However environmental problems are no longer local, but global, with likely irreversible effects. The synergistic effect of altering climates and environmental fragmentation is a potentially serious problem.

Heatwaves, droughts, floods - that is just a hint of what's in store for a hotter planet

Article Abstract:

The impact of the man's alteration of Earth's environment have resulted in changes such as global warming, deforestation, and ozone depletion in the stratosphere. These, in turn, affect our health through increased natural disasters such as flooding and drought, more heat-related deaths, and more areas affected by infectious diseases such as malaria.
