WD on gas = P x deltaV
WD by gas = negative of above
third law, I guess.

None of the above. The best is “Protection of the environment is being used as an agrument for globalization.”

So, formaldehyde, after breaking down in the environment, forms both formic acid and carbon monoxide, correct? Well, that’s what I found but I’m not sure the negative effects these two substances have on the environment. Any help? It would be much appreciated.

Best reply by Tgregoryt:

Not sure what your question is here but formaldehyde is more toxic then both carbon monoxide and formic acid. Formic acid is harmful in the air but I don’t believe it is significant in soil or water. Further, formic acid is not a by-product of formaldehyde weathering, having an additional hydroxyl radical. Carbon monoxide is similar, but it is not harmful in the air until is gets quite concentrated, and the dangerous concentration of formaldehyde in the air is significantly less.

Driving a car is the most air polluting act an average citizen commits. Air pollution is not a good idea for a variety of reasons, large and small. The right ideas for remediation of environmental degradations involve unselfish and compassionate behavior, a scarce commodity. The right ideas involve long-term planning, conservation and a deep commitment to preserving the natural world. Without a healthy natural environment, there will be few or no healthy humans. To understand air pollution you can consider a simple schematic that divides a big problem into components.

1. Local effects -e.g. poisoning humans breathing bad air.

2. Regional effects – fallout from airborne pathogens – infections, particles, chemicals.

3. Global effects – changing interactions between the atmosphere and sun, weather effects, effects on plants and oceans.

This one below, with all of the new roads being built, if it is paved over, plants cannot grow and provide oxygen to breath.
Infrastructure
Aside from industries, one of the most visible effects the automobile has had on the world is the huge increase in the amount of surfaced roads. For example, between 1921 and 1941, the United States spent US$40 billion on roads, increasing the amount of surfaced road from 387,000 miles (619,000 kilometers) to over 1,000,000 miles (1.6 million kilometers) which does not even take into account road widening.[2]

Motor vehicle accidents are attributed to 37.5% of accidental deaths in the United States, making them the country’s leading cause of accidental death.[

What are we doing to the environment and what are some of the positive and negative effects? If u find a site of info on “human activity in the environment”, plz list them. Thx in advance.

Best reply by Sherr:

Well some are as follows:
1. Cutting down trees.(Good: as wood for wooden products and paper) (Bad: destroys habitats of flora & fauna, causes landslides and upsets the balance of nature)

2. Over hunting.(Good: as food for humans) (Bad: makes animal species extinct and upsets the food chain)

3. Plantations replacing natural forests. (Good: to gain profit(money) for the country) (Bad: endangers various plant species and increasing carbon dioxide content in the air)

Those are some but if you want the full list, it’s endless.
