Bamboo and corn are renewable resources, used for various ends. Bamboo is a fast growing crop, making it cheaper than other wood that takes longer to mature. It is also quite durable and engineers are finding more and more uses for bamboo in products.
Corn is used for food, foodstuffs (like "corn syrup") and fuel. Ethanol is made from corn and can be used to power cars (partially or fully).
Typically, the pro of nonrenewable resources is that they are relatively cheap when compared to renewable resources. For example, it is much cheaper at this point to produce electricity using natural gas or coal than it is to produce it using wind power or solar power. So, price is a major pro of nonrenewables and a major con of renewables, at least in the area of energy.
Renewable resources can be grown. They are not finite. Nonrenewable resources are finite, because there is only a certain amount and then they are gone. For example, fossil fuels are non-renewable because we cannot make more of them, but corn is renewable because we can grow more.
