When did Pollution start becoming a major problem?
Along with amazing technological advances, the Industrial Revolution of the mid-19th century introduced new sources of air and water pollution. By the middle of the 20th century, the effects of these changes were beginning to be felt in countries around the world.
What caused pollution?
The Short Answer: Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.
When did humans start polluting the earth?
Some would assign it to the start of agriculture 11,000 years ago, while others tie it to the advent of the nuclear era in 1945, but most recognise the Anthropocene as beginning with the industrial revolution (1780s-1830s).
What killed the dodo bird?
The combination of human exploitation and introduced species significantly reduced dodo bird populations. Within 100 years of the arrival of humans on Mauritius, the once abundant dodo bird was a rare bird. The last dodo bird was killed in 1681.
Why were dodo birds not afraid of humans?
Gold said dodos exhibited no fear of humans when people reached Mauritius in the 1500s. They had no natural predators on the islands before humans arrived. Because of this, sailors herded the birds onto their boats for fresh meat later in their voyages….

Is it possible to grow a dinosaur?
While dinosaur bones can survive for millions of years, dinosaur DNA almost certainly does not. But some scientists continue to search for it – just in case. So it looks like cloning a dinosaur is off the table, but an alternate way to recreate the extinct animals would be to reverse-engineer one.
Are any dinosaurs alive today?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
