1 . Tropical rainforests (热带雨林) are home to native peoples who rely on their surroundings for food, shelter, and medicines. Today very few forest people in many areas like the Philippines, Papua New Guinea live in traditional ways; most have been displaced by outside settlers or have been forced to give up their lifestyles by governments.

Of the remaining forest people, the Amazon supports the largest native or native populations, although these people, too, have been affected by the modern world. While they still depend on the forest for traditional hunting and gathering, most Amerindians, as American native people are called, grow crops, use western goods, and make regular trips to towns and cities to bring foods and products to market. In Africa there are native forest people sometimes known as pygmies. The tallest of these people, also called the Mbuti, are not more than 5 feet in height. Their small size enables them to move about the forest more quickly than taller people.

Tropical rainforests have supported humans since ancient times. Although forest life cannot be described as easy, these peoples have built their lives around the surrounding forest and its systems. Still, these forest people can teach us a lot about the rainforest. Their knowledge of medicinal plants used for treating illness is valuable, and they have a great understanding of the ecology (生态学) of the Amazon rainforest. As a result, they are a great storehouse of the knowledge about the forest. They know the medicinal functions of plants and understand the value of the forest as an undamaged ecosystem. As forests fall, these native peoples lose their homes and culture, resulting in the drop of the native population.

2 . Nola (August 21, 1974—November 22, 2015) was a northern white rhino who lived at the San Diego Zoo Safari Park near Escondido, California. At her death, she was one of only four remaining northern white rhinos in the world. The other three lived in Kenya. World Rhino Day,   held on September 2,   is to raise awareness(意识) of the less than 30, 000 other rhinos left on Earth.

''Rhinos need our help today, not tomorrow,'' Nola's lead keeper Jane Kennedy said. ''Last year we lost over 1, 200 rhinos just in South Africa. If we continue to lose more than 1, 000 rhinos a year, in 10 to 20 years all the rhinos on the planet will be gone. ''

''Unfortunately, most animals are in danger of dying out because of humans,'' Kennedy says. ''Humans have either poached animals, or because there are over seven billion of us, we've taken up too much of the world's resources''. Poachers illegally hunt rhinos for their horns. They sell the horns for thousands of dollars per pound, to be used for art, jewelry, and decorations. Experts believe that one rhino is poached every eight hours.

In 1975,   the San Diego Zoo Institute for Conservation Research started the Frozen Zoo,   a program through which researchers have collected cell (细胞) samples from more than 8, 000 different types of animals,   including the northern white rhino. Scientists hope that by studying the rhino cells, they will get greater understanding of it, and will find ways to increase its numbers.

Jane Kennedy describes World Rhino Day as a celebration of rhinos along with an awareness campaign for everybody across the world to know that rhinos need our help. ''At the San Diego Zoo, children and adults are welcome to visit and speak with zookeepers to learn about rhinos. But you don't have to live in San Diego to celebrate World Rhino Day. It is observed around the world, with zoos and wildlife parks holding special events and programs to teach people about rhinos, and enable them to see the animals up close.

Choose to eat local.

Many travelers want to visit local homes and taste home cooked meals. Eating locally made a good influence（影响）on a country.
