We learn from the passage that the Earth will turn into a desert .......

The end of the world really is near. Scientists
studying the fate of the Earth have warned that
the expansion of the Sun will turn the Earth
into a desert in 500 million years, much sooner
than previously thought. Until now,
astronomers have predicted that the oceans will
take five billion years to evaporate as the Sun,
like all stars, becomes brighter, hotter and
eventually implodes. However, a sophisticated
new computer modelling system suggests that
the process will start long before that. This
model predicts that plants — including trees
and most crops — will start dying out in 300 to
400 million years, with 95% becoming extinct
in 500 million years. After another 500 million
years, the Earth's surface temperature will have
reached 60°C and the oceans will have
evaporated into space.
