Unexpected Demographic Growth Might Put in Danger Earth's Resources

In only five decades, it seems that Earth has experienced its most amazing expansion of population, 3 billion to 7 billion individuals. While thinking about the pressure, this fact puts on the shoulders of Mother Nature, one question needs to find its real answer: is there enough to keep everyone going?

United Nations and the U.S. Census Bureau estimated that the entire population will reach approximately 10 billion by the end of this century. Afterward, scientist forecast a regression, generated by the development of poor nations.

If this prevision isn't accurate, individuals have to compete against each other for food and water resources. Such a competition will most likely put the fragile balance of ecosystems, and wildlife in general, in danger .

Biologist Edward O. Wilson is the author of the bottleneck theory. In his vision, the population growth will generate a lot of pressure for our planet's resources, then the situation will light up as the number of individuals will slowly decrease.

The U.N. Studies focused on birth rates showed the fact that the demographic expansion will stop until 2050, in Sub-Saharan Africa. From six children per woman in 1990, the deadline indicates a rate of three children per woman.

Even so, 2 billion people will have to share the resources in that particular area.

Scientists are aware of the fact that developed countries provide lower birth rates than the poor ones.

While analyzing India's situation, researchers found out that, despite its economical growth, three quarters of its population have a lifestyle supported with just $ 2 a day.

As a paradox, its poorest areas provide the most newly-born. For instance, Bihar, Madhya Pradesh, Rajasthan, Uttar Pradeshm manage to come up with an outstanding birth rate of 3.9.

All in all, lower birth rates are expected in the future, and this aspect is connected with the development of nations which at this point in time, are one of the poorest countries in the entire world.

This correlation isn't certain, despite all the numbers and studies showcased by researchers all over the world.

As no authorized voice is able to state for a fact that global population will decrease, deforestation processes, the amount of water, food and fuel we use should be better managed.
