6 Problems Caused by Shrinking Biodiversity

  • 2 of 6


2. Reduced Food Security

Reductions in biodiversity, however, do not only occur during deforestation or through poaching. The introduction of new species, too, increases competition amongst locals and often leads to extinction of native populations. In much of the world, this is happening on farms, too, where foreign breeds of cattle are being imported, pushing out natives.

This means that the world’s livestock population is becoming increasingly narrow; and more vulnerable to disease, drought, and changes in climate.

Read with a sickened heart and stomach. This is exactly why the Rethugicons CAN NOT win.

The causative disease is simply human over-population and no amount of application of well intentioned "Green wash" will magically make it all go away. Humans require masses of space to build houses and cities and require enormous chunks of land to feed the rapidly multiplying masses. All this land is taken away from natural fauna and flora and the tiny bits we leave nature is polluted on land, sea and air by masses of our solid, liquid and gaseous waste. Even in this article that once again deals with the symptoms of the overpopulation disease, poor old David DeFranza cannot bring himself to once mention the underlying disease. To effectively deal with a problem honesty and courage are essential requirements – both these qualities are sadly absent from most of the popular “Green” movement.

Support organisations like the World Land Trust and the UK Woodland Trust. And battle invasive weeds!

humans are ok. it's consumers that are sucking the life from our planet while polluting her. not all humans are consumers. there's a major difference.

Well, I guess I was wrong, bacteria are actually smarter than humans.....

symbiosis (smb-ss)
The close association between two or more organisms of different species, often but not necessarily benefiting each member. The association of algae and fungi in lichens and of bacteria living in the intestines or on the skin of animals are forms of symbiosis. Some scientists believe that many multicellular organisms evolved from symbiotic relationships between unicellular ones and that the DNA-containing organelles within certain eukaryotic cells (such as mitochondria and chloroplasts) are the product of symbiotic relationships in which the participants became interdependent. There are four forms of symbiosis: amensalism, commensalism, mutualism, and parasitism
