I'm a simple guy living in a complex world...so help me understand,

This is because the overarching purpose of Tesla Motors (and the reason I am funding the company) is to help expedite the move from a mine-and-burn hydrocarbon economy towards a solar electric economy, which I believe to be the primary, but not exclusive, sustainable solution.
"move from a mine-and-burn hydrocarbon economy".
But to manufacture the car's batteries, requires the mining of cobalt, nickel, manganese and lithium.
Processing of Lithium Ore
The lithium extraction process uses a lot of water—approximately 500,000 gallons per metric ton of lithium. To extract lithium, miners drill a hole in salt flats and pump salty, mineral-rich brine to the surface. After several months the water evaporates, leaving a mixture of manganese, potassium, borax and lithium salts which is then filtered and placed into another evaporation pool. After between 12 and 18 months of this process, the mixture is filtered sufficiently that lithium carbonate can be extracted.
South America’s Lithium Triangle, which covers parts of Argentina, Bolivia and Chile, holds more than half the world’s supply of the metal beneath its salt flats. But it is also one of the driest places on earth. In Chile’s Salar de Atacama, mining activities consumed 65 percent of the region’s water, which is having a large impact on local farmers to the point that some communities have to get water elsewhere.
As in Tibet, there is the potential for toxic chemicals to leak from the evaporation pools into the water supply including hydrochloric acid, which is used in the processing of lithium, and waste products that are filtered out of the brine. In Australia and North America, lithium is mined from rock using chemicals to extract it into a useful form. In Nevada, researchers found impacts on fish as far as 150 miles downstream from a lithium processing operation.
Lithium extraction harms the soil and causes air contamination. In Argentina’s Salar de Hombre Muerto, residents believe that lithium operations contaminated streams used by humans and livestock and for crop irrigation. In Chile, the landscape is marred by mountains of discarded salt and canals filled with contaminated water with an unnatural blue hue. According to Guillermo Gonzalez, a lithium battery expert from the University of Chile, “This isn’t a green solution – it’s not a solution at all.”
China is among the five top countries with the most lithium resources and it has been buying stakes in mining operations in Australia and South America where most of the world’s lithium reserves are found. China’s Tianqi Lithium owns 51 percent of the world’s largest lithium reserve in Australia, giving it a controlling interest. In 2018, the company became the second-largest shareholder in Sociedad Química y Minera—the largest lithium producer in Chile. Another Chinese company, Ganfeng Lithium, has a long-term agreement to underwrite all lithium raw materials produced by Australia’s Mount Marion mine—the world’s second-biggest, high-grade lithium reserve.
