The only problem with Bidenâs history lesson is that the âman with steel in his spineâ he referred to should have been George W. Bush, not Barack Obama. Lest we forget, it was Bush rather than Obama who initiated the government rescue of the auto companies.
* The Pilosocereus cactus is native to Brazil and can grow up to 20ft in height. * The giant Saguaro cactus is the world's tallest, growing up to 67ft high, weighing six tonnes and can live for 250 years. I takes 50 years to produce its first flower.
The 2,000 species of cacti are known for living in extremely dry climates, such as the American Southwest. Cacti are excellent at conserving water. Their leaves are sharp spines, which have been known to cause great pain to animals interested in eating them. The spines also help the plant gather scarce water. Water vapor in the air condenses on the spines and then drips to the ground, where it is taken up by the roots.
