Environmental Sustainability
The concept of environmental sustainability focuses on the portion of the narural resources which are either renewable such as forests or finite e.g. minerals. Environmental Sustainability (ES) adds consideration of the physical inputs in production processes with particular emphasis on ecological life support systems which without humanity would cease to exist. To put simply environmental sustainability can be summarised as the “maintenance of natural capital”. Environmental Sustainability is a set of constraints on four major activities regulating the scale of the human economic subsystem.
1. The output rule
Waste emissions from a project or action being considered should be kept within the asimilative capacity of the the local environment without unacceptable degradation of future waste absorptive capacity.
2. Input Rule
- Renewables – harvest rates of renewable resources should be within regenerative capacities of the natural system.
- Non renewables. Depletion rates should be set below the rate at which renerable substitutes are developed by human interventions and investment.
3. Operational principles
- The scale of the human ecoonomic subsystem should be limited to a level which is within the carrying capacity and therefore sustainable.
- Technological progressiuon on sustainable development should be about efficiency increasing and not throughput increasing.
- Renewable resources should be exploited on a profit optimizing, sustained yield and fully sustainable basis.

Environmental sustainability refers to the various techniques, processes and procedures implemented to protect the earth and its surrounding atmosphere. Environmental sustainability is mainly the natural method and processes carried out by the earth to make the earth itself rich in energy and natural resources. These various processes are a principle of cycle and recycling method done by earth to make the earth clean and free from water pollution as well as noise pollution. The earth itself has been able to achieve many recycling methods from the time since it came into existence. The earth’s atmosphere is rich in different types of gases like oxygen, nitrogen, hydrogen. All these gases have different purposes and requirements for cycling and recycling processes and even human existence. The human existence has evolved the emission of poisonous gases like carbon dioxide and carbon monoxide into the atmosphere because of the industries, automobile and apartments built for comfort, business and leisure and making money. But the earth has been able to control all these hazards automatically by taking in the carbon dioxide with the help of plants and trees and forest.
This type vegetations give out excess oxygen which is required by all living things for their existence. This process being adopted by the plants is called photosynthesis process. The earth makes the water available for living beings with the help of rain, river, lakes and ponds etc. During the summer the atmosphere takes in almost all the water content in firm of moisture and water vapour and all these content collected by the earth’s atmosphere is poured to earth in form of rain. But sometimes the rain poured becomes excess that it causes calamities like drastic flood. It is a natural recycling process.
