safety regulations for dishes in a hotel or restaurant 2017 List of Environmental Problems
The Earth's environment has become a universal global problem.
The Earth's environment is in a state of regret and there is no hope that it will soon become better.
People are increasingly aware of the need to protect the environment.
There are many environmental problems that affect our planet.
No matter where you look, you will encounter various forms of pollution.
The forest is disappearing.
The green space around the city is being replaced by concrete buildings.
Dumping waste products without distinction.
The water is too toxic to drink.
The air is not suitable for breathing.
Global warming has become a threatening problem.
This article is designed to give you an idea of as many environmental issues as possible.
To facilitate the understanding of these problems, different problems are divided into four categories.
You may jump to the category you are interested in.
People worry about how long life on Earth will survive.
Human beings are on the verge of self.
Caused a disaster.
Indeed, there are too many environmental problems today.
Any gas in the atmosphere that absorbs and emits radiation within the thermal infrared range is called greenhouse gases.
The greenhouse effect is a process through which heat radiation from the surface of the planet is absorbed by the atmospheric greenhouse gases and reabsorbed
Radiation in all directions.
This process repeats over and over again, capturing radiation in the atmosphere.
This is one of the main reasons for global warming.
Global warming has caused the Earth to lose snow;
Glaciers are melting, the sea
Flowers and animals in the Arctic are on the verge of extinction.
Since the 1980 s, the ozone cladding around the Earth has been heavily consumed.
This is largely due to the influence of halogen-substituted carbon refrigerants (such as CFC, halon, Freon, etc. ).
Halogen hydrocarbons (lighter than other gases in the atmosphere) rise higher in the atmosphere.
Then, they are carried out to separate and produce atomic halogen.
These atoms catalyse the destruction of ozone gases.
The depletion of the ozone layer is a threat to human and animal life.
The ozone layer protects us from the ultraviolet rays of the sun;
Without ozone, everyone is prone to multiple skin diseases, including skin cancer.
The air quality we breathe is getting worse.
This includes air quality outside our home (outdoor air quality) as well as indoor air quality.
In fact, indoor air quality has been designated as one of the most serious environmental problems, especially in urban areas.
Government agencies usually set values for different gases and components in the air at certain levelsso-
Harmful/harmful inhalation;
These values are called the air quality index (AQI ).
The air quality index (AQI) helps to monitor air quality.
The main reason for the deterioration of air quality is air pollution.
Air stagnation (due to lack of wind, temperature reversal, etc ).
) Is another important reason.
Poor air quality can prevent children and the elderly from carrying out daily activities and even walking out of the house.
Poor air quality can also make you feel tired and tired all day, no matter what diet you follow or how much sleep you have.
Air pollution can be one of the most dangerous human effects on the environment because we cannot control the air we breathe (although we may be able to control the quality of drinking water, food, etc. ).
The smoke generated by the smoke emitted by vehicle traffic, vehicles and factories, the aerosol (suspended particulate matter), VOCs (volatile organic compounds) mainly present in paint, varnish and refrigerant are all reasons for air pollution
Air pollution affects everything.
It affects plants, animals and humans.
According to the World Health Organization, poor indoor air quality can lead to respiratory infections, coronary artery disease and even lung cancer.
If all this happens indoors, imagine what happens outside.
Gases such as carbon dioxide, nitrogen oxides and sulfur dioxide can react with water to produce corresponding acids.
When this happens in the atmosphere, we get rain water with acid pH.
These gases are released into the atmosphere through natural processes such as lightning and volcanoes.
However, due to factories, vehicles and different industries, the emissions of these gases exceed those naturally generated.
It goes beyond what nature can tolerate.
Rain water can corrupt stones, rocks, steel and other types of corrosive metals;
The paint will also fall off from the surface exposed to this destructive rainfall.
This means that monuments, statues, bridges and buildings are in danger.
At the current rate, there may be a time when people will not be able to get out of the house because it will cause damage to the skin.
People cannot really control or prevent the production of waste water.
However, due to the human impact of human development, the composition of wastewater is changing every year, so more and more materials cannot be treated are added to wastewater and eventually added to water.
If the number of these substances increases, they accumulate in the food chain.
If effective management is not carried out, the management of wastewater will eventually affect various life forms.
