You can't rectify your past mistakes and move on to a brighter future if the end result of them is still in existence. We as humans have made many mistakes and the remains of our forefathers are a constant reminder of the abuse and negligence of our past ways. As we move on and rebalance the world we must accept that a big part of creation is destruction.
Luckily the TECHN0CULT has D3M0LISHERS for that exact reason. They roam the earth and tear down the remnants of our missteps and leave the rubble behind for mother nature to take over.
The fruits of our labour will never blossom if we are unwilling to deal with the weeds and work around the problems.
