B/ the superstack is a giant chimney (2nd tallest in the world) on top of the Sudbury nucle smelting operation (largest nickel smelt in the world). The superstack has improved the ecological damage in Sudbury by placing the pollution so high in the air. Thus hasn't gotten rid of or reduced the pollution, just spread it over a wider area.
C/ Human activity has fine a lot if damage to Sudbury such as: deforestation,an inevitable near-total loss of native vegetation,exposed rocky outcrops, which have been permanently stained charcoal black, first by the pollution wafting over the decades from the roasting yards then by the acid rain that goes 3 inches into the once pink granite.
D/ NASA sent astronauts to train in Sudbury because of geology (not moonscape). approximately 1.87 billion years ago, a cataclysmic event occurred in the Sudbury area.
A gigantic meteorite travelling at around Mach 100, slammed into the Earth with the impact force equivalent to several billion tons of TNT.
D/ Human activity has never improved the environment.
E/ Other species use only resources necessary and sustainable within the area they live. Humans (because of capitalism) now use excessive resources to have unnedded luxuries, through extraction, and consumption. Before capitalism humans didn't do this.
Other species don't use fossil fuels, natural gases, minerals or gem stones. They harvest/ hunt just what is needed and what us supplied on the top of the earth.
Humans have destroyed 60% more plant and animal species and land then all other species and geological events of the earths history combined
Humans go about taking and changing the earth without ever worrying about what it will mean. Because of this we always see the damage when it's too late.
