The main principles of international environmental law are: 
1.
State sovereignty over natural resources. 
2.
States shall not harm the environment outside their jurisdiction. 
3.
The advantage of human environmental rights. 
4.
Management of environmental control at all stages. 
5.
Freedom of exchange of environmental information. 
6.
Mutual environmental consultation. 
7.
Mutual assistance of states in case of ecological crisis. 
8.
Peaceful settlement of legal and environmental disputes. 
Solving environmental problems through sustainable development. 
Sources of environmental pollution. 
Sources of pollution can be divided into two groups: 
natural and 
anthropogenic. 
Natural resources: 

alkalinization of rocks; 

underground gas, water and oil products (radan and methane); 

Impulse sources (volcanic eruptions, landslides, floods, landslides).
Anthropogenicsources: 

miningand transportation of minerals; all types of industry and transport; 

agriculture; 

domestic sectors; 

wars; 

emergencies. 
Natural pollution is generally more intense, but aitropogei pollution is dangerous 
at the expense of its harmful and active components. 
Types of natural pollution: 
1.
Chemical – an increase in the average amount of perennial changes in the 
natural environment and changes in the composition of chemicals during 
the period under consideration. (oceans, forests) Classified by hazard 
(Class 1 is the most dangerous). 
2.
Physical – pollution caused by changes in the physical parameters of the 
environment. 
The manifestations of physical pollution are: 

Radiation – is the excess of radioactive substances over the natural 
content of Anrsoka. 

Light – darkness, which can disrupt the natural illumination of places due 
to the influence of artificial light sources, which can have an anomalous 
effect on the flora and fauna. This includes laser radiation [4]. 

Thermal – thermal air, exhaust gases and heat from industrial production; 
changes in ambient temperature at the expense of water.


Noise (acoustic) – occurs due to the fact that the intensity of the noise 
exceeds the natural level. 

Biological – bacteria, viruses and other biological compounds that 
adversely affect the flora, fauna and fertile soil layer of the ecosystem. 
Pollution control methods. 
All control methods can be divided into two groups – direct environment and 
remote control methods. In turn, these methods are divided into observation and 
instrumental (measuring instruments). 
The remote monitoring method includes measuring instruments above 2 m 
above the ground. In recent years, remote monitoring is widely used, especially in the 
field of environmental control of large areas (region, republic); ecological condition 
in medium-sized areas (cities, districts). 
These include air flow, water quality and agrochemical laboratories, among 
others. Control of environmental pollutioniipptp is a key component of natural 
environmental management. 
The object of international law for the protection of the environment – natural 
objects that are the subject of environmental relations of the subjects of international 
law, that is, in terms of their nature, location and importance are not under the 
jurisdiction or control of any state natural elements that do not exist and are therefore 
the property of two or more countries or subjects of international law. 
Examples are the Amudarya and Syrdarya rivers. They are, by their very nature 
and importance, the subject of environmental law. However, the use and protection of 
the two great rivers is not limited to the Republic of Uzbekistan. Because these rivers 
start in Kyrgyzstan, Tajikistan, Afghanistan and flow through the neighboring 
republics of Kazakhstan and Turkmenistan. Pollution of the upper reaches of these 
rivers or changes in water regimes will, of course, have a negative impact on the 
lower states through which they flow. Therefore, the use and protection of such 
facilities is carried out through sources of international law. 
International environmental organizations. 
Environmental organizations, institutions and agencies that aim to protect the 
environment and the efficient use of international natural resources, which is one of 
the universal values, are divided into universal and regional (regional) types 
according to their scope of activities. 
Universal International Environmental Organizations are international 
organizations of various categories, political, social and economic development, as 
well as the regulation of environmental relations of countries in all regions of the 
world. They include the UN and its specialized agencies. 
International environmental responsibility. 
Environmental liability of subjects of international law is harmful or unlawful 
actions, actions or omissions that contradict the protection of the environment 
resulting from their economic, social, military, technological, recreational and similar 
economic activities.

International environmental law liability – to the subjects of international law 
arising from the use of international environmental objects to compensate for damage 
to the environment through the abuse or violation of universal, regional and 
international law established between the two countries; compulsory experience of 
unfavorable material and political conditions applied or their legal punishment. 
Unfavorable material liability or material liability is defined as financial 
(reparation), natural (restitution) or replacement (substitution) of damage caused to 
ecologically damaged states or ecological objects not under the jurisdiction of states 
(through international environmental organizations). understand the coverage.
