Landscape ecology

Community ecology

Population ecology

Global ecology

Molecular ecology

Molecular ecology can be defined as an area of evolutionary biology which examines the dynamics of ecology on a molecular level.

Molecular ecology tries to answer several genetic-based questions regarding ecological evolution.

Ecosystem ecology

Ecosystem ecology can be regarded as a field of study related to biotic and abiotic components and their interactions within an ecosystem framework.

Organismal ecology

Organismal ecology tries to study how individual organisms interact and respond to changing environmental factors and environmental challenges.

Landscape ecology

Landscape ecology studies the relationships between particular ecosystems and ecological processes in the environment.

Key topics of landscape ecology include land use and land cover change and ecological flows in landscape mosaics.

Community ecology

Community ecology examines the interaction of two or more populations living in the same geographical area.

Air Pollution
Pollution is now a commonplace term that our ears are attuned to. We hear about the various forms of pollution every day and read about it through the mass media. Air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside.
A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. It occurs when any harmful gases, dust, smoke enters into the atmosphere and makes it difficult for plants, animals , and humans to survive as the air becomes dirty. The sustainment of all things living is due to a combination of gases that collectively form the atmosphere; the imbalance caused by the increase or decrease in the percentage of these gases can be harmful to survival.
The Ozone layer considered crucial for the existence of the ecosystems on the planet is depleting due to increased pollution. Global warming, a direct result of the increased imbalance of gases in the atmosphere, has come to be known as the biggest threat and challenge that the contemporary world has to overcome in a bid for survival.
When we try to study the sources of Air pollution, we usually enlist a series of activities and interactions that create these pollutants. There are two types of sources that we will take a look, namely Natural sources and Man-made sources.
Natural sources of pollution include dust carried by the wind from locations with very little or no green cover, gases released from the body processes of living beings (Carbon dioxide from humans during respiration, Methane from cattle during digestion, Oxygen from plants during Photosynthesis).
The major outdoor pollution sources include power generation, vehicles, agriculture/waste incineration, industry and building heating systems. Smoke features as a prominent component. The smoke emitted from various forms of combustion, like in biomass, factories, vehicles, furnaces, etc.
