• Resumen

  • What follows is a commentary on the five chapters that Ramon Margalef wrote inthe first edition of this book in 1976 (which are reproduced here), with some remarks onevents that have occurred and new knowledge that has been acquired since then. Amongthe most significant events that have changed in the world is that the dominant Westernposition is today less clear than it was then. This, and the new technologies that favorthe control of information flows by large corporations or States and that openpossibilities of participation, may affect the way in which environmental issues will beaddressed in the future. The course that has been taken by the management of resourcesand of the environment is quite disappointing, with repeated failures of internationalefforts to change the dangerous trends that are still observed in climate warming, landuses or population involvement. We are still far from achieving many of the objectivesformulated more than half a century ago. In the energy field, not only has the transitionto clean energies not been achieved, but badly polluting techniques, such as fracking,seek to sustain a carbon-based economy. Many countries, such as our own, are highlyvulnerable due to the poor development of self-sufficiency. Despite advances, in natureconservation there are still threats associated with urban planning; loss of forests due tograzing, expanding cropland or fragmentation; oil exploitation in the Arctic; aforeseeable reduction of drinking water resources linked to climate warming and to theincrease of the demand and of pollution; sea acidification as a result of CO2 emissions,etc. Microplastics have become a global threat. We are still far from recycling asubstantial part of the materials we use. The need for new institutions and regulatorymechanisms subsists, becoming more urgent every day. But the coming to power invery important countries like the United States, Russia, Brazil or Indonesia of leaderssupported by interests associated with fuels, agro-industry, construction, etc. is a seriousobstacle. Many things have to change. Some countries have set off on the path todecarbonization, and China is moving, pushed by the catastrophic results of poorenvironmental management. The future is not closed.
