Explain why oxygen is needed by cells and carbon dioxide must be removed. Other than the fact that it is odorless and colorless, what makes CO so dangerous? Why does air move out of the lungs during expiration? Explain why low blood pressure is considered a potentially dangerous condition. ...
Why is methane such a potent greenhouse gas? Why are only slightly higher atmospheric levels of carbon monoxide gas dangerous? How do plants detect volatile organic compounds? Why are the molecules of hydrocarbons nonpolar? Why is nitrogen classified as a greenhouse gas?

Hopefully, we will find that CDR is actually a source of economic acceleration. I want to be very careful about predicting what the technology is going to look like in 30 years. That’s dangerous. But at the same time, technologies tend to deliver ...
CO binds to haemoglobin for which it has 200 times more affinity than oxygen and forms carboxyhemoglobin. In blood, when the concentration of carboxyhemoglobin reaches 3-4, the oxygen carrying capacity of the blood is greatly reduced. In other words, the
We've all seen our scientists explaining what global warming is, why it's dangerous, and what we can do to stop it. We put the blame on fossil fuels and auto emissions(排放).But the meat industry is often unnoticed as a major cause, which produces more greenhouse gases than all the ...
Why is nitrogen dioxide dangerous? Nitrogen dioxide causes a range of harmful effects on the lungs, including:Increased inflammation of the airways; ... Reduced lung function; Increased asthma attacks; and. Is nitrogen dioxide harmful to humans?
Polluted air and steadily rising temperatures are linked to health effects ranging from increased heart attacks and strokes to the spread of infectious diseases and psychological trauma.
The first of these, known as “carbon removal” or “negative emissions technologies,” is something that scholars now largely agree we’ll need to do in order to avoid dangerous levels of warming (see “One man’s two-decade quest to suck greenhouse gas out of the sky”). Most n...
Upto 350 ppm, it is both a good raw material as well as essential for keeping the earth warm. However, when its concentration rises, it becomes pollutant because it results in global warming. The letter is quite dangerous because it is melt polar ice, raise the water level of oceans and...
