Does cutting a vast, vast number of trees down affect the oxygen found in the atmosphere? Does it deteriorate air quality?

Trees breathe in carbon dioxide (a greenhouse gas) and breathe out oxygen, so massive deforestation could increase the atmosphere’s carbon dioxide and reduce the oxygen.

I have found countless times that the river is polluted by hundreds of factories and general human waste. However, i have not found any examples of specific pollutants in the river. Please find the chemicals that are polluting the water and provide me with a source. Thanks

It would be easier to answer the question, which specific pollutants aren’t in there. they have sewage going in, people wash socks and clothes in it,factory pollutants , you name it , it’s there. Here is a link with a picture and a bit of information.

Hope this helps you , Good luck.

Rachel Carson compared the impact of chemical pollutants to the impact of
A. World War II
B. Epidemic plagues
C. Widespread famine
D. Nuclear radiation

and tell me why please. Thanks!

D. Because this kind of pollution (DDT) was invisible to the senses, but it was everywhere: in plants, animals and humans. Because this could result in cancer, birth defects, and genetic mutations, she connected pesticides to a more familiar poison: "Pesticides could be understood as another form of fallout"

Consider the first order reaction: A (g) 2 B (g) with the rate constant equal to 0.0277 min-1. 0.4000 moles of A are placed in a 1.00 L vessel. What is the half-life of this reaction?

i think you could solve this problem using the formula

t1/2 = ln2/k, where t1/2 is the half life you’re looking for and k is the constant, which you’re given
t1/2 = .693/.0277 = 25 minutes

I have a 2006 Cadillac CTS V and the warrany is up and I have never purchased the extended. Now I think it is more than a year later and was wondering if there is some kind of auto repair insurance you can purchase that covers everything and most importantly will let you take your car to a cadillac dealer for service. Thank you.

Find your local agent from Yellow page,and make a call to them,they should have good suggestions for you.

Is it madatory for an auto repair shop to have their business licensing information, as well as mechanic certifications posted where customers can see? Also, what about if a customer asks for this information? What about the mecahnic’s liabilities and the customers rights and responsibilities?

Posted Yes (In the Office most times)

What is the link between pollution and birth rate, why/how are they related? What happened to cause this?

Back then, hippies believed that
The more people, the more pollution.
The more babies, the more Pampers in the landfills.
Now that hippies are aging baby boomers
and wear Depends
they think….nah….it’s just
not that important.

I play trombone in my band and I would like to be able to play more measures without having to breathe every two measures. I also want to be able to play louder without having to take in more air. Can someone help me improve my air quality?

The best thing for you to do is breathing exercised. Getting "The Breathing Gym" would probably help you out immensely. The longer you play, the more air you should be able to use.

I’m supposed to do a poster on air pollution so on one side is stuff that humans can do more to reduce air pollution and on the other side is what humans can reduce on doing that causes air pollution. So my teacher showed us a chart that says the sources of air pollution, one source is agriculture. So my question is how does agriculture create air pollution?

Air pollution is the volume of particulates in the atmosphere. The agriculture process has many contributing factors to pollution, depending on how finite you break it down.

Agriculture is responsible for an estimated 14-25 percent of the world’s greenhouse gases. A significant portion of these emissions come from methane, which, in terms of its contribution to climate change, is 23 times more potent then carbon dioxide (CO2).

Some of the contributing factors are:

The world’s 1.5 billion cows and billions of other grazing animals emit dozens of polluting gases, including lots of methane. Two-thirds of all ammonia comes from cows as well. Cows emit a massive amount of methane through belching, with a lesser amount through flatulence. Statistics vary regarding how much methane the average dairy cow expels. Some experts say 100 liters to 200 liters a day (or about 26 gallons to about 53 gallons), while others say it’s up to 500 liters (about 132 gallons) a day. In any case, that’s a lot of methane, an amount comparable to the pollution produced by a car in a day.

Another way is to look at the processes that go into agriculture:

To feed animals that will be consumed in the future, they need to be fed. That means energy needs to be put into growing crops that will feed them (water irrigation/storage, seed distribution, harvesting, processing and distributing). That energy in turn creates more emissions.

Also, a problem with the current form of industrialized agriculture used in developed countries, is that they tend to stick to a "cash crop" or non-indigenous crop. This means that more fertilizer and pesticides will need to be used to mitigate the soil depletion and lack of natural defenses by the plant/crop. Not only does the use of these lead to irrigation run-off that take chemicals and nutrients to larger waterways which then deposit into ground water supply or even the ocean. (the ocean is bad because it creates a hypoxic deadzone the kills all sea life in that area - http://lab.visual-logic.com/2010/02/agricultural-runoff-in-the-mississippi-river-basin-and-the-dead-zone/)

To summarize - the manufacturing processes of agriculture and use of pesticides and fertilizers, fuel and oil for tractors, equipment, trucking and shipping, electricity for lighting, cooling, and heating, along with emissions of carbon dioxide, methane, nitrous oxide and other greenhouse gases bumps the impact up quite a bit.

Lastly, land use effects the impact to air pollution as well. In developing nations, money for crops is at a premium - oppose to rainforest concentration. So as a result, clear-cutting of heavily forested areas is common which not only releases carbon contained in the plants and soil. But it minimizes the capacity of the larger trees and plants to absorb carbon.

at what time in the morning is the air quality best to practice pranayam daily?
