Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.
In the past hundred years, biodiversity around the world has decreased dramatically. Many species have gone extinct. Extinction is a natural process; some species naturally die out while new species evolve. But human activity has changed the natural processes of extinction and evolution. Scientists estimate that they are dying out at hundreds of times the natural rate.
A major reason for the loss of biodiversity is that natural habitats are being destroyed. The fields, forests, and wetlands where wild plants and animals live are disappearing. Land is cleared to plant crops or build houses and factories. Forests are cut for lumber and firewood. Between 1990 and 2005, the amount of forested land in Honduras, for instance, dropped 37 percent. As habitats shrink, fewer individuals can live there. The creatures that survive have fewer breeding partners, so genetic diversity declines.
Pollution, overfishing, and overhunting have also caused a drop in biodiversity. Global climate change - the latest rise in the average temperature around the globe, linked to human activity - is also a factor. Warmer ocean temperatures damage fragile ecosystems such as coral reefs. A single coral reef can shelter 3,000 species offish and other sea creatures such as clams and sea stars.
