Cultivating insects for food requires less resources, less land, less water, less transport fuel, and less human labor than animal livestock while possessing a much smaller carbon footprint.
Isn't carbon dioxide a good thing since plants constantly are starved of carbon dioxide and would perform better with more, so wouldn't that help prevent starvation?
Excess carbon dioxide (released through decomposition, fossil fuels, etc) builds up in the atmosphere causes greenhouse gases, which cause climate change.
The effect of carbon dioxide in the atmosphere overall decreases with each carbon dioxide molecule added. It will cause climate change, but it will be extremely small
