Habitat destruction forces wildlife into human environments, where new diseases flourish
“It’s a mix of biodiversity, but one that was created by people, not nature,” Keesing says. “We create a mix of species that don’t naturally occur together, and then it’s kind of like running an uncontrolled experiment. This virus jumps to that species.” Maybe that’s when a pathogen that we didn’t know about, that hadn’t previously made anyone sick (to our knowledge), suddenly becomes virulent and infects humans. “It was only when we did that to biodiversity that that virus became dangerous.” These types of markets pose one of the clearest threats to animal and human health, but they’re not the only threat. A greater risk is posed by the complex mix of habitat loss, population declines in wild species, and population increases among livestock and domesticated animals, invasive species and other more adaptable forms of wildlife.

And look for more disease as environment is disrupted 🥵
About 75% of counties on the US mainland have suitable habitat for Aedes mosquitoes, CDC researchers say.
Italy was officially declared free of malaria in 1970, but environmental organization Legambiente warned in 2007 that it could make a comeback due to the effects of climate change.In particular, warmer temperatures have brought mosquito species including the Asian Tiger mosquito, known to transmit several diseases, to Europe. In recent years, the first EU cases of West Nile fever were detected in Italy as well as Romania, while Ravenna in the north of the country experienced an outbreak of Chikungunya fever in 2007. was also detected in Italy. Both diseases are known to be transmitted by Asian Tiger mosquitoes.
Texas health officials today announced the state’s first probable local Zika infection of the year, which also appears to be the first local case reported in the United States for 2017.The patient is a Hildago County resident who had not traveled outside the area or had any other risk factors, the Texas Department of State Health Services (TSDHS) said in a press release. Hildago County, located in the Rio Grande Valley, is in far southern Texas on the border with Mexico.The virus was probably transmitted by a mosquito bite in South Texas some time in the last few months, and lab tests show that the person is no longer at risk of spreading Zika to mosquitoes.In April the TDSHS expanded its recommendations for testing pregnant women and people with Zika infections in six South Texas counties, which led to thousands of tests being conducted and to the identification of the newly identified case.
So far, yellow fever is currently being transmitted by two types of mosquitoes on Brazil, the Haemagogus or Sabethes. If yellow fever is introduced to a major urban center, the virus could jump to the Aedes aegypti mosquito, making human transmission more likely.”There is no evidence of human cases of yellow fever virus infection transmitted by Aedes aegypti, the vector that could sustain urban transmission of yellow fever,” the WHO said in its update.
“This is a fivefold increase in less than 1 month,” said Duane Gubler, ScD, MS, former director of the US Centers for Disease Control and Prevention’s (CDC’s) Division of Vector-Borne Infectious Diseases. “That’s an unusual number for sylvatic yellow fever.”
The two technologies could be “transformational,” said Dan Strickman, a senior program officer at the foundation. The next challenge, however, will be to identify the approaches that work best in combination with existing medical treatments so as to shrink the footprint of the disease over the next ten to fifteen years, Karl Malamud-Roam, manager of Rutgers University’s public health pesticides program, told the Seattle Times.
Finding out how human behavior facilitates the expansion of growth of malaria carrying mosquitoes would cost less but would show that industrial farming and deforestation are the chief facilitators of malaria’s continual comebacks.
That is to say, as humans continue to reshape the state to fit our desires, we are creating the conditions for a mosquito population explosion. To make matters worse, the channel reports that species capable of carrying the West Nile virus and Zika do well in California’s human-made environment. And scientists expect it to only get worse.”Urbanization, driven by human population growth and movement, has been a major driver of environmental change during the last century and is projected to increase substantially in the future across the globe,” the study authors write. “Our results suggest that urbanization is likely to drive additional changes in mosquito communities, including the expansion of habitat for urban mosquitoes.”
