Environmentalism is seen as the way environment affect human and other livivng organism. It means that the environment determine how organisms live in their various environment. The environment compose of the atmospher (air), the lithosphere (earth crust/sand/rocks) and the hydrophere (water/oceans/seas). All these environmental components affect how man live their life and his behaviour etc.
The reason for africans with aggressive habit and excess hardwork is due to the excess solar radiation (sun) they receive. The sun is very high in african regions expecially those in western eastern and central africa. We are known for aggressiveness and killing habit, less human feeling and butchering due to the fact that the sun affect us psychologically. In other hand, the western europe and northern america like canada some parts of america, receives little sunlight. The differences in the amount of solar radiation received is due to the angle each region make from the sun.The africans is at the center making an exact angle directly to the sun but as you go up to europe and norther russia, the sun fades and also as you go down to australia, south africa and antarctica the sun fades too. The region with low or little sunlight exhibit love and calm behaviour like europe and north america. Tha arabs experiences high drough due to high sunlight that evaporates the ground water and also they exhibit high lebel of death, killings and suffering.

Take mosquito for instance, mosquitos breed freely in warm areas like africa, they expresses their style of living because of the environment that they live, but take some few mosquitos to europe or northern america where the coldness of the environment is in excess, the will no even shake their head.

In conclusion, environment determins how organism behave. DETERMINISM coming soon.... Lalaiscla wtver.

All humans have the same mentality. There are good and bad people. The problem with Africa is that the bad ones get away with what ever they do. And when such happens it motivates others who can to do same. The places where you say they are good, go and see how easily they can kill fellow men if there is a breakdown in the rule of law. And yes, there are mosquitoes in Europe and some of Their flies even bite just like mosquitoes.
