What if there was no human on Earth? Doughty hypothesizes that without humans, elements would be more evenly distributed across the landscape. This would mean more fertile soil, which would cause ecosystems to be more productive. “If the elements are more patchy in ecosystems, the productivity is going to be more patchy,” Doughty said.
How many years does the Earth have left? This is expected to occur between 1.5 and 4.5 billion years from now. A high obliquity would probably result in dramatic changes in the climate and may destroy the planet’s habitability.

how does an animal become extinct?
The main modern causes of extinction are the loss and degradation of habitat (mainly deforestation), over exploitation (hunting, overfishing), invasive species, climate change, and nitrogen pollution.

We may lose all the plants that bees pollinate, all of the animals that eat those plants and so on up the food chain. Which means a world without bees could struggle to sustain the global human population of 7 billion. Our supermarkets would have half the amount of fruit and vegetables.

how do humans cause animal extinction?
Humans also cause other species to become extinct by hunting, overharvesting, introducing invasive species to the wild, polluting, and changing wetlands and forests to croplands and urban areas. Even the rapid growth of the human population is causing extinction by ruining natural habitats.
should we recreate extinct species?
When the species was lost, the forests lost the main driver of their regulation cycle and have never been the same. Reviving extinct keystone species, then, could help us preserve biodiversity, and, possibly, the ecosystems as a whole.

how will the extinction of tigers affect the food chain?
If the feline were to disappear, there would be consequences for all the links of this chain, with the effects even influencing plants and in some areas, people (multiplication of “prey” herbivores, overgrazing, proliferation of some parasites, possible spreading of epidemics, and disappearance of new species…).

how to save extinct animals?
Scientists tell us the best way to protect endangered species is to protect the places where they live. Get involved by volunteering at your local nature center or wildlife refuge. Go wildlife or bird watching in nearby parks. Wildlife related recreation creates millions of jobs and supports local businesses.

Megalania skull, at Museum of Science, Boston One theory of how Megalania became extinct is that after Diprotodon and Procoptodon died off, there was not enough food to sustain such a large reptile, and slowly the population died to extinction.

why are amphibians going extinct?
Habitat destruction, non-native species (predatory fish, bullfrogs, fungus, pathogens), climate change (alters temperature and water levels), pollution and diseases (especially chytridiomycosis, caused from the chytrid fungus) all have been shown to contribute to worldwide amphibian declines.
