Why do leaves change color in Fall?

As summer ends and autumn comes, the days get shorter. A busy year making flowers and seeds, the trees need their rest and so get ready for winter. Thus, the trees begin to shut down their food-making factories, the green chlorophyll. As it disappears from the leaves, the yellow is left behind briefly until it too is gone and all that is left is the brown, the remnants of a glorious summer and beautiful fall.

What makes the bright reds in Maple trees? These colors and the deep purples we see are glucose trapped in the leaves after photosynthesis stops. Autumn daylight and cool nights combine to produce these brilliant colors.

  1. I am an American man, and I have decided to boycott American women. In a nutshell, American women are the most likely to cheat on you, to divorce you, to get fat, to steal half of your money in the divorce courts, don’t know how to cook or clean, don’t want to have children, etc. Therefore, what intelligent man would want to get involved with American women?

    American women are generally immature, selfish, extremely arrogant and self-centered, mentally unstable, irresponsible, and highly unchaste. The behavior of most American women is utterly disgusting, to say the least.

    This blog is my attempt to explain why I feel American women are inferior to foreign women (non-American women), and why American men should boycott American women, and date/marry only foreign (non-American) women.

    BOYCOTT AMERICAN WOMEN!
