The earth is warmed up by the heat evolved by the burning of fossil fuels releasing carbon dioxide. On the other hand, the plant is growing by absorbing heat and carbon dioxide by carbon dioxide assimilation. Earth warming comes from the too much heat evolution by burning of fossil fuels and too less heat absorption by plant growth. Global warming can be protected by promotion of plant growth, by promotion of CO2 assimilation, by promotion of CO2 absorption and heat absorption using NOx produced in the burning process.
