Question: What are the major environmental dangers facing us today?
Answer: Though some progress has been made in the rich nations in controlling pollution and protecting ecosystems, the situation in the rest of the world is dire. Since the rich countries account for only some 20% of the worlds’ landmass, it can safely be said that the global environment is at risk. A list:

- Natural ecosystems are disappearing rapidly. If things continue as today, in twenty to thirty years most of the remaining tropical forests, a large part of mountain forests and most of the world’s wetlands will be gone or severely marred by pollution.

- Air and water pollution are costing millions of lives each year – through acute infections or chronic health problems that lead to premature death. Soil pollution threatens ground water supplies and as such, can develop into a major cause of water pollution and health hazard.

- Global warming will raise sea levels by several feet in this century, threatening the half of the global population that lives in coastal areas: at sea level, and sometimes below it. Moreover, it leads to increasingly strong and therefore destructive storms and flooding, and upsets ecosystems through the expansion of non-indigenous plant and animal species. In drier areas it also leads to desertification.

- Desertification and soil erosion, caused by wind and water, and salinization of irrigated areas due to poor water management lead to a steady decrease in the quantity and quality of agricultural land. This is true especially in the most densely populated areas of the world.

- By 2050 over half the global population, in rich as well as poor countries, is expected to face serious fresh water shortages.
