卫星证据确认,持续提升二氧化碳的浓度也在所有植被类型的野生陆地生态系统中导致了生产率提高。
Satellite evidence also confirms that increasing CO2 concentrations have resulted in greater productivity of wild terrestrial ecosystems in all vegetation types.
The concentration of carbon dioxide indoors usually varies between 400 and 1,200 ppm(parts per million) and outdoor levels are between 350 and 450 ppm.
