Uno de los objetivos de la FAO (Organización de las Naciones Unidas para la Agricultura y la Alimentación)
es reducir el número de personas hambrientas en todo el planeta. Parte de su estrategia está sustentada en la
inversión en biotecnología y desarrollo de alimentos “genéticamente modificados”. A pesar de su intención,
esta propuesta ha sido controvertida por un grupo significativo de dirigentes e investigadores, tanto en Europa
como en América Latina, ya que
A. Los logros en cuanto a manipulación genética de alimentos, a escala mundial, son mínimos
B. Consideran poco rentable la comercialización de estos alimentos, pues su alta productividad
disminuye su valor
C. Están preocupados de que la nueva tecnología pueda traer riesgos tanto ambientales como de salud
D. Modifica el orden natural de las especies vegetales y animales generando un desequilibrio ambiental

Our planet has experienced five major extinctions in the four billion year history of life. the first, 450 million years ago, occurred shortly after the evolution of the first land-based plants and 100 million years after the cambrian explosion. the second extinction occurred 350 million years ago, causing the formation of coal forests. next earth experienced two mass extinctions during the triassic period, between 250 and 200 million years ago. the fifth mass extinction occurred 65 million years ago, ending the reptilian dominance of the earth. according to richard leakey, the sixth mass extinction is happening right now. leakey suggests that we, the human race, are the cause. each year, at our hand, approximately 50,000 species vanish from earth. he believes that man is destroying earth at a rate comparable with the impact of a giant asteroid. leakey's statistics indicate that 50% of earth's species will become extinct within the next 100 years assuming leakey's hypothesis of a sixth mass extinction to be true, how will we expect the model to change? a) a sharp spike in the graph approximately 100 million years from now b) a dip in the graph, followed by a sharp spike about 100 million years from now c) a sharp spike in the graph immediately following the "0" location of the x axis d) a plateau following the "0" mark on the x axis, followed by a gradual rise to a new peak
