Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen!
How does cutting of trees affect the environment?
Cutting trees can result in the loss of habitat for animal species, which can harm ecosystems. The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.
What if the Earth had no trees?
Life couldnot exist on the planet without trees and plants, because they produce most ofthe oxygen that we need to breathe. It means,no trees and plants….. no humans!

What would Earth be like without humans?
From interviews with members of the Wildlife Conservation Society and the New York Botanical Gardens Weisman predicts that native vegetation would return, spreading from parks and out-surviving invasive species. Without humans to provide food and warmth, rats and cockroaches would die off.
What year will humans go extinct?
If developing world demographics are assumed to become developed world demographics, and if the latter are extrapolated, some projections suggest an extinction before the year 3000. John A. Leslie estimates that if the reproduction rate drops to the German or Japanese level the extinction date will be 2400.
Will humans go extinct in my lifetime?
The short answer is yes. The fossil record shows everything goes extinct, eventually. Almost all species that ever lived, over 99.9%, are extinct. Humans are inevitably heading for extinction.
What would happen if everyone on Earth disappeared?
Roads would turn to rivers, and underground subway systems would flood. Most species that humans have repressed would return to the population levels they were at before humans evolved. Invasive species that humans have imported and exported would continue to thrive in their non-native lands.
Can the earth survive without humans?
Of course, the Earth can and will survive just fine without us. “Nature will break down everything eventually,” says Alan Weisman, author of the 2007 book The World Without Us, which examines what would happen if humans vanished from the planet. “If it can’t break stuff down, it eventually buries it.”
What will happen if animals disappear from Earth?
(a) If the plants and animals disappear from the Earth’s surface, then the ecological balance will be disturbed. Without plants there will be no oxygen available for breathing after some time and everybody will die. These animal and plant species, including humans, are all interdependent.

Is it possible for the Internet to disappear?
It’s possible for parts of the internet to go offline. In fact, this happens all the time.

Is any network ever 100% secure?
An absolutely secure network is not possible, but the risk can be managed. No network can claim to be 100 percent secure. Hackers are clever and motivated to access your network. The best you can ultimately achieve is a stalemate where the risk of invasion is at a manageable level.
What will happen to the world if there is no Internet connection?
With Google itself having 80,000 full-time staff, hundreds of thousands of people would be left unemployed. Even companies that only rely on the Internet as means of advertising would be affected. Developed countries would lose entire industries, and face economic crisis.
