What is sustainable can be maintained by itself without generating a scarcity of resources.
Sustainable is something that can be supported or defended with reasons . For example: "Give me a sustainable reason not to fire Gómez" , "The judge considered that his explanations were not sustainable and decided to sentence him to life imprisonment" , "There is no sustainable reason that justifies such behavior" .
The concept is often used as a synonym for sustainable in the field of ecology . A sustainable or sustainable process is one that can be maintained over time by itself, without outside help and without causing a shortage of existing resources .
The importance of sustainable development
Sustainable development , therefore, allows current needs to be met without compromising the possibilities of future generations. This means that economic activities based on the exploitation of oil, to cite an example, are not sustainable since oil is a non-renewable good that will be exhausted sooner or later and causes damage to the environment .
In this way, thanks to this type of development, what is achieved are two fundamental things. On the one hand, there is a strong commitment to protecting the natural environment that surrounds us; and on the other hand, what is done is to achieve a better quality of life for citizens.
Wind energy is sustainable: it does not harm the environment and is not depleted since it comes from the wind.
Renewable energies
In this sense, the so-called renewable or green energies take on special prominence. They are those that are obtained through natural sources that have the particularity that they cannot be exhausted. In this way, for example, we find the so-called solar energy , which uses the Sun's rays to generate electricity through devices such as solar panels.
However, we must also highlight the existence of another important series of sustainable energies:
Wind . As its name indicates, it is that which is generated by the force of the wind.
Hydraulics . In their case, the energy is created thanks to waterfalls in rivers.
Marina . Closely related to the previous one is this one that is sustained by the waves and tides that arise in the different seas.
Geothermal or solar thermal are other types of existing green energy that have become a fundamental pillar of the different initiatives carried out throughout the world to achieve the long-awaited environmental sustainability . All of them are experiencing great growth because even in the most domestic sphere they are used.
Sustainability, the economy and society
Sustainable development must consider the economic aspect (the creation of wealth in all sectors), the social aspect (by taking into account the consequences of economic activity on society in general) and the environmental aspect (economic activity must be compatible with the preservation of biodiversity and ecosystems ).
To achieve sustainable development, renewable resources should not be used at a rate greater than their generation, while non-renewable resources should be used sparingly until they can be replaced by renewable resources. The generation of pollutants, on the other hand, has to address the possibilities of recycling and absorption by the environment.
