Tunguska was a thermal stress explosion of an asteroid or comet in the earth's atmosphere, most likely a comet as no ground debris could be found later. It is now believed that a nearby small lake is the impact crater for the remaining core after the explosion. It happened in 1908.

The def. of troposphere is: The lowest densest part of the earth's atmosphere in which most weather changes occur and temperature generally decreases rapidly with altitude and which extends from the earth's surface to the bottom of the stratosphere; adding IC on the end of that word makes it an adjective. Therefore we are talking about AIR pollution!

yes

If a person could eliminate crime or pollution, they should choose pollution. Pollution in the air can affect the lungs and may cause people to get sick and die.

can

They havent they helped and created Power Plants that create emission

Pollution forms on beaches by people who don't care about the environment and leave their trash wherever they want even if something could die from it!

no extra water

the 1L of water can be filtered through sand and activated carbon to remove some pollution, or it can be purified by evaporation and recondensation, or by chemical methods such as precipitation, without using any extra water

It is when the private marginal benefits or costs are not equal to social marginal benefits cost. Therefore, result could be likely market failure.

You can plant trees. It helps a lot.

Organisms in streams need oxygen to live when lacking dissolved oxygen it will kill these organisms. edit: unless the organisms in the stream are photosynthetic, in which case they will increase the oxygen levels. however, by far, most organisms in a stream are not photosynthetic and oxygenation occurs solely through aeration and surface area dissolving from the air. so, to answer the question, organisms (most organisms which aren't plant-based photosynthetic organisms) decrease the amount of oxygen in a stream. edit: a flowing stream has turbulence which helps aerate the water, increasing dissolved oxygen. In contrast, stagnant water tends to be low in dissolved oxygen, except near the surface. Multicellular animals (like fish) need a good supply of dissolved oxygen to thrive.

one substance that pollutes the air

i think tht ethanol, being a saturated hydro carbon, reduces the amount of soot or pollution produced. u probably know tht saturated hydrocarbons burn without soot and are more efficient when combusted. hope this helps. this is just what i think. :P

Particulate matter and ozone.

Deforestation, pollution, and habitat destruction all have human beings in common. Humans are destroying forests to build housing areas and cause the pollutionÊwhich in turn destroys animal habitats.

If it isn't today, then it certainly will be soon.

Some things to help to minimize noise pollution are... *Get a muffler for outdoor equipment (lawn mower, leaf blower, car, chainsaw, ect.) *Rake leaves by hand, don't use a noisy leaf blower. *Trim bushes or shrubs by hand, don't use a noisy bush trimmer. *Sound proof rooms that might have music conducted in them, like a room with a piano or if someone in the hosue plays drums or guitar or whatever. This can be done simply with curtains, window inserts, carpeting, and closing windows and doors. *Don't blast music on the radio or computer or speakers. Be considerate of your own ears and those of other around you. *Don't slam doors / car doors, close them eaily and with only as much force as needed. (People don't usually think of this, but imagine - how loud is it when you slam your car door? Pretty tolerable. But imagine thousands of people doing so. Now that can start to get loud. *Turn off the TV or radio when you aren't actually fully listening to it. *Train your dog not to bark so much. *Don't yell. Have civil conversations. Call someone or go find them instead of yelling across the street for them, for example. *Plant trees and bushes around you house. They help keep the air clean, absorb sound, give privacy, and add nice design and looks to a house. *Do noisy things (dishes, hammering, ect.) over or on a rubber mat to reduce noise. *Put carpets, rugs, mats, throw rugs, ect. in your house / mats outside. *Put fabric window coverings instead of plastic or wooden shades / blinds. *Don't rev up a motorcycle or car unless it is actually needed for the drive. *Don't beep your carn horn "just because", make sure it is a legit cause.

Natural gas is poisonous to humans therefore a foul smelling perfume is added to it to aid in the detection of gas leaks.

CO2 is a normal byproduct of human life. Our bodies use oxygen to create energy during aerobic activity (with oxygen) and then our bodies produce CO2 due to this activity. The blood takes the CO2 from our cells to the lungs, and then while the blood is picking up more oxygen, it dumps the CO2 so we can exhale it.

Since we exhale CO2 with every breath the gas itself does not cause harm to the structure of the lung. However, we cannot sustain human life without taking in oxygen and breathing out the resulting CO2.

If we were to inhale CO2, we would deprive our bodies of the necessary oxygen and in a short period of time would pass-out. Continued breathing of CO2 would eventually cause respiratory and/or cardiac failure.

It has killed many animals and has poluted the ocean alot!
