In a look at recent technological advances that could help the world implement more practices to sustain a healthy environment and clean up those that are threatened by the results of unsustainable human actions. The potential solutions include the carbon capture systems like those being developed by ASU’s Center for Negative Carbon Emissions, directed by Fulton Schools Professor Klaus Lackner. Those systems are able to remove carbon dioxide from the atmosphere, which would help reduce the accumulations of greenhouse gases that contribute to the environmental harm done by global warming.
