Cutting down trees can lead to malaria
One of the most important and overlooked ecosystems in the world is in areas of rapid land conversion, where agriculture is encroaching on wilderness and where wildlife, livestock and humans are in close proximity. When you talk about emerging diseases, that's where they're emerging from. Nipah virus, which was first identified in Malaysia in 1999, is an example. Pig farms were carved out of forested areas, and fruit orchards were planted next to the pig enclosures, which brought pigs into contact with fruit bats, the natural reservoir for Nipah virus. The virus spread to pigs and then to the farmers, and the ones who caught it had a 40 percent mortality

Technology provides us with some answers to the environmental challenges we are facing. Hybrid technologies have recently made it to the auto market, promising more fuel efficient transportation and less greenhouse emissions. Hydrogen fuels are a very promising alternative to the dirty energies we are using today. Ultra-clean and unlimited, it is the fuel of the future.

Renewable energy sources such as photovoltaics, wind and thermal energies and future renewables we can't imagine yet, promise to someday replace the dirty energy coal burning power plants used throughout the world today, maybe sooner than later for the residential communities.

Although technological advancement does have promises, it does not and will not get us out of

Sustainability? I don't believe there is such a thing anymore. If we were to sustain our current rates of consumption, habitat destruction, emissions, etc. the Earth's biosphere will collapse within a century.

The concept of sustainability at this point is flawed. It is now not a matter of "sustainability", it is a matter of retreat. We need to drastically reduce consumption, drastically reduce emissions, halt all critical habitat destruction, reduce an exponentially growing human population, end industrial pollution, end the expense of war in both monetarily and human life, and educate the world.

We need to rebuild a vast network of environmental habitats linked continuously throughout continents. We need to dive headlong into clean
