Would you tell me what flooding valleys mens? and why flooding valleys are bad things like cutting trees?
A IT is an unquestioned principle that has dominated international thinking for decades: we live in an overcrowded world teeming with billions of humans who are destined to suffocate our cities and squeeze our planet of its precious resources. Our species is inexorably wrecking Earth: flooding valleys, cutting down forests and destroying the habitats of animals and plants faster than scientists can classify them.
Thanks in advance
