If the amount of carbon dioxide is increasing, it doesn't make sense to diminish the vegetation (photosynthesis). Therefore we should eat meat and preserve the vegetationIn his documentary, Al Gore states that carbon dioxide contributes substantially to global warming or climate change and that humanity needs to find alternative ways of generating energy, like for example, we need cars that emit less or zero carbon carbon dioxide instead or today's cars that emit a lot of carbon dioxide.
