ORIGINAL: Kirata These refer to the absorption of nitrogen, which reduces protein content. But, plants are not our primary sources of protein. So what are our primary sources of protein? Is it the animals that get their protein by eating the plants that are losing their protein? quote:
ORIGINAL: Kirata In fact, elevated CO2 has been shown to increase the content of flavonoids, phenolic compounds and other anti-oxidants, for example in Maylaysian ginger, a link to which I happen to have at hand (here), but other species as well, strawberries in particular. Epidemiological studies revealed that flavonoid-rich diet is correlated with the increased longevity and decreased incidence of cardiovascular diseases . . . In addition to their antioxidant properties, flavonoids have been reported to exhibit other multiple biological effects, e.g. antiviral, antibacterial, anti-inflammatory, vasodilatory, anticancer, and anti-ischemic. Moreover, they are able to inhibit lipid peroxidation and platelet aggregation and improve increased capillary permeability and fragility ~Source Wow great... I guess we don't even need protein. quote:
The first of these discovers that more plants require more water. Who would have guessed? The second, however, reports: Plants give off water through tiny pores in their leaves, a process called evapotranspiration that cools the plant, just as perspiration cools our bodies. On a hot day, a tree can release tens of gallons of water into the air, acting as a natural air conditioner for its surroundings. The plants absorb carbon dioxide for photosynthesis through the same pores (called stomata). But when carbon dioxide levels are high, the leaf pores shrink. This causes less water to be released, diminishing the tree's cooling power. In other words, with elevated CO2 plants require less water, which allows any given water resource to support more growth. A new study from the University of California, Irvine and the University of Washington shows that water conserved by plants under high CO2 conditions compensates for much of the effect of warmer temperatures, retaining more water on land than predicted in commonly used drought assessments. According to the study published this week in the Proceedings of the National Academy of Sciences, the implications of plants needing less water with more CO2 in the environment changes assumptions of climate change impacts on agriculture, water resources, wildfire risk, and plant growth. ~Source Okay, so how much time does that buy them in the face of ever-rising temperatures that they are now directly contributing to? It's not just about plants and their ability to retain water, it's also about the effect that the warming they will now be producing has on the soil. So what is the upper limit to how much warming plants can take, and what is the upper limit to how much warming the soil can take? I mean, we're not just talking about whether plants can survive in the near-future, we're talking about increased warmth and CO2 leading to increased release of CO2 from soil AND plants... so all of that 'new' CO2 being released from the soil and the plants isn't going to push global warming past the point where these plants can survive? Under which emissions scenario? A single summer in which Trump-era emissions standards are combining with increased CO2 production from both soil and plants and probably fires (releasing still more CO2) and for argument's sake let's throw in a naturally occurring warm spell... would lead to what? https://www.sciencedaily.com/releases/2017/01/170130140004.htm I also don't really understand what your position on this whole matter is. Maybe you think that all of this plant growth, which you seem to think will continue indefinitely, means we should not worry about the future, which is bright and good, all thanks to everyone's friends the fossil fuel industry.
