You can't just look at the number and say "Oh, that's very small so it won't matter" without considering the broader context. For example, you might look at a pile of compost containing two parts per billion (0.0000002%) of aminopyralid and say "Oh, that's a tiny amount! My tomatoes and potatoes will be fine growing in that." It will still kill them though, along with many other vegetables.

What utter unrelated tosh!
When CO2 levels fall to 150ppm ALL plant life dies and the world dies with them.
Millions of years ago CO2 levels prior to the advent of calcerous animals was at 6000ppm. (Climatologists are presently predicting about a 1.0°C rise give or take per 100ppm of extra atmospheric CO2. What they can't explain is how the Earth could possibly have survived temperatures some 56°C higher than now all those millions of years ago).The evolution of these animals has seen CO2 levels fall to 300ppm trapped in trillions of tons of chalk and limestone deposits across the world. This starvation of CO2 has resulted in deserts expanding across Africa, Asia and the Americas as the plant life in arid climates being most sensitive to low levels of CO2 recedes.
Before spouting such drivel, you should take the time to listen to Ned Nikolov's podcast the link to which I provided in my previous post. Then you might just grasp the reality of the adiabatic processes that govern climate through their influence on cloud albedo.
And to be clear, I disagree with Ned Nikolov. Whilst Ned has scientifically proven that CO2 has no direct effect on climate I am persuaded that CO2 levels affect greening which helps retain atmospheric moisture thereby having an effect on albedo. In other words, CO2 is a net cooling gas and if we want to save the planet we need to reverse the effects of millions of years of calcerous animal carbon capture and release CO2 into the atmosphere and the easiest way to do that is to burn fossil fuels.
JBM calls me blinkered. But what he fails to appreciate is that this is a conclusion I've reached as trained scientist schooled in entropy, enthalpy, nuclear physics, molecular energy states, ideal gases and fluid mechanics, spectrophotometry, plant and animal biology etc etc etc and as a member of the UK Citizens Assembly on Climate Change after many hundreds of hours digesting the scientific evidence of CO2 and climate.
Simply repeating a false mantra doesn't change the facts.
