People in rich developed countries tend to think of climate change as a threat to our future, but communities in developing countries are feeling its effects right now.
Poor people are most vulnerable to changes in their environment, with many of them living in fragile housing conditions on marginal land. Often they rely heavily on agriculture, and lack savings or insurance to recover from disaster-related incidences.
Many scientific reports tell us that we must keep global temperature rise below two degrees to avoid catastrophic climate change. But communities in the developing world are already suffering from the pinching effects of climate change, pushing poor people even deeper into poverty.
In such communities, the effects of climate change are clearly visible all around, and evident in the lack of rainfall, of people having to walk longer distances to access drinking water, of too much rainfall bringing floods and washing away crops and homes, and in a rise in sea levels as a result of warming oceans, unusual and erratic rainfall which can cause crop failure, leading to hunger and loss of livelihood, as well as rapid increase in malnutrition.
Also there is increased prevalence of malaria, as mosquitoes spread to new areas, more environmental refugees, and mounting pressure on vulnerable regions leading to tension and conflict.
Thus, the emergence of organisations working to ensure that communities who will be most affected by climate change are able to adapt to changes to their environment where this is possible, and are better prepared for natural disasters.
But if reducing poverty is a moral obligation, as millions of persons who donate faithfully to charities readily accept, it is also a matter of sheer national self-interest.
Ultimately, the grinding persistent poverty that afflicts far too many Africans affects all of us. It forces up our tax bills, depresses the economy, increases health costs and can breed alienation and crime.
The correlations between poverty, social class and poor educational experience and attainment have been clearly established.
Poverty affects the likelihood of progressing through school to attain formal educational qualifications.
Children from poorer backgrounds are more likely to play truant, and to be excluded from school. Access to and completion of higher education is significantly affected.
However, poverty should not be a license for anyone to steal or take someone's life. Instead, one should work hard to overcome poverty.
