This is misleading. In a sharepic it is said that a CO2 reduction makes no sense because CO2 is for plant growth is needed. It is claimed that the additional CO2 in The air is necessary so that plants can convert it into oxygen and which in turn is used by animals and people. The sharepic was recently shared on Facebook. However, it has been haunting since 2019 social media and forums. ## Evaluation The claim that CO2 reduction leads to less plant growth and Therefore, not helping against climate change is wrong. It is true that Plants need CO2 to produce oxygen. However, it follows from this not that human CO2 emissions have positive effects. Also one Study that says the earth has become greener in recent decades is no evidence for the claim. ## Facts It is true that plants need CO2 and also that they need oxygen produce. However, the claim that a reduction in the of Human-generated CO2 leads to less plant growth, over the target out. Even before humans started producing large quantities of CO2 Plants thrived. Just because plants rely on CO2, that is not that more and more carbon dioxide leads to unlimited plant growth leads or a reduction necessarily causes plant death. The claim may be based on a 2016 study. In this one The study examines the earth's surface covered by plants. The Researchers find that there was one between 1982 and 2009 There was a global trend towards more greenery. Scientists: More green won't stop climate change The increased CO2 emissions are one of the reasons for this trend stated, however some of the authors present in one Articles that appeared later made it clear that this does not mean that this is the case Climate change can be stopped. On the contrary: the trend towards more green does not even begin to equal the negative consequences of climate change Extreme weather events, sea level rise or acidification seas, out. The website klimafakten.de also states that the fertilizer effect of more CO2 in the air does not compensate for the negative consequences of climate change. In the In most cases, an increased supply of CO2 does not even lead to more CO2 Plant growth. In addition, extreme weather events are increasing due to climate change have a negative impact on plant growth. Instead of benefiting from more CO2, Plants are more likely to scorch or wither. The Austrian one In its review of 2022, the Federal Environment Agency writes of a “year of Extremes». Overall, recent studies suggest that the fertilization effect is negligible. At the same time, it has been scientifically proven that the... Humans caused greenhouse gas emissions for climate change are responsible.

Reducing CO2 to save the climate makes no sense because plants need CO2 and therefore reducing CO2 would lead to less plant growth
