The Problems of Earth resume: Loss of biodiversity

Loss of biodiversity is a decrease in the diversity of life forms within a species, an ecosystem, or the Earth as a whole.   Brazilian Amazon rainforest (International Business Times, 2018) The loss of biodiversity can lead to a breakdown in the functioning of the ecosystem where decline has happened. An area’s biodiversity may increase and decrease following natural cycles. In contrast, human-driven biodiversity loss tend to be more severe and longer-lasting: ecosystems have adapted to the challenges of natural disturbances. However, humans, our crops, and our food livestock take up half of the world’s habitable land, and overexploits 90% of the fishing stocks. This massive conversion of forests, wetlands, grasslands, other terrestrial ecosystems, and the ocean, has produced a 60% decline in the number of vertebrates worldwide since 1970.  The Rockefeller Foundation/Lancet Commission reports that human health depends on natural systems functioning properly.

The Problems of Earth: Environmental impacts of war

Environmental impacts of war are the damage that warfares cause on the environment.   Destroyed building after a bombing in Syria (Southfront, 2016) War has a destroying impact on the environment. Air, water and soil are polluted, human beings and animals are killed, and numerous health issues occur among those still living. Back in history we find that the armies of ancient Rome, to ensure the total capitulation of their enemies, sowed salt into the cropland of their foes, making the soil useless for farming. This practice had a devastating environmental effect.   Modern chemical, biological, and nuclear warfare has the potential to wreak unprecedented environmental havoc. Fortunately, we have not seen it yet –perhaps the Japanese community will disagree on that*.  Comparison between the nuclear bombs dropped in Japan, and modern ones. (Nairobi Wire, 2017) During the war, extensive damage is done and many people suffer health effects from weapons applied to de...
