In a perfect world, our progress and development would be shaped by whatever our needs are in that moment with taking into account that our choices now may affect future generations negatively, from here comes the definition of sustainability.
Sustainability is the study of how natural systems function, it's nature's ability to endure diversity in biological systems and to be able to maintain it without losing its balance, where everything has an origin and goes somewhere, a perfect ecosystem in which there are no nonbiodegradable substances that are remaining from human activity, buried in the ground or flowing with the ocean.

But with humans trying to sustain their way of modern life, they consume more than they should and produce waste that cannot be naturally decomposed. There are countless examples throughout human history where civilization has damaged its environment and seriously affected its survival chance.

We now live in a consumerist world, where we consume a large number of natural resources, power, and food significantly larger than less developed countries, it's here where sustainability comes to define the fine line between the need to move forward technologically and economically and the need to protect the environment that we live in, sustainability is the answer to how we can live in harmony with the natural world around without doing any harm to it and how to reverse the damage that has been done, it's also about examining the long term effects of the actions that humans take, taking into account how it will affect future generations and asking questions about how it may be improved.

There are some core areas that define the science of sustainable development. The first area is economic development: This is the issue that proves to be the most problematic as most people disagree on political ideology as in what is and is not economically sound, and how it will affect businesses and by extension, jobs, and employability, it also would be quite challenging to get businesses and organizations to follow sustainability guidelines beyond their normal legislative requirement, also to encourage individuals to do their part one person can rarely achieve much, but taken as a group, effects in some areas are cumulative, economic development is about finding a balance between our way of life and protecting the planet that we live on.

The second area is environmental protection: It's pretty much common sense what is needed to be done to protect the environment whether that is recycling, reducing our general consumption, walking small distances instead of taking the bus or driving, environmental protection is the biggest thing we are concerned about, knowing how it can affect the future of humanity, it also shows the guidelines that we can follow to help us to a more sustainable future like how we should study and protect ecosystems, improve the air quality, and switch to more sustainable resources, it is recognized that developing technology and biotechnology is the key to this sustainability, and protecting the environment in the future
from the potential damage that technological advancement could potentially bring.

At last, the most important thing is that we continue to educate ourselves on the matter, spread awareness amongst those who lack it, try and make the world a better place right now without destroying the possibilities for the next generations, figure out how to reach a point where our social progress and our economic development don interfere with the wellbeing of our environment, and finally, take into account how the world will turn out in 100 years if we keep our wasteful habits.
