Recognizing that the requirements of land and climate for species survival can provide a basis for regulating human food production and protecting species to the greatest extent. Scientists have concluded through investigations that when rainforests are cut into farmland, birds that need humid climates Tends to die, and those who adapt to arid climates survive. Which of the following, if true, would best support the scientists' conclusions? ['Birds adapted to dry climates are better able to adapt to future climate changes and future land use changes.', 'The natural conditions of farmland are similar to the natural conditions of bird habitat in arid climates.', 'It is necessary to preserve protozoan habitats in arid regions to buffer the impact of climate change.', 'When converting animal habitat into farmland, one must consider current and future climate conditions in the area.']
