Quote by Thomas Malthus

"The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race."

"Population, when unchecked, increases in a geometrical ratio."

"That the increase of population is necessarily limited by the means of subsistence."

"The history of mankind will be found to be a history of a struggle."

"Science helps us understand the world."

"I've witnessed the birth of science, and it continues to amaze me."

"I'm something of a scientist myself."

"The fusion process is self-sustaining now!"
