All corporations are at first driven by their debts to expand their business to attract as many customers as possible. Then, if they're successful, greed drives them to pay their CEOs big salaries and bonuses, and more people invest when they see the corporation grow. Everyhing would be fine if only the Earth could grow right along with them -- but it's not. Instead it's slowly shrinking with each volcano and earthquake and each ton of coal, oil, natural gas and all the other minerals they dig up 24 hours a day, 365 days a year all around the World. So, how many people and how much industrial expansion can the Earth maintain before its life-support systems collapse and all the species go extinct? I think we will soon find out.
