Global Warming Called Health Threat

Global warming is the biggest health threat of this century, a group of experts has warned. The group said malaria and other diseases spread by insects could become more widespread as the earth gets warmer. Heat waves could kill more people. Crop yields could decline and cause hunger. Climate change also could cause flooding that overwhelms sewage systems, the experts said. They called for laws to restrict carbon emissions. They said health professionals should get involved in the fight against global warming. The experts issued their warning in a news conference. Their report was published in the journal Lancet.
