ACTION IS NEEDED NOW
umanity is approaching a crisis point with respect to the interlocking issues of population, environment, and development. Scientists today have the opportunity and responsibility to mount a concerted effort to confront our human predicament. But science and technology can only provide tools and blueprints for action and social change. It is the governments and international decision-makers, including those meeting in Cairo next September at the United Nations International Conference on Population and Development, who hold the key to our future. We urge them to take incisive action now and to adopt an integrated policy on population and sustainable development on a global scale. With each year's delay the problems become more acute. Let 1994 be remembered as the year when the people of the world decided to act together for the benefit of future generations.
