Bummer: Slight increases in airborne plant food will allegedly cause 24 million more children to be malnourished by 2050

Poor diet kills 2.6 million infants a year, says survey by Save the Children | Global development | guardian.co.uk

The UN World Food Programme has predicted meanwhile that 24 million more children will be malnourished by 2050 as a result of climate change.

Hydrofarm - Carbon Dioxide Enrichment Methods

Below 200 PPM, plants do not have enough CO2 to carry on the photosynthesis process and essentially stop growing. Because 300 PPM is the atmospheric CO content, this amount is chosen as the 100% growth point. You can see from the chart that increased [CO2] can double or more the growth rate on most normal plants. Above 2,000 PPM, CO2 starts to become toxic to plants and above 4,000 PPM it becomes toxic to people.

This has been the most common method of CO2 enrichment for many years. A number of commercial growers and greenhouses use it in their larger structures. The most common fuels are propane, butane, alcohol and natural gas.
