if the level of CO2 was lowered by 20% there would be no chance that they could grow back is true

More co2 means less disease, less water consumption needed. Healthier, bigger crops.

We need a 50% increase

hold on a second, how is less water consumption needed? if a plant is photosynthesising then it needs one mole of water to one mole of CO2 so it definitely would not need less water by any means. and how is it going to cause less disease?

*6 moles of water to 6 moles of CO2

More co2 means trees and plants will grow in more arid regions

ok so why are we seeing accelerated desertification instead of more vegetation in arid and semi arid regions?

There is some other things as well but i think your mind is closed so you wont even bother looking into it. So i wont mention it.

ok so as someone who tried to disprove climate change you'r telling me that my mind is closed?

@Koro we are not seeing desertification. We are seeing a greening earth

i think i'm actually talking to a debate troll

so the fact that india in its entirety is at risk of desertification is us not seeing desertification? and the masses of deforestation and less growth in arid and semi arid regions is a greening earth?

Show me your data.

Ok. Show me the data of your experiment from someone else

Show me how you know earth is becoming greener and not unhealthier.

I don’t have any data to show, I’m not the one making arguments.

Plant a seed

Watch the weeds spread

Watch the grass grow

If you actually think that is going to do anything to Earth, you are extremely stupid sir.

Plus, that isn’t even data.

That’s just stupid blabber.

if i plant a seed in the uk and a seed of the same species in the middle of mali are they going to do the same thing? no

i can't attach images here so i can't show u the picture

From your Oracle.

so the majority of that is going to be agriculture which is harvested only for the CO2 to be released once again. how much of that is there to stay for a long enough period to matter?

so yeah the world's food supply is increasing. who is surprised about that? it has to

Did you just grab the article thinking it was in your favor or did you actually read anything?

I read it

Its not very long

Since I can’t post images...

“While rising carbon dioxide concentrations in the air can be beneficial for plants, it is also the chief culprit of climate change. The gas, which traps heat in Earth’s atmosphere, has been increasing since the industrial age due to the burning of oil, gas, coal and wood for energy and is continuing to reach concentrations not seen in at least 500,000 years. The impacts of climate change include global warming, rising sea levels, melting glaciers and sea ice as well as more severe weather events.

The beneficial impacts of carbon dioxide on plants may also be limited, said co-author Dr. Philippe Ciais, associate director of the Laboratory of Climate and Environmental Sciences, Gif-suv-Yvette, France. “Studies have shown that plants acclimatize, or adjust, to rising carbon dioxide concentration and the fertilization effect diminishes over time.”

“While the detection of greening is based on data, the attribution to various drivers is based on models,” said co-author Josep Canadell of the Oceans and Atmosphere Division in the Commonwealth Scientific and Industrial Research Organisation in Canberra, Australia. Canadell added that while the models represent the best possible simulation of Earth system components, they are continually being improved.”

It explains to your face that the growing amounts of carbon dioxide isn’t beneficial if it continues.

Show the data

so mass agriculture is fair enough as greening but it releases as much CO2 as it absorbs and more via the need of equipment to harvest it

It’s literally right from the site that you linked.
