-  Land pollution stems from many different causes, both natural and artificial ones :
  + For natural causes such as acid soil, salty soil.
 + the cause of artificial soil pollution is largely from human consciousness. Over use of fertilizers and pesticides on crops has accidentally caused the soil to become acidic, and soil fertility is lost.
  + Moreover, soil pollution is also partly caused by littering and trash is not properly disintegrated 

• 2. EFFECTS

-Degraded land: 
the land will acid, 
salty, 
 not usable
-Affect to agriculture: 
lack of nutrients 
affect the quality of agricultural products.
-Effects on human: 
skin diseases
cancer
respiratory disorders, birth defects.
- Impacts on the ecosystem:
changes the flora, 
reduces the productivity of crops
 disturbs the ecological balance, 
affecting the life of living species

• 3.SOLUTIONS

There are a number of actions that could be taken .Let me offer some solutions to this problem.
- Using fewer pesticides and chemicals in agriculture and find alternatives 
- Appling"3R" in life :reduce ;reuse and recycle
- Reforestation.

• power plants, manufacturing facilities, waste incinerators, furnaces and other types of fuel-burning heating devices (the burning of fossil fuels such as coal, oil, natural gas)
• agricultural activities (the use of insecticides, pesticides, fertilizers)
• deforestation, the need for pastureland and growing fields, the removals of trees
• waste 
• population growth, urbanisation

• Dust
• Wildfires
• Volcanic activity 

• damage crops, forests
• global warming:rising sea levels, melting of ice air pollution, directly contaminate the surface of bodies of water and soil, kill young trees + other plants
• acid rain, degrade water quality in rivers, lakes and streams, cause buildings and monuments to decays

• adopt laws to regulate emissions: 
• take public transportation instead of driving a car
• ride a bike instead of travelling in carbon dioxide-emitting vehicles
• install pollution control devices
• encourage the use of environmentally friendly energy sources campaigns
• replace gasoline-fueled cars with zero-emissions vehicles

- Air pollution is caused by many factors:
 Human activities:

 + Exhaust fumes from vehicles.
 + Smoke from factories.
 + Carbon dioxide from burning oil, coal, and gases.
 +Lack of trees.
 + Agricultural activities( the use of pesticides and fertilizers)

 Natural causes:
 +Volcano eruption
 +Forest fires
 +Dust storms 

-Air pollution is clearly alarming because of its serious consequences:                               + Stuffy atmosphere -> accelerated global warming   + Human respiratory and heart concerns 
+ Wildlife endangerment 

- There are a number of actions that could be taken:

+ Discourage private vehicles to decrease fumes    +  Raise people's awareness about the drawbacks of air pollution.                                             + Be mindful of energy consumption                  + Recycle                                           + Use renewable sources instead of non-renewable sources

• The first problem is Wastes from factories and industrial parks are discharged directly into the soil environment.
• Another problem is ineffective management and treatment of industrial waste.
• Garbage in the process of living is growing problem in most families
  
  

• Soil pollution is another form of land pollution, where the upper of land pollution or soil composition is damaged or becomes alterd. Chemical fertilizers lead to loss of fertile land for agriculture, forest cover,...
• Waste not properly treated lead to drinking water is highly affected by land pollution. 
• Effect Human: The land, when contaminated with toxic chemicals and pesticides, leads to potentially fatal problems like skin cancer and human respiratory ailments in particular.

• The most effective way to get the root of the problem is to reduce, reuse and recyle.

- Firstly, rapid growth of the population increases the number of vehicles and narrow roads.
- Secondly, traffic signals out of sync many times.
- Finally, too many pedestrians crossing not permit cars to turn.

- To our environment: traffic pollution is noise, dust, fuel and petrol emission into the air caused by vehicles participating in traffic, such as: motorbikes and cars.
- To our health: when vehicles use fuel to operate, the engine will emit a large amount of toxic gases that pollute the environment and directly affect the health of people.

 - We should limit to use the vehicles which run by petroleum or fossil fuels. 
- Instead, we can ride bicycles to protect the environment.
- Moreover, we can use the vehicles which run by electric, and it’s also a good idea for environmental protection.

• - Large traffics in rush hour or after big events
• - Traffic accidents/Road construction/Mechanical failing
• - Bad weather: snow, heavy rain

• - Make people late for school and work and exhausted
• - Cause air pollution: more exhaust gas
• - Road rage

• - Use public transportation: buses, trains
• - Avoid travelling in rush hours
• - Upgrade the infrastructure: widen roads, build bridges and parking lot
• - Enact policies to limit private vehicles usage
• - Apply administrative sanctions to people who violate the law

• Overusing chemicals and pesticides in agricultural activities
• Littering improperly
• Urbanizing

• Spoiling water and soil
• Leading to climate change
• Endangering wildlife species
• Causing health problems: cancer, infectious diseases

• Using biological pesticides and fertilizers in agriculture
• Reforesting to improve the quality of land
• Developing Industry sustainably
