Modified plants to curb climate change
(PHYSorg.com Biology)

Each year, an average of 120 gigatons of carbon dioxide (CO2) worldwide is released through soil and vegetation respiration. Plants are capable of taking in nearly 123 gigatons through photosynthesis in the same period. But as humans release another ten gigatons of carbon dioxide into this cycle, mainly by burning fossil fuels such as crude oil and natural gas, there are seven gigatons of excess CO2. `And these seven gigatons are our big problem,` says Thomas Dandekar who holds the Chair of Bioinformatics at the University of Würzburg. They fuel global warming and cause global temperatures to rise at an alarming rate.
