Protection of the environment is now seen as a way of stabilizing the political economies of Third World nations. A failure to consider their stability leads to the alternative, chaos and the collapse of order. Liberia is an example, with anarchy in Monrovia, its capital. Farmers in Liberia used destructive agricultural practices, probably from the beginning of time. The nutrients in the soil have been depleted by overtilled, overfertilized, and overirrigated earth.
Excessive irrigation depletes the water level.
Additionally, the farmers used dangerous pesticides-ones already labeled as unsafe in the United States. As a result, farmers had to encroach further into the rainforest to find more arable land after a few years at one location. Soon, the rainforest, as a complete ecosystem, all but disappeared, and farmers had to abandon the soil. They moved to the cities, where there were no jobs, housing or food for all these new arrivals from the abandoned farms. The cities could not support the influx of these rural migrants.
