Eating beef isn’t great for the environment. But can someone who occasionally snacks on cows still be in favour of conservation and other ecological causes? (Image Credit: Gellinger, Pixabay licence, Image Cropped)
Today I want to talk about a tweet. Or more accurately, the attitude to sustainability that this tweet represents. It occurred during the recent Ecological Society of Australia conference, and went roughly thus*.
Good to see only vegetarian food at ESA2018. We know that it’s not possible to be truly in support of conservation unless you cut meat out of your diet.
Now for starters, I want to make it clear that I am 100% in support of eating vegetarian. For those of us fortunate enough to be living in relative affluence, vegetarian diets are easy to maintain, generally cheaper (based on personal experience), and have a proven positive impact on the climate. I’m not completely vegetarian, but I take a lot of steps to minimise my diet’s climate footprint. It doesn’t take much.

Climate change is something that we hear about on a daily basis. The dire warnings tend to concern sea levels rising and temperatures varying so much that we have more intense and deadly storms than before, but these are all direct effects of the climate. Another thing that climate change can do is have indirect effects on organisms.
Organisms with complex life cycles spend the juvenile part of their lives in one environment before moving on to the adult stage in another environment. The researchers in this study wanted to know how simulated climate change during the juvenile stage of the organisms lifetime could affect the adult stage.
