Abstract

The world population has grown exponentially in the modern era, from about 2 billion in 1960 to over 7.6 billion today and the trend is still rising. An estimated 2050 world population will be 9 billion, and in 2100 over 11.2 billion [1]. The statistics showed that the world population increased by 1.7% annually in 1970-2000 and is projected to grow by about 0.8% year 2050 (1% between 2000- 2030 and 0.5% between 2030-2050). World population growth is not homogeneous, population growth is concentrated in countries from the developing world, and the biggest growth is in Asia and Africa. Everyone complains about the oil crisis, but this is not the most important because all bodies die turns biodegradation in oil and billions of animals die annually. The main issue for our planet is humanity and most species of animals multiply beyond measure, which increases demand for agricultural products, given that the planet’s natural resources remain the same. Meanwhile, statistics show increasing preference of people to eat meat, which implies the need to increase agricultural production too.
