Plants made our current atmosphere and plants can keep it balanced.
When plants first showed up on earth about 3.5 billion years ago, carbon dioxide made up more than 20% of the atmosphere. There was no significant oxygen in the air so More...
The Salk Institute for Biological Studies has a simple solution for reducing atmospheric levels of CO2 without undoing civilization as we know it or denying people in developing countries the right to live as we do. Although Salk believes that More...

Which of these statements is scientific?
Son Jarah was interviewed last week on CRI, China's English-Language equivalent of the BBC. The subject was the possible evidence of neutrinos traveling faster than the speed of light, which came from an experiment at CERN. Here's the show description from CRI:
We all know that nothing can travel faster than c, the speed of light in a vacuum; or do we? A recent experiment called OPERA at CERN measured some neutrinos travelling fractionally faster than c. To be precise: (v-c)/c is approximately 3x10-5More...
"No theory is carved in stone. Science is merciless when it comes to testing all theories over and over, at any time, in any place. Unlike religion or politics, science is ultimately decided by experiments, done repeatedly in every form. There are no sacred cows. In science, 10 More...
