We can't depend on plants to slow down global warming


Recently, global warming is the most serious problem all over the world. A new study shows that plant growth from CO2 fertilization won’t slow global warming because Increased future plant growth will not reduce carbon dioxide levels in the atmosphere as much as we thought. Now, we must find a new way on without delay. The authors found that increased CO2 in the atmosphere actually increased the outflow of carbon dioxide from the soils. Natural land ecosystems are unlikely to sequester as much carbon as we had hope. I think the earlier we take action, the easier it will be.
