This idea was opposed to the Malthusian theories, and later the neo-Malthusian, it argued that population growth would tend to balance "natural" that happened along the stages of demographic transition. But also received criticism because it puts the story as responsible for solving the problem of high growth, it would be "natural" three phases, reaching a balanced population. Do you believe that all people pass through three phases demographic presented by this theory? Justify your answer. The Second acceleration of population growth occurred in 1950, after the Second World War, particularly in underdeveloped or poor countries. This period was marked by the emergence of new independent countries of Africa and Asia and great achievements in health care, such as the production of antibiotics and vaccines against a number of diseases. These achievements have spread by developing countries thanks to the work of international aid organizations and cooperation, as the World Health Organization (WHO) and the International Red Cross. Moreover, the process of expansion of multinational big pharma settled in underdeveloped countries were industrializing. Some remedies have become gradually more accessible and affordable.

Even after decades and thousands of vaccination campaigns, more than 30% of children around the world do not have access to the most important vaccines: diphtheria, tuberculosis, tetanus and polio. In the early 1990s, Charles Arntzen, Texas A & M University, devised a way to solve these problems in a very cheap and effective: preparing genetically modified foods, able to produce vaccines. Bananas, potatoes or tomatoes, to be consumed, the body would be stemmed with the necessary inoculations. The test results seem clear that edible vaccines are indeed effective. However, several questions remain to be answered, and several issues need to be resolved before the mass release of these vaccinations. Among the obstacles is that the potato should be eaten raw. This will be the vaccine of the future? It has much more to know about this. How about doing a search?

Ova ideja je za razliku od Maltuzijanski teorijama, a kasnije neo-maltuzijanskog, tvrdila je da je rast populacije će teže izbalansirati "prirodno" da se dogodilo uz fazama demografske tranzicije. No, također je dobio kritike jer stavlja priču kao odgovorni za rješavanje problema visoke rasta, to će biti "prirodni" tri faze, postizanje uravnoteženog populaciju. Vjerujete li da su svi ljudi prolaze kroz tri faze demografske predstavio toj teoriji? Opravdati svoj odgovor. Drugo ubrzanje rasta stanovništva dogodila se 1950, nakon Drugog svjetskog rata, osobito u nerazvijenim i siromašnim zemljama. Ovo razdoblje obilježeno je pojavom novih neovisnih zemalja Afrike i Azije i velike uspjehe u zdravstvu, kao što su proizvodnju antibiotika i cjepiva protiv brojnih bolesti. Ovi uspjesi su se proširile prema zemljama u razvoju zahvaljujući radu međunarodnih humanitarnih organizacija i suradnje, kao i Svjetska zdravstvena organizacija (WHO) i Međunarodnog crvenog križa. Osim toga, proces proširenja multinacionalne Big Pharma naselili u nerazvijenim zemljama su industrijalizacije. Neki lijekovi su postali postupno pristupačniji i pristupačne. Pročitajte više na tablici: Imaš cjepivo danas? Tablica 2 Jeste li pojeli svoje cjepivo danas? Čak i nakon desetljeća i tisuće kampanja cijepljenja, više od 30% djece diljem svijeta nemaju pristup najvažnijih cjepiva: difterija, tuberkuloza, tetanusa i dječje paralize. U ranim 1990-ih, Charles Arntzen, Texas A & M University, smislio način kako riješiti te probleme u vrlo jeftin i učinkovit: pripremu genetski modificirane hrane, u stanju proizvoditi cjepiva. Banane, krumpir ili rajčica, da se konzumira, tijelo će biti zaustavljen s potrebnim cijepljenja. Rezultati ispitivanja čini jasno da jestiva cjepiva su zaista učinkoviti. Međutim, nekoliko pitanja ostaje da se odgovori, a nekoliko pitanja treba rješavati pred masovnim izdavanjem tih cijepljenja. Među preprekama je da krumpir treba jesti sirovo. To će cjepivo prema budućnosti? To je puno više znati o tome. Kako o radiš za pretraživanje?
