Attempting to understand the universe, build a conceptual framework, research and evaluate it merits, we must consider what science has brought to the humanity. and the big three benefits are:
"Genetic engineering," the creation of artificial life forms, is nothing new. It has been going on for thousands of years. Essentially all the food we eat is derived from deliberate human manipulation of plant and animal gene pools. Until the mid 20th century, the techniques employed were cross-fertilization, selective breeding, population culling, and other "natural" methods. As our understanding of genetics matured, it became possible to directly manipulate cellular material (ca. 1970+). Molecular biology now offers an ultimate genetic control technology.
CONTROL OF INFECTIOUS DISEASE
The control of the microorganisms (bacteria, viruses, parasites) that cause infectious disease is perhaps the single most important contribution of science & technology. In fact, few of us in this room would be alive today without it (because a direct ancestor would have died too early). But as recently as 350 years ago, communicable disease was thought to be produced by evil spirits, unwholesome vapors, or other mysterious agents. No one imagined that it was caused by invisible lifeforms until Leeuwenhoek in 1676 first used the microscope to study biological systems. "Public health" consists mainly of systematic methods for controlling microorganisms.
ENERGY SUPPLY FOR ALL THE NEEDS
Only since 100 years ago, the mankind has been moving on with the energy source called petrol or oil. It brought big and great benefits but also negative points. As many scientist say the oil era is almost over and we must think in another sources.
Soon the power will come from the water...
