Extinctions and Us.
When we hear of extinction, most of us think of the plight of the rhino, tiger, panda or blue whale. But these just a few sad sagas of the large extinction puzzle. If you take into account the overall numbers, of the 40,168 species that the 10,000 scientists in the World Conservation Union have assessed: 1 in 4 mammals, 1 in 8 birds, 1 in 3 amphibians, 1 in 3 conifers are at risk of extinction. Moreover, about 40 per cent of the examined species of planet earth are in danger, including perhaps 51 per cent of reptiles, 52 per cent of insects, and 73 per cent of flowering plants.
The reason behind bombarding you with all these statistics is to point out that our entire ecosystem is at risk. The Food Web or the Food Chain is layers of species interlinked with each other. These species are both herbivores and carnivores. One species consumes another to survive. So it is like grass eaten by a deer, and a deer eaten by a tiger.
Now because the ecosystem is too big every animal has a primary source of food and an alternative source of food. And that is precisely how the entire Food Chain or the ecosystem functions. So if one species goes extinct, the animal that was dependent on it becomes dependent on the alternative food source. So the alternative source becomes primary for that animal and it gets consumed at a faster rate. And because this continues, we have more and more such species getting consumed and going extinct.
But how do we consider humans responsible for this? That’s because humans are responsible for deforestation, and hence for the diminishing habitats for animals. Humans are responsible for over-fishing, so less food for larges fishes. To add to these woes, we have pollution and global warming that is making condition for these animals even worse. In effect we are disturbing the entire ecology and the Food Chain. This goes unnoticed because human life is yet not hit by this imbalance directly.
We should put a stop to this, and the most important step for that is afforestation. Re-establishing habitats for animals increases the chances of revival of the endangered ones. We should also stop using products made out of animal skin or bones. After all, our luxuries are less important than tackling this ecological imbalance. And we should make sure that it gets restored.
