One understands from the passage that the development of tree species that can resist droughts ----.
Government planners and social scientists from
many countries are developing a number of
strategies to help us adapt to global warming. For
example, what should people living in coastal areas
do? They can move inland away from the dangers of
storm surges, although this solution has high
economic costs. An alternative plan, which is also
extremely expensive, is to build dikes to protect
coastal land. The Dutch, who have been doing this
sort of thing for several hundred years, have offered
their technical expertise to several developing nations
threatened by a rise in sea level. We also have to
adapt to shifting agricultural zones. Many temperate
countries are in the process of evaluating
semitropical crops to determine the best ones to
substitute for traditional crops if or when the climate
warms. Drought-resistant species of trees are being
developed by large lumber companies now, because
the trees planted today will be harvested many
decades later when global warming may already get
much worse.
