Previously, the issue of climate change was only discussed partially, but presently, it is dawning on people that climate change is real, and with it comes a lot of consequences for the human race. Other than calamities such as storms, floods, and wildfires, the health of the human race is at stake. I think the greatest health consequences for society in the next 20 years due to environmental changes will be a rise in infectious as well as chronic diseases.
Natural habitats are continuously destroyed as a result of increased human pressure and industrial activities. Deforestation activities already have reduced the forest cover of the world, and most water catchment areas have since dried up. The decrease of forest cover has also interfered with the carbon cycle, hence leaving people exposed to harmful gases. On the same note, industrial emissions and gases in particular, have caused global warming. The increased heat could likely lead to skin cancer, which is a chronic condition. Subsequently, as more harmful gases are concentrated in the atmosphere, people inhale them, exposing them to respiratory conditions. In some cases, some animals and plants trap harmful microorganisms and when they become extinct in the coming years, they will leave human beings vulnerable.

Water bodies and soils in the coming years will be polluted by chemicals on a large scale. The water will be unsafe for drinking while food will be contaminated. One can expect the rise of highly contagious diseases such as cholera especially in the developing countries. Besides, the high chemical content in food could cause cancer. Presently, high cases of cancer are a clear indication of the crisis, which might occur in the next 20 years. While prevention efforts are important, all people in the healthcare industry need to develop strategies to prepare for these health consequences.
