Respuesta:We know the damage we have already done to the Earth in the name of progress: We have polluted its atmosphere, destroyed its forests, poisoned its rivers and caused the extinction of species that we did not even know existed. We are aware that we must change our attitudes about the consumption and pollution of natural resources by industrialized societies. We know that, despite scientific advances in agriculture, it is becoming increasingly difficult to feed the world's growing population. Yet all the indicators show that these destructive trends, which have accelerated so dramatically over the past 40 years, will continue well into the next century. For example: -Every day between 50 and 100 species of animals and plants become extinct, as their habitat is destroyed. -Tropical forests are being excavated so fast that half may disappear in the next 40 years. -Uncontrolled fishing has reduced the stocks of almost all commercial species, some to less than a tenth of their previous number. The number of motor vehicles around the world is expected to increase steadily with corresponding increases in CO 2 emissions that accelerate climate change caused by the greenhouse effect. We must do something to stop this disaster that threatens not only our generation but generations to come. The time has come to tighten the screws on politicians, to accelerate the pace of change. The evidence of what happens on Earth demands no less of us.