Enrichment and division (discussed below) is a serious consequence of low and/or inadequate wastewater treatment efficiency. Urban run-
Off is the flow of rain from land into water.
This is a natural process.
However, with any time before
With the acceleration of the urbanization process, this process has had an adverse impact on the water body because
Now, off carries a variety of compounds, chemicals and particulate matter.
In the case of abundant trees and vegetation, the total amount of rain water entering the water body is only about 10%.
But this amount has increased nearly five times! Urban run-
Deposits of oil, gasoline, garbage, heavy metals (nickel, copper, lead, zinc, etc.
), Fertilizers, pesticides (from gardens and lawns), synthetic organic compounds, etc.
All of this ended up in the food chain, leading to many health complications. Urban run-
It also partly leads to nutrient-rich water bodies.
Generally speaking, rich culture and division refers to the excessive growth of plankton in water bodies.
Almost all natural water bodies (unless intentionally protected) are affected by water pollution;
This adds some "Substrates" such as phosphate, nitrate, sewage waste, etc.
Go to the water.
All these substances promote the growth of plants.
A growing plant) to this extent, it completely drains the oxygen and other nutrients in the water body.
Algae Hua is one of the effects of rich and differentiated water bodies.
Oxygen depletion (or lack of oxygen) can lead to the death of many fish and other forms of aquatic life.
On the other hand, it may lead to an increase in the number of bad aquatic species, thus completely breaking the natural balance.
When the amount of water in a region does not meet the needs of all life in the region, this situation is called the water crisis.
The shortage of water is the main cause of the water crisis.
This shortage has occurred for some reasons, including waste of water, deforestation, urbanization, etc. Water-
Spreading disease is the leading cause of death worldwide.
Drinking water is unavailable to 9 million people worldwide.
Sudan and Venezuela are the regions with the largest number of water crises. Water is life.
There is no life without water.
Marine pollution is not so much a problem as a consequence;
The different reasons are low efficiency and/or inadequate wastewater treatment, urban operation
Closed, rich nutrition, etc.
In addition to this, solid materials, especially plastic, cause great trouble.
Ocean acidification, on the other hand, refers to the effect of human carbon dioxide on the pH of the ocean.
The last thing we want is pollution.
Ponds, lakes, wells and rivers are still controllable;
However, once the ocean is irrevocably polluted, it will bring bad luck to all life on Earth.
The culprit of many environmental problems is that we are not aware of how many factors contribute to a huge problem.
We always think that we have so much water and land that we can't run out.
The Earth is huge!
But there is a difference between seawater and available water;
Between any land and available land.
The amount of usable land we have is rapidly decreasing.
There are many purposes for our use of the land, most of which are abused.
Use too many good things and you will definitely waste some.
Low efficiency of land use is dominant
Related environmental issues
The low efficiency of land use is three main problems: urban expansion, habitat fragmentation and habitat destruction.
The spread of cities is the trend that cities and suburbs spread and Occupy to the suburbs of a certain area.
The biggest reason is that we are not using the land we have effectively.
On the other hand, the most serious consequence of urban expansion is the rise in car prices.
Relying on development, which makes the car
It leads to more fuel consumption, more air pollution, and some other things.
The consequence of urban expansion is the impact on human health as a whole
The longer the commute distance each day, means that the longer the travel time, the lower the work efficiency, the more boring social life, the less social interaction (because everyone is too busy), the tension in interpersonal relationships, even psychological problems.
Human activity has resulted in land being divided into different areas, thus destroying the habitat of the living creatures.
To put it simply, when urbanization erodes the forest, wildlife experiences habitat fragmentation.
We have other places to go if we don't have land.
However, in order to create more space for ourselves, we are depriving wild animals of their habitat and they have nowhere to go.
Many species are endangered by habitat fragmentation.
In order to make room for agriculture and housing, the local vegetation was destroyed.
However, many plant species are facing extinction in the process.
More or less hands-in-
With the fragmentation of habitat, it can be called the final effect of excessive habitat fragmentation.
The biggest reason for habitat destruction is to clean up the land for agriculture.
Many of us don't even know that land conversion is an outrageous crime!
The biodiversity that was once lost is irreplaceable.
It may sound mellow to you, but if a species disappears, it means that the food chain becomes more unstable.
