Common outcomes are excessive algal growth ( or algal blooms ) insurface waters , oxygen depletion , enhanced growth and dominance of some species that grow better with higher nitrogen conditions and reduced growth of others , resulting in ecosystem imbalance and a decline in species richness . Ironically a possible factor in the failure of the expedition was the indiscretion of Giuseppe Mazzini , compiler of this account , who , believing that there was no postal censorship in Britain , mailed details of the plot to another Italian revolutionary in London . African governments must show greater political will and commitment to solving environmental problems , and must be prepared to devote their own financial and human resources to practical environmental action . It is important to note that people in all regions in the world are vulnerable in one way or another to environmental change , but that their coping capacity is different . Figure 5.1 and Figure 5.2 show the impacts of policy responses that improve accessibility to safe water and sanitation services . Another is that some products of incomplete combustion – particularly methane and black carbon particles – are even more powerful greenhouse pollutants than carbon dioxide , and therefore have higher global warming potential . Conversely , some areas experience lower than average rates of population growth , due to below-average intrinsic rates of population increase and to emigration . Desertification is another serious concern in Africa , particularly in the more arid zones where climate variability and poor land management practices combine to threaten the sustained productivity of soil and vegetation . Trade Organization Ministerial Conference , rich countries agreed to end export subsidies for cotton by the end of 2006 and for all agricultural products by 2013 .

Although the form of this support will clearly vary from technology to technology and from country to country , depending on the overall policy framework in place , it is an essential ingredient in the widespread increase in renewable energy use . Virtually all national governments advance a package of policy adjustments , which include : modernization of financial systems ; investment in education to create a workforce that is competitive in the emerging global market ; privatization ; reduced social safety nets ; and , in general , reliance on market-based approaches . Broadly , our agenda is to give a human face to environmental issues ; empower people to become active agents of sustainable and equitable development ; promote an understanding that communities are pivotal to changing attitudes towards environmental issues ; and advocate partnership which will ensure all nations and peoples enjoy a safer and more prosperous future . Studies also show that the actual costs of measures may be less than the predicted costs . Twenty years on , the upbringing of a young lady in South Carolina remained remarkably similar to Angelica 's own , including attending a finishing school , yet Mary Singleton 's books show also a significant new interest in works by women authors and about women 's issues .
