Dear prof Sundus Abdulkariem Alabdulla

1- The main source of Pollution is Human & human activities and 2- In the future Human should back to the Green solutions and not turn a blind eye to this environmental issues any more !

The ecosystem and environment at present time is already contaminated with several organic and inorganic pollutants particularly in big industrial countries such as China and India .The main pollutants are as follow :

-Organic pollutants ,They are mainly pesticides particularly chlorinated hydrocarbon pesticides (DDT,lindane,cyclohexadienes e.g aldrin ,dieldrin,endrin ....etc) ,PCPs and unintentional compounds (furan and dioxene ).

-Heavy metals particularly mercury ,leads ,tins,copper .......etc.

-Fertilizers particularly nitrate and nitrete ...etc.

- Radiations such as uranium ,x- rays,electron rays,Beta rays..etc .

Plastic bags and sheets:those for agricultural ,industrial ....etc.

_Carbon oxides gases,nitrogenous gases,sulfur oxides and other gases ...etc.

-Climatic change such as increase in temperature .

-Ozone hole

I think for long run, many persons from heavy contaminated countries will migrate to other less polluted countries.Diseases particularly chronic diseases such as different types of cancers will be spread commonly in these contaminated countries .In addition ,difficulty in breathing is going to occur in such countries .Salam and best wishes .

Hi dear Sundus,

Source of environmental pollution vaired in fucntion of activities sector and in each sector we can have the majors sources of pollution. Moreover, its can varied in fucntion of the country because some countries have put in place policies for environnemetal pollution regulation others countries nothing.

In Africa, we can have for example pesticides, chemical fertilazers in Agriculture sector,

in forest sector, during logging we can have poorly managed waste oil which impact soil, CO2 produced by the machinery during logging, etc.

In agro-industries (biere, wine, etc.) or small or medium industries, we can have organic polluants which contribute to water pollution,

etc.

Simple and brief precise answer dear Dr Parisa, Thank you

Lust of power

This is an important question.It needs lot of ideas to cover all aspects of the question .Hope ,other researchers or readers are needed to contribute strongly .Best wishes .

all technological development to cause environmental pollution like e-waste, vehicle emission, nuclear waste, agriculture waste,sewage etc.

we have to reduce our over use of all sources for reduction of environmental pollution.

and turn to green technology

It is a good fruitful scietific discussioin .Best regards all .

The Anthropogenic factor is the main factor (Human). Unsustainable human activities, led to over-exploitation and destroying of the natural resources. Sustainable clean and green ways should be adopted in the future.

Industrial ,agricultural and medical wastes are briefly the main sources for environmental pollution .The solution is to go back to nature .Best wishes .

Hello Everybody

I think, The most important factors are contaminated including: Industries( Factories and ......) and Agricultural( Pesticides, Herbicides, Fungicides and .....) also, residual of pesticides and heavy metals in groundwater and rivers caused pollution of Aquatic and terrestrial Ecosystems So, We should provide stricter laws for both(Industries and Agricultural).

Agreed with you dear Samaneh in all ideas you raised about pollution . Best regards.

Assalam Dear Dr Al Antary

Thank u for ur attention

The industrial revolution is the main cause of pollution in all sectors,

In my opinion, plastic waste is one of the most hazardous wastes on land, sea and river biodiversity because of the long life span of plastic waste.

Plastic wastes have direct and indirect damage to all neighborhoods on the ground.

And agree with you dear Samaneh.

Best regards,,

Thank u Dr Riad

Also, i agree with u
