Effects of human development globally
Human Development leads to serious global issues like environmental and human problems. Human beings have been living in the world for many years and the world has been a clean and conducive place for them until they realized that they need to satisfy other needs. In their attempt to satisfy these needs, human beings ends up messing with the way the world was meant to be by over exploiting the resources available.
Search for energy, innovation, increase in knowledge and need to satisfy other needs has lead the humans to perform some activities that are harmful to the whole world. The most effects of these activities include global warming and pollution. Through burning fossil fuel in search for energy, harmful gasses are emitted into the atmosphere. These gases are also produced a bi-products during manufacture of other products in industries.
Global warming is caused by the accumulation of carbon dioxide in the atmosphere which destroys the ozone layer which regulates the amount of sun heat that reaches the earth. This interferes with the normal climate of the world making it extremely hot and the seasons change. This affects the normal functioning of all activities of the world especially in the places that are vulnerable to changes in climate.
Vegetation which absorbs carbon dioxide during gaseous exchange has been cleared, especially forests. This is to accommodate the high population and to create room for production of food to feed this highly increasing population. These forests are mostly the sources of clean water found in rivers. This makes some people lack access to clean water. It also means that there is a very higher rate of production of carbon dioxide than its absorption level. CITATION uni11 \l 1033 (scientists)
Global warming causes high temperature on the world. Water levels in seas and oceans increases displacing those who live along coastal region. This change in climate affects the mode of pathogen infections, their geographical distribution and their behavior. This also makes them resistant. Vector organisms like mosquitoes will spread diseases which will be vey fatal under global warming conditions.
Changes in climate will highly affect the humans in terms of food production especially those who depend on food substances which are sensitive to climate. This means that food supply is less compared to the highly increasing population.
Floods, rise in temperature and lack of clean water can cause waterborne diseases. This will reduce child mortality rate and raise early childhood deaths. Clean water in rivers is reducing leading to low supply of clean water. This means that there are very many people who lack access to clean water pausing health threat to them.
