This document discusses several ecological problems facing the planet as a result of human activity, including pollution, habitat destruction, species extinction, deforestation, acid rain, and global warming. It notes that all living things are interconnected and that human activities like burning fossil fuels, cutting down forests, changing land use, and emitting pollutants are negatively impacting the environment and wildlife by destroying habitats, reducing biodiversity, and altering the climate. Urgent action is needed through limiting activities that damage the environment in order to protect the planet.

1. ECOLOGICAL PROBLEMS
Prepared by: Ekaterina Vaskina.

2.  Our planet is home to millions of different kinds of plant
and animal species, which are linked in different ways.
Together, they make up the complex world of nature.
Unfortunately,co-habiting with humans brings up
ecological problems. The most acute are pollution, acid
rain, wildlife destruction, shortage of natural resources
and global warming. These problems are interrelated as
everything in the natural world depends on one another.

3.  Wild plants and animals live in a particular set of
surroundings, called their habitat. Nowadays people
change habitats to suit their own needs - to create
farmlands or build cities, for example. They also destroy
wildlife habitats while mining or by building roads.

4.  A lot of species - fish, reptiles, insects, birds, mammals -
are disappearing fast. It’s reported that by 2030 25% of
all animals, birds and insects may be extinct.

 All living organisms breathe in oxygen, and breathe out
carbon dioxide. We produce carbon dioxide when we
burn things. Trees take this gas from the air, and
produce oxygen. But in the last few years, people have
cut and burnt large amount of rainforest.

5.  Many plants in the world are known to be in danger
or threatened with extinction. The world has over nine
million square km. of forests. Paper and cardboard are
made from wood. Every year over 100000 sq. km. of
forests are cleared for different uses, and a lot of
forests are so badly damaged that they will hardly be
able to recover.
 Acid rain falls when poisonous gases from power
stations and vehicles mix with oxygen and moisture in
the air. Acid rain poisons or kills wildlife in lakes, rivers,
and forests, and damages the surrounding plant life.
The problem could be controlled by reducing vehicle
emissions and limiting the gases released from power
stations.

6.  World temperatures
are currently rising
every year.
This phenomenon is
called global warming.
As the planet warms
up, the water in the
oceans will take
upmore space and
water from glaciers
and the polar ice caps
will start to melt. This
could cause sea levels
to rise and many
habitats will disappear
under water.

7.  Summing everything up, the climate in different parts of
the world changes every year. These changes can be
dangerous for our planet which needs protection. The
measures to be taken include limitations for cutting
rainforests and poisonous gas emissions as well as
personal ecology of humans.
