What are three different reasons oil sands are positive?

Here's your answer!!

1)The responsible development of oil sands is a key driver of Alberta's and Canada's economy. It creates jobs and tax revenue for the government which supports the social programs and capital infrastructure projects we rely on.

2)Crude oil derived from the oil sands is refined into products, such as gasoline, diesel, and aviation fuel, which keep us warm, power our industries, and help us move about the country and the world (not to mention cooking those turkeys). With conventional oil supply declining, the need for oil sands is increasing.

3)A strong oil sands sector drives a strong national economy by attracting capital, creating jobs, and supporting public services. ... Local companies in every province supply goods and services to the oil sands—creating jobs, growth and economic opportunity in local communities!
