The world is in a serious crisis as a result of increase climate change problems ,desertification, deforestation,environmental degradation, and the current one Corona-virus outbreat across the universe (zoonotic diseases)
The emergence of tropical diseases in the universe has poses a great challenges to the existence of plants ,animals and all the living organism in the environment.
Slums are a big worry as a lockdown will not work there and the highly contagious virus can spread rapidly, posing a danger to cities as well.
The coronavirus is upending everything from aviation to the economy — and it’s also having a big impact on the environment.
Climate change is already affecting Forest species including infectious disease agents and greater changes are expected.
Some infectious diseases are already increasing but future changes are difficult to predict because of the complexity of host – agent – environment relationships.
It is clear that ,The world battled a pandemic that seemed potentially more dangerous than any other infectious disease in a century.
Infectious diseases are scary because they are immediate and personal. They radically and rapidly change how we lead our lives, and they are an immediate threat to our friends and families. They hit all of our “go” buttons.\
Global warming, along with population growth, is a factor that is likely to increase that contact. Animals that lose their natural habitats through climate-related phenomena such as fire, or that migrate as temperatures get higher, will probably move increasingly into the human space in search of food.
Climate change will have significant impacts on biodiversity. Disease agents of species that benefit from warming will likely become more prevalent.
Host species stressed by changing envi-ronmental conditions may be more vulnerable to disease agents.
People will continue to move into wildlife spaces such as forests to farm. Either way, the contact is likely to increase.
Many emerging infectious diseases are the result of animal-human contact(Zoonotic diseases)
Viruses can be expected to increase with global warming as humans and wild animals are forced into closer contact,
Climate change seems to many an armageddon in slow motion and its dangers can feel impersonal and its causes diffuse.
It’s easy to think “I didn’t cause this” or that “it doesn’t directly affect me.” But there’s another way to look at it. Like COVID-19,
if you’re concerned about climate change, you can take actions right now to improve your health and the health of your friends and loved ones.
We can learn from this pandemic that people are motivated by the personal and the actionable.
At Harvard C-CHANGE, our research shows that the actions we need to combat climate change are the same actions we need to make people healthier right now, especially for diseases causing huge burdens on our health like obesity, heart disease, and cancer.
We need to do much more to talk about the “burden of disease” that’s preventable, and the things we can do now to prevent it.
The WHO has warned categorically that climate change, along with other demographic, social, and technological changes, will affect infectious disease occurrence.
That includes vector-borne diseases, responsible for more than 17% of all infectious illnesses and more than 700,000 deaths annually.
In a nutshell, A number of environmental factors influence the spread of communicable diseases that are prone to cause epidemics. The most important of these are: water supply,sanitation facilities,food, climate.
