Consequentemente, diversos países europeus suspenderam a importação de produtos agrícolas espanhóis. O boicote causou um prejuízo de 200 milhões de euros por semana. A OMS anunciou que as E. coli encontradas nos pepinos não eram do tipo que provoca o surto. A Espanha ameaça processar o governo alemão pelos prejuízos a seus agricultores.(Adaptado revista veja, 8 de julho de 2011).Produtos agrícolas como o pepino, tomate, cenoura, cebola e batata são considerados “legumes”.

Por isso, são necessários alguns cuidados quando se compra esse tipo de alimento industrializado: devemos observar a data de fabricação, o prazo de vencimento do produto e o aspecto da lata, que não deve estar estufada. Se a tampa estiver estufada, é um sinal de que pode ter se desenvolvido no interior da lata, dentre outras bactérias, a causadora do botulismo, doença frequentemente fatal porque provoca paralisia respiratória.(Biologia, Ciência e Tecnologia. Sídio Machado, p. 132).Dona Maria observou que uma lata de sardinha estava estufada e resolveu não consumir o seu conteúdo.

Also present in our environment is radiation from the radioactive elements that occur naturally such as radium, thorium, and uranium.One of the most serious problems that can result from radiation given off by nuclear reactions is damage to the genes, the cells in living organisms that control hereditary factors. Exposure to radiation can cause a mutation, a change in some inherited characteristics of the organisms. Only a very small proportion of mutations are beneficial to the organism.The nuclear reactors that have been developed for experimental, peaceful and energy production purposes are surrounded by a heavy protective shield of concrete, or sometimes of lead, to protect the people who work with them.A further problem involves the disposal of radioactive wastes. As the number of nuclear reactors in existence has increased, so has the amount of dangerous waste products. They cannot simply be released into the environment because they could create a potential hazard for all living things in the world. Experimentation is trying constantly to find safe methods of getting rid of the harmful by-products of nuclear reactors. (p. 75)Adaptado de LIBERATO, Wilson Antônio.

In developing and transition countries there are well over one billion people with enough income to enjoy an affluent lifestyle.

Certain effects of their consumerism, such as pollutant emissions from cars, which cause urban smog and global warming, are a salient concern both locally and worldwide.

Now, 105 years later, Saudi women have also taken a step towards equality with the decision of King Abdullah to grant the women of Saudi Arabia the right to vote and stand for election.
