This situation is exacerbated by the massive debt burden which affects developing countries, notably in Africa. Environmental protection is often one of the first things to be cut back to finance interest payments. Globalization is a concern at a number of levels. From a purely practical point of view, it drives global demand for an unsustainable level of consumption. Clearly, improved living conditions are highly desirable if sustainable.
Biological globalization is also a concern.
Travel and trade allow organisms to move around the world and invade new environments - sometimes on purpose, sometimes by accident. Many varieties and breeds, often evolved over centuries of local selection, have desirable features that adapt them to particular local environments, resisting specific diseases and environmental extremes. Such diversity may be the answer to sustainable agriculture. International trade, like globalization, cannot be divorced from environmental concerns. Clearly, trade can increase wealth for many countries - which is part of the reason why the world is moving headlong towards increased trade liberalization.
