Answer 1

the presence in or introduction into the environment of a substance or thing that has harmful or poisonous effects.

Answer 2

you cant do this you got 6 questions all big ones

just ask one question

i will answer what kinds of polution there are

WATER POLUTION

FIRSTHAND CONTAMINATION

Rivers and Lagoons

millions of batteries are thrown in the rivers and Lagoons by night fishermen

1 small penlight battery contaminate 10.000 litres of water

raw sewage added to water flows like cannals and rivers ,

trash dumped on rivers edges ,

Industry contaminates practically unchecked

farmers using agro chemicals (fertilizers ,herbicides & pesticides)then deforrest and the rains washing the topsoils impregnated with contaminants into the rivers

thousands of women that do the washing in rivers using harmfull detergents.

farmers dump acidic coffee husk into the waters which kills millions of fish ,

on the coasts

oil spills that contaminate coastal waters,

Oceans

industrial wastes that are dumped into deep oceanic trenches

SECONDARY POLUTION

changes in water temperature enhances harmfull algae,(remember the red tide)

and kills many fish who are critical to temperature ,when sea water enters lagoons here in Mexico many fish die ,due to sudden temperature changes

also warm water releases carbon gasses

cold water absorbs them

SOLUTIONS

wetlands like swamps have always been Natures natural filters for natural water flows,aquatic plants clean the water ,the anchored plants as well as the floating ones

we should redesign wetland flora with in natural water systems to help contra contamination.

stop sewage systems that connect to natural water flows ,forbid and police the dumping of rubbish on waters edges ,

the best way is through the educational systems ,starting at kiddy schools and rising in intensity with progression.

but in Mexico this is not accepted because this kind of education is not in the ciriculum.

In short the ways to protect the waters is

laws and punishment ,government vigilence ,education ,

alternative farming methods away from using chemicals ,which eventually end up in the ground water supplies

to merely clean polution or try to clean is never effective because of population growth ,it gets worse by the year ,an impossible task

we must attack at the roots and that is the contaminating mentality

SOIL POLUTION

MONO CULTURE PLANTING EXHAUSTS AND CONTAMINATE THE SOIL

all plants and trees require certain chemicals and secrete others .

if there are too many of one specie ,the requirements are too much of the same and the soil gets exausted.

also if there is too much of the same chemical output the soil gets poluted,

and so bio diverse systems are always the healthiest

So agriculture polutes the soil apart from that this kind of farming uses pesticides ,herbicides and fertilizers,

because to much of one specie also attracts to much of one specie of preditors and disease,and is combatted with chemicals and too much of the same chemicals are demanded by the soil

on top of this heavy machinery is used which compacts the soil raising the salt content to the surface ,

the plough opens the top soil and this dries out .leaving it vulnarable to wind and water erosion (the dust is easily blown or washed away) and all micro organisms needed to build the soil are killed

so the destruction of lands is not only polution

other poluting factors are contaminated rain .and contaminated ground waters because of landfills

and contaminated beaches because of oilspills and sewage outlets,

And in the cities people continue to mix organic wastes with their trash ,this is responsible for 70% of soil contamination

SOLUTIONS

the worst you can do is throw it with the trash

70% of contamination is due to organic waste that is mixed in with the garbage .

and it is just as bad in the sewer where it helps to breed rats and in the landfill it poisons the ground

and it is the easiest to take care of

o first of all we have to clasify trash at least keep the organic to one side ,like in a plasic bin with a lid

if you got a few meters of ground ,you only need 1 or 2 square meters in a shallow hole ,in the shade ,that you can wet now and again ,where you dump everything that is organic ,from toilet paper,bones vegetable cuttings ,eggshells,,dead bodies ,excrement ,and cover regularly with leaves to keep humid and to hide any smell

the worms will come and decompose the wastes truning it into beautifull blck soil for the garden of flower pots .

if you are in a apartment ,if you have a balcony get a big plastic bin drill some holes in the side and lid ,

and add a few buckets of sand now and again to put over the trash ,you should realt stir or move the stuff at times to airate it and ensure that the decomposition is overall ,keep moist

this rubbish does not get big very fast and the thing works for a long time with out getting full

got a compost heap in the garden for 6 years ,have added tons of banana poles ,and palm leaves at times tree trunks ,the mountain goes up and down and never seems to get any bigger ,the stuff rots and becomes a very fine black compost of high density

We need more vigelance and control and laws for municipalities ,industry and agriculture plus education for farmers,on sustainable farming

and educating the public in not mixing organic wastes with their trash

AIR POLUTION

the smoke from industrial chimneys,the smoke from any fire

the escaping gasses from spraycans ,the fumes from all internal combustion engines in the world ,all contribute to air polution

.we live in a closed system,polution that is produced in one place can end up on the other side of the world.

there are aircurrants continuesly moving all around the globe, and 5 miles up in the air is a layer which can hold things as big as frogs ,that have been picked up by super evaporation ,that can come down somewhere else.

On the North pole contamination has been found in the ice ,that could have come from Newyork,

if people burn plastics or tires the contaminated smoke will go up and join aircurrants that take it someplace else.

Answer 3

Acid rain - Rainwater that has a pH lower than 7.  Rain water is naturally slightly acidic because carbon dioxide dissolves in water making carbonic acid.

Other sources - sulphur dioxide, oxides of nitrogen caused by fossil fuel burning and natural sources such as volcanoes(SO2) and lightning (NOx).  The oxides react with rain forming sulphuric and nitric acid rain.

Reduce acid rain - you can't reduce natural sources.  Industrial sources can be cleaned (scrubbers in smoke stacks of factories that remove SO2 and NOx),  or broken down into less harmful pollutants (use of catalytic converters in cars).

Global warming is the term used to explain the increase in global temperatures as a result of human activities, mainly burning fossil fuels.  It is caused by increasing the concentration of atmosheric carbondioxide from combustion of hydrocarbons.  The carbon dioxide prevents heat radiation from escaping back into space so it acts a bit like a jumper around the earth.

Hydrocarbon - a molecule/substance that is made up of only carbon and hydrogen atoms.

Incomplete combustion - when there is a lack of oxygen

Hydrocarbon+Oxygen ->Carbon monoxide+water+carbon      (the carbon is unreacted fuel)

Complete combustion - plenty of oxygen available.

Hydrocarbon  + Oxygen --> carbon dioxide  + water

Any chemical substance that causes harm to the environment is a pollutant.
