Human survival

Might we assume then that the search for relevance is a search for ways to be reoriented toward the higher or highest evolutionary priorities Even discarding the (controversial) need for growth in humanity s kinetic machinery, there is a clear need for effort to just sustain the feeder reactions and to control the undesirable end products from the total system. The catalytic scientist surely feels that he must already be—and is—a key participant in that very play (or drama) of human survival or evolution. 

During the last three decades an increasing awareness is observed into the environmental problems caused by human activities22. These environmental problems are a direct risk for human health and the human survival potential. To challenge these problems, human activities, in particular agricultural and industrial production processes, industrial products, and transport, but also the individual way of living have to be made more sustainable. Sustainability does not only focus on the environment. It also involves economic aspects and aspects dealing with implementation. Implementation includes in this respect education, acceptance, human involvement into the application, and incorporation into the human mind. 

Every time an item is placed in the refrigerator we depend on lower temperatures to slow reaction rates to prevent food spoilage. The effect of temperature on reaction rates is also illustrated by its impact on human survival. Normal body temperature is 37°C. An increase of body temperature of just a few degrees to produce a fever condition increases the metabolic rate, while lowering the body temperature slows down metabolic processes. The slowing of human... 

Helium is nontoxic and will not poison or affect living tissue. That is why it is safe to inhale helium and pretend you re a comedian.1 The only danger that helium can present is that it can fill up a room, displacing oxygen so that there is an insufficient amount for human survival. However, because helium floats up and out of any room, this situation is extremely unlikely. 

One other essential material for human survival is drinking water. Global population is increasing while fresh water supplies are decreasing. The United Nations predicts that by the year 2025,48 countries will be short of fresh water, accounting for 32% of the world s population [31-33]. Ecological recovery via MNT will make raw water for the water supply cleaner and more abundant ... 

There are tens of millions of known chemical compounds and more being assembled every day. The number of future combinations of elements is virtually infinite, and the periodic table continues to expand. We ve become almost too good at our craft. Like kids in a candy store, the question is not whether there is more chemistry to be discovered but where we should focus first. With all the problems facing human survival, we can t afford to sit like a million monkeys working in a million labs and hope that solutions will arise. Take, for example, the problem of drug discovery. How do we decide, out of the tens of millions of compounds out there, which medicines to test as cures for diseases In the past, there have been some fortunate accidents, but we can t rely on luck. 

Communication between cells is essential for human survival and is provided by the nervous and endocrine systems. 

The study of matter is fundamental to human survival, and it is linked forever to civilization. On a practical level, humans have come to dominate nature because we can identify, manipulate, and transform the materials of the world. We take a stone and make an axe, then use the axe to chop down trees, transforming them into firewood and lumber to make houses. Given the importance of the material world, it is not surprising that humans have spent a great deal of time trying to determine what matter is and how it works.

In the last phase of the Stone Age, about 8,000-9,000 years before our age, marked by the domestication of animals, development of agriculture, and the manufacture of pottery and textile, the human population on earth approached the one million level. Thereafter, however, the population increase necessarily went from strength to strength. By the beginning of the Common Era it had reached the 300 million level, grew to 1.6 billion by 1900, and is at present around 6.5 billion. There is a compelling reason to curb this rate of population increase, as it already endangers human survival. 

Air, water, and food are the minunum essentials for immediate human survival. Air and water are generally available in most places on earth. The quest for food often dominates human behavior and directly affects many aspects of human society, including group size and social organization, residence patterns, technology, and transportation. Many fundamental questions in archeology revolve around the nature of human diet and sources of food. 

A complete protein is one that provides all essential amino acids (Section 23.5) in appropriate amounts for human survival. These amino acids cannot be synthesized by humans, but they are needed for the biosynthesis of proteins. Lysine and methionine are two essential amino acids that are frequendy in short supply in plant proteins. 

Dopamine is the neurotransmitter that is most implicated in addictive behaviors. Drug addictions occur more readily in people who have inherited an abnormal dopamine receptor, for example. It is also a major transmitter in the reward pathway of the brain. Pleasurable activities such as eating and sex, release dopamine, so in terms of evolution, behaviors that promote human survival activate our built-in reward system. 

FIGURE 6.23.6 Most of the improvements in medicine have benefited the young, leading to speculation that human life span has a natural limit. This figure shows how human survival rate has changed over the years. (Redrawn from Kent, D.M., Am. ScL, 96, 358, 2008.)... 

Civilian submarines are also an area of growing interest. Although scientific submarines have mapped significant portions of the oceans, the majority of the ocean floor remains unexplored. As natural resources on the land become scarcer, humanity will rely more and more on the ocean to fill the need for materials, and the exploration of the ocean will take on even more significance. Civilian submarines also fill the need to educate the public about environmental protection. By providing a view of the ocean and demonstrating its importance to human survival, civilian submarines promote the cause of... 

When society transitioned from hunting to farming, domesticated animals provided milk for adults (and dairy products, with a little bacterial help). This new source of calories increased ERD and helped humans survive. Any adult with a lactase gene that was accidentally left on could take in more calories and would pass along their turned-on gene to their children. 

The great explorer Captain James Cook was another victim of TTX. In September 1774, he and two of his crew ate some puffer fish and fed the remains to the pigs on board ship. The humans survived the extraordinary weakness and numbness but the pigs did not, probably because the pigs had eaten the more toxic parts of the fish.
