Reasons (1) The area of Manhataan is composed of solid concrete and nothing can grow there, (2) The atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe and survive (3) The consolidated Edison Belt will give them a lot of trouble. (4) The water is polluted and unfit to drink. (5) There are so many metal particles that it is impossible to land a flying saucer without its being smashed by one They have to take their own oxygen. They have to take their own water It is dangerous.

Fill in the blanks  Scientists on Venus are discussing the feasibility of landing a manned flying saucer on Earth, based on information received from a satellite. Their conclusions are that the planet Earth is unfit for habitation because of its highly polluted condition. For one thing, deadly gases in the atmosphere make it extremely dangerous to breathe. For another, the water, also polluted, has become undrinkable. For these reasons, it would be difficult for anyone to survive on Earth. Undoubtedly the flying saucer program will be set back under these conditions, but the Venusian scientists are determined to proceed with their exploration of the planet Earth

What should we do?  BEIJING — The Chinese government said Thursday that it had set a target to slow the growth of greenhouse gas emissions by 2020, aiming to reduce so- called carbon intensity by 40 to 45 percent compared with 2005 levels even as its economy grows, according to Xinhua, the state news agency
