Photosynthesis

What is the most important scientific process that takes place on Earth? Many scientists would answer: photosynthesis. This process has made our planet livable for millions of species by providing the materials and the energy that Earth's creatures need. Well-known science writers Alvin and Virginia Silverstein and Laura Silverstein Nunn explain how photosynthesis works, how living creatures on our planet use it, and how it relates to the greenhouse effect and global warming. The authors also reveal current research on photosynthesis, showing ways that scientists can improve food and its availability through genetic engineering, increase energy sources, and fight fatal diseases such as cancer.
