Bird Flu

"At this moment, there is no pandemic influenza in the United States or the world. But if history is our guide, there is reason to be concerned. In the last century, our country and the world have been hit by three influenza pandemics - and viruses from birds contributed to all of them."
- George W. Bush

Rainforest Facts

We are losing Earth's greatest biological treasures just as we are beginning to appreciate their true value. Rainforests once covered 14% of the earth's land surface; now they cover a mere 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years.

Rainforests are being destroyed because the value of rainforest land is perceived as only the value of its timber by short-sighted governments, multi-national logging companies, and land owners.

Nearly half of the world's species of plants, animals and microorganisms will be destroyed or severely threatened over the next quarter century due to rainforest deforestation.

Global warming

Global warming is an increase in the average temperature of the Earth's atmosphere and oceans. The term is also used for the more specific scientific theory of anthropogenic global warming, which states that much of the recent observed (and projected) global warming is human-induced and the result of a strengthened greenhouse effect caused by man-made increases in carbon dioxide (through the burning of fossil fuels and deforestation) and other greenhouse gases. The natural greenhouse effect keeps the Earth 30 °C warmer than it otherwise would be; adding carbon dioxide to an atmosphere, with no other changes, will make a planet's surface warmer. Current research tries to uncover more details, e.g. about positive and negative feedback mechanisms, to allow a more precise quantification of the effects of global warming.

the ecological effects of war

The US is now committed unilaterally to an invasion of Iraq. Up to 250,000 soldiers are being mobilized, along with an armada of warships, and thousands of aircraft and missiles. As shown by the war in Kosovo and in the earlier US-led war against Iraq, human death and the obliteration of "military targets" will not be the only results of the coming war. The longer-term consequences will include an ecological disaster that will visit itself on future generations. Iraq has still not recovered from the effects of the last war. In particular, the presence of large amounts of depleted uranium (DU) from anti-tank cannons and landmines continues to cause large numbers of stillbirths, children born with defects, childhood leukemia and other cancers. The Balkans still suffers the aftermath of the bombing of petrochemical plants, which released clouds of toxins into the air and rivers.

Population and the Environment: The Global Challenge, Population Reports, Series M, Number 15

As the century begins, natural resources are under increasing pressure, threatening public health and development. Water shortages, soil exhaustion, loss of forests, air and water pollution, and degradation of coastlines afflict many areas. As the world's population grows, improving living standards without destroying the environment is a global challenge.

Most developed economies currently consume resources much faster than they can regenerate. Most developing countries with rapid population growth face the urgent need to improve living standards. As we humans exploit nature to meet present needs, are we destroying resources needed for the future?

An Ecological Source of Information

Every minute enough of the Sun's energy reaches the Earth's surface to meet the world's energy demands for a whole year. Combine this powerful energy source (the very source of life for our planet) with other readily available energy sources like wind, moving water and heat from within the Earth (geothermal heat), it almost seems incredulous that our human population depends on the burning of fossil fuels to meet nearly all of its energy demands. And this picture doesn't look like it will change very much in the near future.

Why fossil fuels? The fossil fuels we largely depend on today are coal, oil and natural gas. They are called non-renewable energy sources. But if you think about it, that description is actually another way of saying we use them faster than they form. Over 100,000 times faster to be exact! So how did we ever decide this would be the primary energy resource to power human development and progress?

Human Population - Global Issues

"Go Forth And Multiply!" That's what the human population has successfully been doing for thousands and thousands of years, expanding, exploring, migrating, conquering, utilizing, evolving, civilizing, industrializing, and now, destroying the very land upon which we live.

Many feel (as has been the case throughout history) that the major international wars to be fought in the future will continue to be over natural resources. Power conflicts and self-interest will perhaps mean that there will be gross violation of basic rights and death or misery for millions of innocent people. Throughout history, most wars have had trade and resources at their core (leading to ideological battles) fueled by imperialistic motives. In the future, while this pattern is likely to continue, as resources get depleted and wasted in these wars (hot and cold), additional conflicts and contention will arise through access to even more limited resources.
