Facts And Evidence Matter In Confronting Climate Crisis

We recently highlighted the faulty logic of a pseudoscientific argument against addressing climate change: the proposition that because CO2 is necessary for plants, increasing emissions is good for the planet and the life it supports. Those who read, write or talk regularly about climate change and ecology are familiar with other anti-environmental arguments not coated with a scientific sheen.

A common one is that if you drive a car, buy any plastic goods or even type on a computer keyboard your observation that we need to reduce fossil fuel use is not valid — no matter how much evidence you present. Like the “CO2 is plant food” claim, it’s a poor argument, but for different reasons. It’s easy to refute the junk science claim with large amounts of available evidence. This one’s simply a logical fallacy.

It's Been 25 Years Since World's Prominent Scientists Released 'Warning to Humanity'

The longer we delay addressing environmental problems, the more difficult it will be to resolve them. Although we’ve known about climate change and its potential impacts for a long time, and we’re seeing those impacts worsen daily, our political representatives are still approving and promoting fossil fuel infrastructure as if we had all the time in the world to slow global warming.

We can’t say we weren’t warned.

Eating Less Meat Will Reduce Earth’s Heat

Will vegans save the world? Reading comments under climate change articles or watching the film Cowspiracy make it seem they’re the only ones who can. Cowspiracy boldly claims veganism is “the only way to sustainably and ethically live on this planet.” But, as with most issues, it’s complicated.

It’s true, though, that the environment and climate would benefit substantially if more people gave up or at least cut down on meat and animal products, especially in over-consuming Western societies. Animal agriculture produces huge amounts of greenhouse gas emissions, consumes massive volumes of water and causes a lot of pollution.

But getting a handle on the extent of environmental harm, as well as the differences between various agricultural methods and types of livestock, and balancing that with possible benefits of animal consumption and agriculture isn’t simple.
