Ecology

In the past decades there have been drastic and irreplaceable disappearances in earth. These include the drying out of the Aral sea, the fourth largest inland sea in the world. The reason for its disappearance is that the water that poured into it has been diverted. Another extraordinary case is the death of millions of starfish due to radioactive military waste in the white sea. In the summer of 1988 12.000 dead seals washed to the shore in Texas.

These shocking and disturbing facts are the ones that begun to create awareness to the fact that humans are not being careful about the environment. The extent of such damage started with the industrial revolution. This is because industry means burning coal and oil in great amounts. This rises the levels of Carbon Monoxide in the air which has the ability to trap heat. So, eventually as CO2 rises so does the temperature of the Earth. In fact, global warming is expected to rise temperatures quicker in the polar regions than in the rest of the world. For example, the north polar cap in the last decade has thinned 2%. This is a significant increase that if it isn’t stopped might affect the whole Earth. This problem is one that affects globally.


Apart from the decrease in ozone, there is also a decrease in oxidation in the atmosphere. This means that the atmosphere’s ability to self-cleanse is being diminished. This is due to the great amounts of carbon monoxide being pumped into the air. There isn’t enough hydroxyl to clean it, let alone the methane gas. Some scientists believe that this problem is just as dangerous as the ozone depletion. Excess carbon dioxide is also to blame for global warming. Just as humans, the engines of civilization produce carbon monoxide. This means that the explosion of population plus the industrialization process has increased greatly the amount of CO2 pumped into the air. On top of that, the Earth’s two lungs, the forests and the oceans, are both being impaired. This contributes to the constant rising temperatures of the planet.

the destruction of the rain forests. The equivalent of the size of Tennessee is burned each year, usually to create fast pasture for fast-food beef. If we consider the fact that more different species of birds live in the rain forest than in all North America, we realize that in slashing the rain forests we are ensuring that they will be left without a home and therefore be doomed to extinction. As a result, species of animals and plants are vanishing one thousand times faster than at any point during the last 65 million years.

Yet another limiting factor is our normal spatial perspective. When analyzing the overall pattern of environmental damage we can find it difficult to establish sufficient distant perspective from which to make sense of the jumble of information. We can say that we are staring at a mosaic from too close. If we took a couple of steps back we might see a completely different picture. This means not only distance but also time. These changes seem decades away so we put them off for later.

Another common and mistaken belief is that the sky is limitless. We tend to think that it goes on forever and cannot be filled. The truth is completely opposite. The pictures brought back by astronauts show the atmosphere as a very thin translucent blanket covering the planet. “The distance from the ground to the top of the sky is no farther than an hours cross-country run”(page 83). This sounds incredibly small when we consider the amount of material that is pumped into the air daily.

In every breath we take, we fill our lungs with trillions of molecules of air. We are breathing the same air breathed by our ancestors. But i
