Rearrange the following words and phrases to from meaningful sentences

1- consumed /as / group,/ more and more of / Earth's / the / resources / are / human population / the

2- that have / Earth's history / mass extinctions / the / threatens / periodically during / occurred / the / and / to surpass

3- one everyday / scientists / that / estimate / rate of / species are disappearing / the / at

The answer posted by Param is absolutely correct. There seems to be an error in the question sentence 1. The word 'group' must be replaced with 'grows'.

1) As the human population grows more & more of the Earth's resources are consumed.

2) And threatens to surpass the mass extinctions that have occurred periodically during the Earth's history.

3) Scientists estimate that species are disappearing at the rate of one everyday.

@Param: Good work!
