The threat to the environment
Nowadays people are more aware that wildlife all over the world is in danger
Many species of animals will become extinct if we do not make an / every/ a special.... effort to protect them .
There are many reasons for this
In some cases, animals are hunted for their fur or for other valuable parts of their bodies
Some birds, such as / like parrots, are caught alive and sold as pets.
For many animals and birds the problem is that their habitat - the place where they live - is disappearing.
More land is used for farms, for houses or industry, and there are fewer open spaces than there once were .
Farmers use powerful chemicals to help them (to) grow better crops ,
but these chemicals pollute the environment and harm wildlife .
The most successful animals on earth - human beings - will soon be the only ones left
unless we can solve this/the problem
