probably the most famous name associated with wwf is hrh the duke of edinburgh. the duke was the first president of wwf-uk from its foundation in 1961 to 1982, international president of wwf (1981-1996), and is now president emeritus.wwf is dedicated to stopping the degradation of the planet’s natural environment and building a future in which humans live in harmony with nature, by:▲ conserving the world’s biological diversity, ▲ ensuring that the use of renewable natural resources is sustainable, ▲ promoting the reduction of pollution and wasteful consumption. wwf has a factual, science-based approach to conservation, which focuses on six priority issues of global concern: forests, oceans and coasts, fresh water, endangered species, and the insidious threats of toxic chemicals and climate change. for each of these issues, wwf has developed measurable targets and runs more than 1,200 field projects around the world in any year.iii. antelopethe antelope are a group of herbivorous african animals of the family bovidae, distinguished by a pair of hollow horns on their heads. these animals are spread relatively evenly throughout the various subfamilies of bovidae and many are more closely related to cows or goats than each other. there are many different species of antelope, ranging in size from tiny to very big. they typically have a light and elegant figure, slender, graceful limbs, small cloven hoofs, and a short tail. antelope have powerful hindquarters and when startled they run with a peculiar bounding stride that makes them look as though they are bouncing over the terrain like a giant rabbit. some species of antelope can reach speeds of 60 miles per hour (100 kilometers per hour), making them among the fastest of land animals.iv. elephantelephantidae (the elephants) is the only extant family in the order proboscidea. elephantidae has three living species: the savannah elephant and forest elephant (which were collectively known as the african elephant) and the asian elephant (formerly known as the indian elephant). during the period of the ice age there were more species, which are now extinct.elephants are the largest living land mammals. at birth it is common for an elephant calf to weigh 100 kg (225 pounds). it takes 20 to 22 months for a baby elephant to mature to birth, the longest gestation period of any land animal. an elephant may live as long as 60 to 70 years. the largest elephant ever recorded was a male shot in angola in 1974, weighing 1 kilograms or 26400 pounds. prehistoric human beings have been known to eat elephants, as recent findings of animal remains in central china show. the elephant is now a protected animal, and consumption is prohibited around the world.
