Natural features include beaches, deserts, mountains, rainforests, and savannas.

Grasslands are estimated to constitute 20 of the vegetation cover of the Earth.

You are a hominid three million years ago walking on the plains of Africa.

So those of you who are going on one of the post conference tours, you'll get to see what a real savannah is like.

Geography Ashantiland has a variable terrain, coasts and mountains, forests and grasslands, lush agricultural areas and near deserts.

Now I said back in our little thought experiment, you're a hominid walking on the plains of Africa.

The example of the use of the Brazilian cerrado, once considered useless, augurs well for the African savannas.

The rainforest has been in existence for at least 55 million years, and most of the region remained free of savanna type biomes at least until the current ice age, when the climate was drier and savanna more widespread.

The Old World monkeys are native to Africa and Asia today, inhabiting a range of environments from tropical rain forest to savanna, shrubland and mountainous terrain, and are also known from Europe in the fossil record.

Animals Numerous mammals are found in the bushveld including lions, leopards, white rhinos, blue wildebeest, kudus, impalas, hyenas, hippopotami and giraffes.

Most of the CAR consists of Sudano Guinean savannas, but the country also includes a Sahelo Sudanian zone in the north and an equatorial forest zone in the south.

The different climatic conditions produce environments ranging from equatorial rainforests in the north and semiarid deserts in the northeast, to temperate coniferous forests in the south and tropical savannas in central Brazil.

I've often wondered, what is the evolutionary pressure that made our ancestors in the Veldt adapt and evolve to really enjoy pictures of galaxies when they didn't have any.

People in very different cultures all over the world tend to like a particular kind of landscape, a landscape that just happens to be similar to the pleistocene savannas where we evolved.

People who would have specialized in killing the animals, hunting the animals on those meat locker savannahs, moving up, following the grasslands into the Middle East around 45,000 years ago, during one of the rare wet phases in the Sahara.

And, indeed, once again we're moving forward to the kind of sexual expression that we probably saw on the grasslands of Africa a million years ago, because this is the kind of sexual expression that we see in hunting and gathering societies today.

尽管人均作物产量仍将下降 但全球适耕土地数量比先前估计的要多 比如 巴西塞拉都 cerrado 原本认为无法耕种 但也已经开始使用 这对于非洲稀树草原来说是个福音 未使用土地储备也存在于南美 中亚和东欧各处

And you need the local people for that because these grasslands, once they start burning ... It goes through it like a windstorm and you lose again the last bit of ash and nutrients to the first rainfall going to the sea killing off the coral reefs there.

This is what's really complicated, that there were people living in places like the Grand Canyon, cooperating with each other, or on the savannahs of Africa, or on the frozen shores of Alaska, and then some of these villages grew into the mighty cities of Babylon, and Rome, and Tenochtitlan.