To give a simple example: if the snake is extinct, the mouse will cause havoc!
But rats and mice could be the next invasive species!
Although we have to take on great tasks, we can still correct the problem of inefficient land use.
However, a piece of land that cannot be repaired has been destroyed and we have lost forever a future school, hospital or church.
When an ordinary land is converted into a desert, a desert will be formed.
For me, this is one of the most terrible prospects for human development;
Turn beautiful gardens, parks, forests into deserts!
Do you know that 2 billion people actually live in dry areas?
In addition, drought accounts for more than 40% of the earth;
We are adding confusion through our actions.
One of the most serious examples is Lake Chad in Nigeria.
The lake has shrunk a lot and lost 95% of the area!
Land pollution is mainly caused by low and/or inadequate waste disposal efficiency, increased mechanization and excessive use of fertilizers and pesticides in gardens and farms.
All of these reasons have a unique impact.
Put them all together, we are actually tormenting our own land with our hands!
Filling in and littering is like stuffing bad food into your drum because you can't find a bin to throw it away.
Soil pollution is a part of land pollution, but in the form of poor quality of agricultural land, the consequences are even more serious.
Rainwater collects and deposits all land pollutants into water bodies, so there are two
The entry of pollutants in our food.
In addition to this, these chemicals not only hurt us, but also adversely affect all biological forms.
In fact, this is especially true of wildlife and plants.
We can still find a way to get the spoiled water to drink, but what about animals?
When low efficiency of resource use leads to a shortage of related resources, resources are exhausted.
Some of the main reasons are excessive.
Population, land conversion, pollution (air, water, land, soil, etc ).
), Waste of resources and excessive wasteconsumption.
Factors such as human development and other activities (mining, logging, factories and industries, intensive agriculture, deforestation), and consumerism, in turn, are the causes and effects of inefficient resource management.
Because of the human impact of almost all of our actions, there is clearly no protection.
This in turn drives more and more species such as animals, birds, plants, etc.
Enter the "endangered" section and face extinction among non-endangered speciesso-distant future.
Without its predators, the number of prey may increase to such a degree that it destroys the balance of nature and destroys the normal ecology of the niche in which it exists.
Neither of these situations can be dealt with positively. Two words -
Plastic and electronic waste.
These are two kinds of environmental problems that we can handle.
The two best ways to avoid plastic build-ups are not to buy packaged water and not to use plastic bags.
As far as I am concerned, this principle is strictly followed.
As for electronic trash, think twice before burning a DVD, discarding an old phone and buying a new phone, buying a new camera, iPod or PlayStation;
Actually, think more than twice.
Anyone who has read a newspaper (or at least someone who has read it) must be aware of the GM food and its controversy.
Everyone praised Dolly's success (the first animal to be successfully cloned, a sheep.
However, if you see Dolly's clone and you're scared, it's a big mistake.
There is no way to "discard" or "throw" errors or unwanted genetic operations.
The most terrible prospect is disease.
Due to the excessive use of drugs, microorganisms are resistant to drugs.
Changes at the genetic level are permanent;
Although we try our best to eliminate the bad effects, the good ones will inevitably have some adverse effects.
This is a topic that has been discussed for quite a long time.
Radiation is probably the deadliest of these.
They don't just affect you.
They also affect your children and their children.
Personally, I think the most shocking aspect of nuclear development is the potential nuclear accident that could happen.
There is no need for another Chernobyl disaster;
We do not want another city to face the same fate as Hiroshima and Nagasaki.
The most serious challenge or urgent need of the moment is the ability to accurately monitor and evaluate the effects of nanoparticles.
This is especially difficult because the material changes its properties and behavior at the "nano" size.
Therefore, these issues should be viewed from different and new perspectives;
This is especially true in medical applications.
The toxicity of nanoparticles needs to be evaluated and scientific research carried out.
The root of all sin.
The problem with dealing with and talking about the population explosion is that we do not look at it objectively.
At a particular moment, emotions and emotions are mixed with the practicality of this argument;
This is where we lose all our perception.
However, one should look at the population explosion like any other issue and treat it as strictly and seriously as any other issue.
Before humans reach the point of no return, these and many more important environmental problems need to be solved on the basis of war.
Only the participation and cooperation of the entire international community can provide a clean and safe environment for the future.
