Biodiversity hotspots were first identified as areas rich in endemic plants and containing a high diversity of species. Their ecosystem was suffering the threats of outsiders and with time, lost most of their original habitat. Today, we are more specific with the identification of hotspots as we apply two specific criteria in their definition. First,… Continue reading What Is a Biodiversity Hotspot or Ecological Hotspot?

What Are the Benefits of Biodiversity and What Is Genetic Erosion?
We know of more than 1.7 million species, but since most haven’t been discovered yet, we can realistically estimate that the actual number is closer to 40 million. Insects alone count for approximately 75% of all species. It is a fact that from a certain length, the number of species is negatively correlated with their… Continue reading What Are the Benefits of Biodiversity and What Is Genetic Erosion?
The Fragility of the Food Chain
Every living organism on this planet is part of a food chain. What is a food chain? A food chain is the process in which different species exchange energy from one to another by eating each other. Consequently, all species are interconnected somewhere in the food chain. From plankton and vegetation to lions and humans,… Continue reading The Fragility of the Food Chain
What Are the Problems with Overpopulation? Are Condoms and Contraceptive Pills the Only Solution?
The human population started booming in the 19th century with the improvement of common hygiene and medicine techniques. In the 20th century, the rate of population growth was exponential, meaning that it was frequently doubling. With the increasing consumption of resources and expansion into new territories, a bigger population inevitably means a bigger impact on… Continue reading What Are the Problems with Overpopulation? Are Condoms and Contraceptive Pills the Only Solution?
From Industrial Revolution to Industrial Evolution
The era of industrial revolution is noted by population growth and the emergence of industries. These two factors brought higher consumption and higher production. Consequently, human activity is capable to massively exploit the world’s resources. Industries has as much impact on the planet as a city population has on their municipality or a family on… Continue reading From Industrial Revolution to Industrial Evolution
The Sixth Massive Phase of Extinction
Life on earth combines an amazing 40 millions different species. Insects, animals and vegetation normally spread in areas where their morphology can deal with the climate and where they can better feed themselves. This is known as the ecological niche and it can be destabilized.
The Probability of Intelligent Life in the Universe
The goal of this section is not to debate whether or not we are the only intelligent life in the Universe, but rather to help better understand that the chances of intelligent life existing elsewhere are as low as winning the lottery 5 times in a row. Here is why.
