Answer: You could use old documents to help you make new medicine.
Explanation:
Mars' atmosphere is made mostly of carbon dioxide, much like Venus. It is not as hot as Venus because the Martian atmosphere is extremely thin. Venus has a thick layer of carbon dioxide gas surrounding the planet. This is why it is the hottest planet in the solar system even though it is not the closest to the sun. Carbon dioxide is a greenhouse gas so it has the ability to trap infrared radiation. The atmosphere on Mars is thin and so it will not trap as much heat as the Venusian atmosphere.
Remember the saying,
<em>"Give a man a fish and he will eat for a day, teach a man how to fish and he will eat forever"</em>
Well the Gopniks in Russia wrongly translated with saying to: teach a man how to become a fish and he will eat forever. So during the 1970-90s the gopniks all gathered near the lakes in order to satisfy their famine from communist regime. Unfortunately humans can not breathe under water so, fisherman in present day are still recovering bodies from the bottom of these lakes of these gopniks. Thousands still remain in lakes across this nation.
