Complete the text about global warming.
the biggest environmental problem we face
today is global warming. if we (continue)
continue to burn gas, coal and oil, the
atmosphere (contain) will contain more co2,
so the world will get warmer. if it (1 get)
warmer, sea-levels (2 rise) and the
climate (3 change)
trees help to stop global warming because
they change co, into oy. however, unless we
(4 stop) cutting down the rain forests,
there (5 more co, in the atmosphere
and global warming (6 not get) better.
so we must preserve forests like the amazon
the holes in the ozone layer are another
problem. the ozone layer protects us from
ultra-violet rays from the sun. if the holes
(7 get) bigger, the ultra-violet rays
(8 make) the atmosphere hotter.
global warming is getting worse every day.
we (9 not solve) this problem unless we
(10 act) now.​
