What is the environment?
environment
* The environment is a combination of living, inanimate, and physical elements that undergo changes that affect the organism.
* Environment is called Environs in English. Environ in French means surrounded.
Types of environment
1. Physical environment: The physical environment is called the natural environs the inanimate environment. Land, water, air, a climate that affects the ecosystem Etc. physical aspects. Climate factors such as rainwater, sunlight, humidity, pressure, and wind speed are also factors.
2. Biological environment: It is also known as the living environment. It helps the survival of the organism. Earth’s animals, humans, flora, birds, aquatic organisms, and microorganisms are integral parts of the biological environs. The environs can be divided into two types based on human involvement. They are:
1. An artificial or man-made environment
2. Natural Siddha environment

Ecology,
* Ecology is the science of studying the relationships between living things and their surroundings.
* Ecology The term nuclear is called ecology in English.
* Heckel defined ecology as the study of the interactions between organisms and their inanimate environment.
* The term ecology was first used by the scientist Carl Reiter in 1868 and was popularized in 1869 by the scientist Ernest Heckel.
* The study of ecologically active activities is called ecology e. P is defined by Odom.
* Father of Indian Ecology -R. Mishra, the father of modern ecology e. P. Odom.
* Intrinsic relationships between different species in different parts of the ecosystem, their relationship to the environs, and their functions, habitat, and reproductive processes. Mishra, a scientist, claims that ecology is the science that is studied in terms of.
Environmental pollution
* Undesirable changes in the environment’s physical, chemical, and biological properties are called environmental pollution.
* Definition given by the Indian Environmental Pollution Act, 1986: Any unwanted substances in solid, liquid and gaseous states should not be allowed into the environment beyond the limit Environmental pollution is a condition that interferes with the survival of humans and other organisms due to their involvement and alteration of their natural environment.
* The word pollution is derived from the Latin word plutonium. This means uncleanliness.
* Pollution poses a danger to all living things. Pollution can also cause physical erosion.
Types of pollution
* Environmental pollution is classified as follows according to the changes it brings in environmental factors.
1. Air pollution 2. Water pollution 3. Soil pollution 4. Noise pollution 5. Heat pollution 6. Radiothermal pollution
Pollution factors
1. Biodegradable but pollutants: These do not decompose in nature. Or slowly break down. These are known in the environs and cause pollution.100 Remain in the same condition for years and cause harm to the environs. Eg: Aluminum cans, plastic, polyethylene, etc.
2. Biodegradable pollutants: Decomposition factors by the influence of environmental decomposers. E.g .: garbage, vegetation, animal remains, sewage, paper, leather, etc.
3. There are two types of pollutants based on the changes that take place after entering the environs.
* Primary pollutants: Contaminate the environment in the same condition as it was before it was released into the environs and even after it was released into the environs. E.g .: Mercury, DDT, etc.
* Secondary pollutants: Major pollutants are new substances formed due to chemical changes that take place after their release into the environs. E.g .: sulfuric acid, Nitric acid, nitrate, and ozone.
