth cycle. If a tree takes 50 years to grow to harvest size, schedule cuttings to avoid extinction of that tree within the area.
