How Does Human Activities Cause Global Warming?

Using non biodegradeable items, such as plastics, auto fumes, carbon monoxide emissions, using too much electricity, you name it, we're doing it all wrong.  Give back what you take from this earth.  Mass consumption of everything is going into our environment.  What is the good of wearing gold when they mine it, they use arsenic and mercury and other dangerous chemicals to extract the gold, which then ends up in landfills, and lakes,  leaking into our water drinking supply.  Improper disposal of computers, fridges, microwaves, air conditioners seeping freon into the atmosphere and once again polluting our environment.. There are too many things to name.  Recycle, reuse, reduce our only hope to slow down the damage that is already done and still being done
