Skeptics claim that the Carbon Dioxide that is being released by the burning of fossil fuels is actually good for the environment. Their argument is based on the logic that, if plants need CO2 for their growth, then more of it should be better. We should expect our crops to be more abundant and our garden flowers to grow taller and bloom brighter.
However, this “more is better” philosophy is not the way things work in the real world. There is an old, wise saying that goes, “Too much of a good thing can be a bad thing.” For example, if a doctor tells you to take one pill of a certain medicine, taking four is not likely to heal you four times faster or make you four times better. It’s more likely to make you sick.
It is possible to help increase the growth of some plants with extra CO2, under controlled conditions, inside of greenhouses. It is based on this that Skeptics make their claims. However, such claims are simplistic.
Skeptics fail to take into account that a warmer earth will have an increase in deserts and other arid lands which would reduce the land there is available for crops. The corn in Kansas isn’t going to prosper from an increase in CO2. Cactus, though, will be very happy growing where corn used to grow.
