How Mova does on its tests: [the lesson at school](https://md.mova.elamur.ai/free/en/school-run/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/). - [0](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/0/) — Scientists are trying new ways to look after life on Earth: freezing the cells of rare animals, building bridges for deer over roads, growing meat without farms, and even making elephants that look a little like mammoths. - [1](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/1/) — In Jurassic Park, scientists find dinosaur blood in a mosquito trapped in amber and bring T. rex back. - [2](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/2/) — It is a great story, but DNA breaks down over time, and after 66 million years no usable dinosaur DNA is left. - [3](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/3/) — The planet is also changing: as places warm, many plants and animals move towards the poles or up mountains, like children shifting along a bench into the shade on a hot day, until someone at the very end has nowhere left to go. - [4](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/4/) — Nobody knows exactly what life will look like in millions of years, but the next hundred years depend a lot on what people choose to do now. - [5](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/5/) — A company is trying to add mammoth genes to Asian elephant cells to make a cold-adapted elephant; it would be a new kind of elephant, not a true mammoth, and in 2025 it was reported to have made woolly mice with long golden hair as a test. - [6](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/6/) — In 2025 a company was reported to have made wolf pups with some genes changed to look like the extinct dire wolf; they are grey wolves with white fur and a few changes, and scientists disagree about calling it de-extinction. - [7](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/7/) — T. rex cannot be cloned, because cloning needs DNA and dinosaur DNA is long gone; birds are living dinosaurs, so a bird is the closest we can get. - [8](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/8/) — As places warm, many plants and animals move towards the poles or up mountains, and some cannot move fast enough or have nowhere higher to go. - [9](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/9/) — Corals turn white, which is called bleaching, when the water is too hot and they push out the tiny algae living in them, which get a home in the coral and make food from sunlight for it; without the algae they starve, though they can recover if the heat passes. - [10](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/10/) — Scientists breed tougher corals and plant them back on damaged reefs. - [11](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/11/) — Frozen zoos keep cells, eggs and sperm of rare animals in liquid nitrogen, which may help to breed more animals later; the northern white rhino, with only two females left, may be helped this way. - [12](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/12/) — In 2022 countries agreed on a goal called 30 by 30: to protect 30 percent of land and sea by 2030, which needs money and work with local people. - [13](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/13/) — Green bridges are bridges over roads covered with soil and plants; they let deer, bears and other animals cross safely, and in Canada's Banff National Park they cut the number of animals killed on the road sharply; on Christmas Island, where millions of red crabs cross the roads each year, the crabs have their own small bridges so they are not squashed. - [14](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/14/) — Scientists can grow meat from animal cells in tanks without raising whole animals; it is sold in a few countries, it could use less land, but it is still expensive. - [15](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/15/) — Scientists look for life on Mars and on moons such as Europa and Enceladus, which have oceans under ice; on Earth life survives in boiling vents and frozen lakes, but no life beyond Earth has been found yet. - [16](https://md.mova.elamur.ai/free/en/corpora/school/biology/297-the-future-of-life-de-extinction-climate-coral-and-frozen-zoos/16/) — No one knows what animals will look like in millions of years, because evolution follows changes nobody can predict; after every great extinction in the past, life made new kinds. - ← previous: [Animals in the news: true stories, fakes and how to read them](https://md.mova.elamur.ai/free/en/corpora/school/biology/296-animals-in-the-news-true-stories-fakes-and-how-to-read-them/) - next →: [The big biology quiz, part 1: habitats and animals](https://md.mova.elamur.ai/free/en/corpora/school/biology/298-the-big-biology-quiz-part-1-habitats-and-animals/) - ↑ back to [Biology](https://md.mova.elamur.ai/free/en/corpora/school/biology/)
