1 Look, listen and read. Plants make their own food. They use light, minerals and carbon dioxide.
Nutrition in plants
1. The roots absorb water and minerals from the soil.

1 Look, listen and read.
When we take natural resources from the environment and use them, we change ecosystems.
We damage ecosystems when we…
… use all the resources. … cause pollution. … occupy lots of space.
When we consume resources too fast, they can’t recover. This is called over-exploitation.
Human activities pollute ecosystems with smoke, plastic, noise and light.
2 Match the sentences to the pictures in your notebook.
Cities, roads, industries and farms use lots of space. We don’t leave a lot for other living things.
a) We consume coal too quickly. Ecosystems take millions of years to produce more.
b) We hunt animals and catch fish that are endangered.
c) We cut down too many trees. Trees take many years to grow.
d) We destroy the habitats of plants and animals when we build roads.
e) Toxic emissions from industry pollute the environment.
f) The light and noise from campsites disturb animals.

Air pollution is a big problem! The Earth’s atmosphere and the seas are also getting warmer. This is called global warming. All these things are causing climate change.
Some species of living things are extinct. Other species, like the Greek tortoise in Almería and Murcia, are endangered. Fires, uncontrolled urbanisation and unsustainable farming methods are some of the causes.

• Recycle paper, cardboard and packaging.
• Collect toys and give them to charity.
• Turn off taps when you aren’t using them.
• Turn off lights when you aren’t using them.
b) Design a logo for each action. Keep them simple. People need to understand their meaning.

Non-living things: the air, the sun, climate, water and rocks.
Relationships: the main relationships are feeding relationships.

Maria is very observant and very curious.
