A atriz americana Marcia Cross, uma das protagonistas da série de tv “Desperate Housewives” (“desperate housewives”), revela que tentou engravidar através de um doador de esperma e fertilização “in vitro”. Marcia Cross, de 45 anos, e seu marido Tom Mahoney, com quem se casou em junho de 2006, são pais de dvd Eden e Savannah, que terão um ano no próximo dia vinte de fevereiro. Cross pra revista de saúde “Health”. Ao contrair matrimônio com Mahoney “decidimos rejeitar a lua-de-mel e tentar a fertilização ‘in vitro'”. Quando soube que aguardava gêmeas “eu estava assustada”, ainda que, segundo relata a Cross por isso ele passou. No decorrer da grávida sofreu fortes tonturas e tinha desejos: “às duas da manhã me podia conceder de ingerir bifes”.
Figura dezenove shows a 30% increase in the forests of the United States that has taken place since 1950. Much of this increase is likely due to the increase in atmospheric CO2 that has already occurred. In addition, it has been reported that Amazonian rain forests are increasing their introduzida by about 34,000 moles (900 pounds) of carbon per acre per year (57), or about two tons of biomass per acre per year.
Figura 20 shows the effect of CO2 fertilization on sour orange trees. During the early years of growth, the bark, limbs, and fine roots of sour orange trees growing in an atmosphere with 700 ppm de CO2 exhibited rates of growth more than 170% greater than those at 400 ppm. As the trees matured, this slowed about to 100%. Meanwhile, orange production was 127% higher for the 700 ppm trees.
Figura 21: Grain yields from wheat grown under well watered and poorly watered conditions in open field experiments (61, 62). Average CO2-induced increases for the two years were 10% for wet and 23% for dry conditions. Trees respond to CO2 fertilization more strongly do than most other plants, but all plants respond to some extent.

Figura 21 shows the response of wheat grown under wet conditions and when the wheat was quando by lack of water. These were open-field experiments. Wheat was grown in the habitual way, but the atmospheric CO2 concentrations of circular sections of the fields were increased by means of arrays of computer-controlled equipment that released CO2 into the air to hold the levels as specified. Figura 22 summarizes 279 parelho experiments in which plants of various types were raised under CO2-enhanced conditions. Plants under stress from less-than-melhor conditions – common occurrence in nature – respond more to CO2 fertilization.
The selections of species shown in figure 22 were biased toward plants that respond less to CO2 fertilization than does the mixture actually covering the Earth, so figure vinte e dois underestimates the effects of global CO2 enhancement. Clearly, the green revolution in agriculture has already benefited from CO2 fertilization; and benefits in the future will be likely spectacular.
There are não experimental data to support the activation that increases in carbon dioxide and other greenhouse gases are causing or can be expected to cause catastrophic changes in global temperatures or weather. To the contrary, during the vinte years with the highest carbon dioxide levels, atmospheric temperatures have decreased. We also need not worry about environmental calamities, even if the current long-term natural warming trend continues. The Earth has been much aquecedor during the past 3,000 years without catastrophic effects.
Aquecedor weather extends growing seasons and generally improves the habitability of colder regions. Human use of coal, oil and natural gas has not measurably warmed the atmosphere, and the extrapolation of current trends shows that it will not significantly do so in the foreseeable future.
It does, however, release CO2, which accelerates the growth rates of plants and also permits plants to grow in drier regions. Animal life, which depends upon plants, also flourishes. As coal, oil and natural gas are used to feed and lift from poverty vast numbers of people across the globe, more CO2 will be released into the atmosphere. This will help to maintain and improve the health, longevity, prosperity and productivity of all people. Human activities are believed to be responsible for the rise in CO2 level of the atmosphere.
Mankind is moving the carbon in coal, oil and natural gas from below ground to the atmosphere and surface, where it is available for conversion into living things. We are living in an increasingly lush environment of plants and animals as a result of the CO2 increase. Our children will enjoy an Earth with far more plant and animal life as that with which are we now blessed. This is a wonderful and unexpected gift from the Industrial Revolution.
