New technologies provide utilities for knowledge acquisition and awareness, early evaluation of new knowledge, reaching agreements and communication of progress in the interest of the human welfare. This includes ethical aspects of protecting human life as well as aspects of consumer safety and the preservation of our natural environment.
The importance of stone tools, circa 2.5 million years ago, is considered fundamental in the human development in the hunting hypothesis. [citation needed]Primatologist, Richard Wrangham, theorizes that the control of fire by early humans and the associated development of cooking was the spark that radically changed human evolution.

As human technology becomes more evolved, such as that required to launch objects into orbit or to cause deforestation, the impact of human activities on the environment potentially increases. The anthroposphere is the youngest of all the Earth's spheres, yet has made an enormous impact on the Earth and its systems in a very short time.
The term is sometimes expanded to also include nanotechnology's health and environmental impact, but this article will only consider the social and political impact of nanotechnology. As nanotechnology is an emerging field and most of its applications are still speculative, there is much debate about what positive and negative effects that ...
Environmental technology (envirotech) is the use of engineering and technological approaches to understand and address issues that affect the environment with the aim of fostering environmental improvement. It involves the application of science and technology in the process of addressing environmental challenges through environmental ...
As indicated by the I=PAT equation, environmental impact (I) or degradation is caused by the combination of an already very large and increasing human population (P), continually increasing economic growth or per capita affluence (A), and the application of resource-depleting and polluting technology (T).
The environmental impact of nanotechnology is the possible effects that the use of nanotechnological materials and devices will have on the environment. [20] As nanotechnology is an emerging field, there is debate regarding to what extent industrial and commercial use of nanomaterials will affect organisms and ecosystems.
