Mr. Logan: Thank you, Nam. As you know, an ecosystem includes living
and non-living things, and each of them plays an important role. A healthy
ecosystem brings many benefits, such as cleaning our air and water, providing
food and controlling climate change. But human activities are damaging our
planet's biodiversity. Half of our coral reefs have disappeared and it's believed
that 90% of the world coral reefs will die by 2050 due to warming oceans and
pollution. We've cut down one third of the world's forests to make space for
farming or houses. As a result, many animals and plants have lost their
habitats, and many species are disappearing.
Nam: So people are destroying the balance of local ecosystems, aren't they?
But this in turn will affect human life.
Mr. Logan: That's right. One day we may not have fresh air to breathe or
water to use. This may happen if we damage the fine balance among all living
and non-living things in the ecosystems. As species disappear, the food chain
may break down. We may run out of food, suffer from health problems, and
face more natural disasters. So what can we do to restore ecosystems?
