Why is Antarctica so easily polluted?
Antarctica is the most pollution-free continent on earth. The air is so clear that humans used to judging distances through polluted air cannot judge distance in Antarctica. For example, mountain peaks that are 30 miles away appear to these humans, to be about 70 miles away.
Antarctica is the least polluted continent on earth. In fact, there is so little particulate in the air, that there is no indoor dust.
Freshwater lakes supply most cities with drinking water. Industries also need lakes to survive. Large lakes affect the climate of a place, and are an important source of fish, waterfowl and fur bearing animals that live on their shores. Many lakes are man made and they are used for producing hydroelectricity and also for irrigation purposes. Do you know Ohio, city in USA has only man-made lakes.
Lakes are one of nature's most beautiful wonders, and are great tourists attractions. People go to a lake for boating, swimming, fishing and ice-skating etc. Sadly lakes are used as dumping grounds for sewage and wastes from cities and factories, and this poses a serious threat to the ecology of the region. So it is very important for us to keep to keep our lakes clean as lakes are very useful to us in many ways.
How is river pollution affecting people?
It makes the soil rich and so that helps the crops grow. That means there is more crops for the people who live there and nobody will go hungry People from other places will then want to go to the niger river because it is so successful and a good place to live. There will also be more jobs so people will not go jobless and more money will be made because they will sell the crops or food that they do not need.
How much of the Atlantic ocean is polluted?
All oceans have been polluted in some way, shape, or form. Oceans have been polluted be agricultural runoff and the dumping of garbage.
How is Mexico City trying to stop the pollution?
Yes, but as you should know, it is a problem of gargantuan proportions. Trying to reduce waste and pollution generated by 114 million people is not easy task. Some initiatives would include:
- Reforestation of many areas and regions affected by indiscriminate logging.
- Benefits and aids to farmers who employ 'sustainable' or 'organic' agricultural practices.
- Projects intending to exploit Mexico's renewable sources while decreasing dependence on fossil fuels.
How does the energy flow through the rainforest ecosystem?
The primary energy sources of coal, natural gas, and petroleum oil.
Where in Europe is the worst case of pollution?
In absolute figures the most air pollution is caused by big and bustling industrial countries, so Germany (the biggest industrial country in Europe) comes out on top. But if you look at who creates the most pollution in relation to its industrial output (in other words: who has the 'dirtiest' industries) Bulgaria and Roumenia come out on top.
Ways to prevent river pollution?
We can prevent pollution in river water in many ways and some of them are as follows:
- not discharging untreated sewage and other industrial waste water into rivers
- not dumping solid wastes, garbage and medical wastes in river banks
- not using river banks as open toilets
- not disposing dead human bodies/animal carcasses in rivers
- not quarrying sand in river beds which is a key factor in river bank stability and erosion of banks
- not washing vehicles directly in the flowing river water
- and in many other ways according to the life style of local people
River pollution can be controlled by:
- Reducing agricultural run-off
- Preventing or treating industrial discharges
- Preventing or treating municipal sanitary sewage discharges
- Preventing or treating municipal storm water discharges
- Preventing or controlling resource recovery in river channels
- Controlling shipping (ballast, swage) discharges
- Controlling marina operations
- Most fresh water pollution is caused by organic material. Humans bring organisms from one body of water to another causing aquatic plants and animals to die. Littering, sewage, food waste and farm effluent also cause under water plants and animals to die.
- Some other kinds of water pollution are industrial waste, fertilisers, oil and warm water. If large amounts of fertiliser or farm waste drains into a river or lake, the algae uses these substances to grow rapidly, turning the water green. Chemical waste is sometimes discharged into lakes and rivers. Some of these pollutants include: cyanide, zinc, lead, copper, cadmium and mercury. If oil enters either a slow moving river or a lake, it causes the surface to turn rainbow colours which prevents oxygen from entering the water. Industry often uses water for cooling processes, sometimes discharging warm water back into rivers or lakes. Making the water warmer makes the level of dissolved oxygen lower.
If you pollute the rivers what will happen?
If we will pollute the rivers it will have a bad impact on environment, health, specially the life under water.
The river is a home to many animals. So by polluting this river you are slowly declairing war on their ecosystem and destroying it. All the fIsh and other wildlife that use that river for something will edvenually die out
Are the great lakes being polluted?
The pollution problems in the Great Lakes have traditionally been linked to discharges of phosphates, mercury, chlorinated organics, organic materials like phenols and dissolved solids. The phosphates were removed by the reformulation of detergents, the mercury by th elimination of this compound at chloralkali plants, the chlorinated organics by product reformation and tighter controls at manufacturing plants, organic materials by improved treatment and the dissolved solids by improved treatment and use controls. Oil spills although an ongoing issue are generally a surface phenomenon which care controllable.
Some organic problems due to invasive species such as sea lampreys and zebra mussels are being tackled by biocides.
In genral the water quality is greatly improved since the mid-1969s.
Was air pollution in Mexico City deadly?
Yes it is breathing in the air was like smoking to packs of ciggerattes a day
How is the yellow river polluted?
by the number of people throwing rubbish in it. it sometimes even turns red, which is not natural
Why is it so important not to pollute your oceans and waterways?
Because of the pollution we are throwing in to the water. The water is getting contaminated. So if you drink the water you could get very sick and maybe die. And it kills our food. It kills our fish and other aquatic animals. And if a cow or something else were to drink it would die too. And if the animals are all gone what will we eat? And if farmers put nitrogen chemicals on their crops, the runoff will run into rivers and then into oceans/lakes. The chemicals also will percolate (seep) into the ground and go into underground aquiffers. Farmers should just put cow manure on plants because cow manure has lots of nitrogen in it.
DECOMP, RUN OFF FROM ROADS AND SEWAGE, ALSO ANIMAL URINE AND CRAP
What are the problems in the great lakes that deal with pollution?
. Zebra Mussels, which are a small striped freshwater mussel from NE Europe, have been steadily invading America's rivers and lakes. They can attach themselves to any surface which includes water pipes; water pipes can easily be clogged up and with a couple hundred Zebra Mussels which can cause a big problem. Zebra Mussels lay anywhere from 30,000 to 1 million eggs each year, that's a lot of Zebra Mussels! Zebra Mussels deposit pollutants as pseudo feces, pollutants of mucous mixed with particulate matter that they filter from the water. Scavenging animals that eat the pseudo feces may pass these pollutants up the food chain.
There can be many different reasons
1. The ocean has a lot of currents
2. Some oceans are very cold
3. There can be sharks or jellyfish
4. The ocean is very deep
What is the five most biggest ocean in the world?
#1 The Pacific Ocean 155,557,000 sq km #2 Arlantic Ocean 76,762,000 sq km #3 Indian Ocean 68,556,000 sq km #4 Southern Ocean 20,327,000sq km #5 The Arctic Ocean 14,056,00
How runoff water can pollute a river or stream?
runoff can pollute a river or stream because when the water flows over the ground, it could pick up some trash or garbage on the ground, and the garbage could flow with the runoff. Then when the runoff enters a stream, lake, or ocean, the garbage will flow into the water, causing pollution.
How much pollution in the orange river?
the Vaal river is connected to the Orange River and the Orange River itslef isnt polluted, but since the Vaal River has acidic water, the Orange River will be polluted.
The oceans of the world are essential to:
- the removal of carbon dioxide
- the production of oxygen
- the production of food
the addition of heavy metals like lead or other pollutants can interfere with all of these functions and mankind would suffer.
What are some causes of pollution in the Yangtze River?
it has a big affect of the agriculture and harvests and if it reaches the human water supply it could have serious
consequences.
