Why species disappear

Read the text. Hover over the dotted words for help.

Why do species disappear?

In 2019, an international scientific report estimated that around one million animal and plant species are threatened with extinction. This number is an estimate, and it covers many different kinds of living things, including insects and plants. Not all of them will disappear soon, but many could vanish in the coming decades if nothing changes.

The report listed five main causes: changes in the use of land and sea, for example deforestation and farming; the direct use of animals and plants, such as hunting and fishing; climate change; pollution; and invasive species. In most places, several causes work together.

Extinction is not new, and the Earth has lost species before. The dodo, a bird from the island of Mauritius, disappeared in the 1600s, after people and the animals that came with them arrived on the island. What is different today, scientists say, is the speed of the loss.

There are also success stories. In 2016, the giant panda was moved from "endangered" to "vulnerable" in an international list, because its numbers had grown after habitat protection. If rules are strong and people support them, species can recover.

Unless we protect habitats, more species will be lost. As long as there are places for wild animals to live, there is hope.

Which animal would you like to see protected?

3.2

True or false?

  1. The number of one million species is an estimate.
  2. The report names only one cause.
  3. The dodo disappeared in the 1600s.
  4. The giant panda was moved to a less serious category.
  5. The text says that nothing can be done.
3.3

What do you think?

  1. Why should we care about species that we never see?
  2. Is it right to spend money on animals when people have problems?
  3. What is the most serious threat for wildlife in your region?
  4. How can ordinary people support conservation?

Grammar for speaking

Zero and first conditional

Zero: if + Present Simple, Present Simple, for general truths. First: if + Present Simple, will + verb, for real future possibilities. Unless means if not, and it is used with a positive verb. Do not use will after if.

If a habitat is destroyed, animals lose their home. If we protect forests, many species will survive. Unless we act, more species will disappear.

Second conditional and as long as

Second: if + Past Simple, would + verb, for unreal or unlikely situations. As long as and provided that mean only if a condition is true.

If I were in charge, I would create more reserves. If nobody stopped it, the species would vanish. As long as there is food, they can survive. Provided that hunting is controlled, numbers can recover.

Block 7 review

Use the grammar from this block.

passive in different tenses (L31) · continuous, perfect and reporting passive (L32) · linking words (L33)

Common mistakes: no will after if, if + past for the second conditional, and unless already has a negative meaning. ✗ If we will protect forests → If we protect forests. ✗ Unless we don't act → Unless we act.
