Man as a living being


1. Man’s nature is different from all other life forms, including animals. This distinction is of great importance for two reasons. First, without this distinction, government can treat humans as though animals. Second, because man does not see, or understand the difference, he can see no escape from the tyranny he suffers.
That is why the ongoing debate about the ethic of cloning is a controversial one.
2. Twins are clones – two organisms that share the same genetic material – but not all clones are twins. If the cloned organisms are born at the same time, then they’re twins.There is no known technology that can create an instant copy of a living organism. Experiments are intergenerational (относящийся к разным поколениям), meaning the clone will be younger than the original.

3. Despite (вопреки) several high-profile claims (заявление) in the past, there is no scientific evidence that anyone has successfully delivered an artificially cloned human being. Researchers can apply for a licence to clone human embryos for stem cell research. It is illegal, however, for any of those embryos to be implanted into a surrogate mother. Human-animal hybrids – In 2008, the Human Fertilisation and Embryology Authority approved research into ‘cytoplasmic’ hybrids, the transfer of human genetic material into a cow egg cell.
4. The man is fundamentally different from all other life forms by genus, yet within that family, is a precious and unique individual, is of fundamental importance to understanding ethics, morality, human rights, politics, the law and justice. It begs we fully understand that each individual’s relationship to others, in societal terms, not only must begin with study of the individual, it must also conclude with that satisfaction, because without individuals there is no societal aggregation.

Should we eat bugs?


Do you know what Entomophagyis?
Entomophagy is the practice of eating insects - including arachnids (tarantulas) and myriapods (centipedes).



The word “entomophagy” derives from the Greek term éntomos, or éntomon, meaning, “insect(ed),” literally meaning “cut in two,” referring to an insect’s segmented body, and phăgein, “to eat.” Combined, the two terms mean, “insect eating.”
As a point of information the word itself is a rather new term. There’s no record of its coinage in the Oxford English Dictionary and its first usage to denote a human behavior may well be as recent as the 1950s.
There are no words equivalent to ‘entomophagy’ in the languages of the many ethnic groups that practice insect consumption, simply because these peoples never distinguished between insects and other varieties of food.

Why eat bugs?


Insects have served as a nutritional, tasty and safe food source for people for tens of thousands of years, all over the planet. Today insect eating is rare in the developed world, but eating insects is a common practice in over 13 countries. Insects remain a popular food in many developing regions of Central and South America, Africa, Australia and Asia. It’s only a matter of time till Eurocentric based cultures, like the United States, Canada and Europe catch on. Read more here.

Do you know what is/was the largest plant and animal

What do you thunk about this picture?



Do you know that sauropods were clearly the largest land animals that ever existed, but it has been difficult to estimate the length and mass of particular species because this has to be based on reconstructions of skeletons and soft tissue estimates.



There are some pictures of other large living beings below:


Sequoia


Blue Whale
