Earth also had very little oxygen. It only began to accumulate as life formed. Scientists think that around 2.7 billion years ago, photosynthetic microbes called cyanobacteria were able to use the sun's energy to convert carbon dioxide and water into food, leaving oxygen gas as the waste produc...
Trees can take in much carbon dioxide (二氧化碳) which may be bad for our environment and produce oxygen for us to breathe. All people know that trees are important to us. Scientists believe human life would be impossible if there were ...
