We burned millions of years of plant growth within a few hundred years. Trees alone won’t make a dent within the time frame that’s necessary to stave off that 2 degrees increase. Even if we covered every square meter on the planet with trees. We need to start using every solution we can think of to slow down climate change within a few generations. This includes natural solutions like trees, plants and algae and man made solution like sequestering, direct air capture and even geo engineering.
