If all the plants on earth died, eventually on the living beings on the planet will also die. Human beings and other animals need plants to live. When green plants make food, they give off oxygen. If there is no oxygen, there would be no photosynthesis and hence, no food.

Not possible. Life on Earth depends on plants, algae and fungi. For humanity, all seven billion of us, they are the major source of food, clothing, shelter and medicine.

Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles and pollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.

(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.

If there are no animals in forests, then there will be a lack of Carbon Dioxide which is required by Plants for Photosynthesis. If plants wont be able to do photosynthesis to get food,then they will die, resulting in lack of oxygen in that place, and slowly the Humans and Animals would finish due to the lack of oxygen.

Answer: Because when a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment.

As species disappear, infectious diseases rise in humans and throughout the animal kingdom, so extinctions directly affect our health and chances for survival as a species. The rise in diseases and other pathogens seems to occur when so-called “buffer” species disappear.

Visit a national wildlife refuge, park or other open space . These protected lands provide habitat to many native wildlife, birds, fish and plants. Scientists tell us the best way to protect endangered species is to protect the places where they live.

Tigers. Tigers are recorded to have killed more people than any other big cat, and have been responsible for more human deaths through direct attack than any other wild mammal.

Karelian Bear Dogs

Pit bulls are regularly cited as one of the most dangerous dog breeds. Between 2005 and 2016, Pit bull attacks led to 64.8 percent of all dog-related deaths. Over this decade, this type of dog caused 254 deaths. The number of pit bull attacks and fatalities is not because pit bull breeds are inherently violent.

Because of their small size, domesticated house cats pose little physical danger to adult humans. However, in the USA cats inflict about 400,000 bites per year.

Cats get a bad rap for being the most eager to eat their owners, and anecdotally, some emergency responders say it’s pretty common. When it happens, cats tend to go for the face, especially soft parts such as the nose and lips, says forensic anthropologist Carolyn Rando of University College London.

While the claim that a cat will purposefully suffocate your baby is false, the VERIFY team did find one incident in the United Kingdom in 2000 where a six week old baby died after the family cat fell asleep on his face. Still – Dr. Johnson says that situation is incredibly rare.

And pound for pound, the bite of a jaguar is the most powerful of the big cats, even more than that of a tiger and a lion. The way they kill is different, too. Tigers and lions, and the other large cats, go for the necks or soft underbellies. Jaguars have only one way they kill: They go for the skull.

A Bengal tiger has killed a lion at Ankara Zoo after finding a gap in the fence separating their cages, say zoo officials in the Turkish capital. The tiger severed the lion’s jugular vein in a single stroke with its paw, leaving the animal dying in a pool of blood, officials said.

“7 Most Dangerous cats”

• Tiger – Panthera tigris. The tiger (Panthera tigris) is the largest of all cats.
• Lion – Panthera leo.
• Jaguar – Panthera onca.
• Leopard – Panthera pardus.
• Snow Leopard – Panthera uncia.
• Mountain Lion – Puma concolor.
• Cheetah – Acinonyx jubatus.

But are lions actually brave, or is it just a myth? “They’re the least afraid of anything of all the predators,” says Craig Packer, an ecologist with the University of Minnesota and one of the world’s foremost lion experts. However, the line between bravery and stupidity can be thin, just as with humans.
