Wild forests and grasslands would die because they are adapted to rely on animal decomposers as well as pollinators and seed dispersers.
This would cause abrupt loss of rainfall, atmospheric change and climate change..

There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption. Through the activity, students will create a list of reasons why animals can become extinct.
Why is it important to save animals from extinction?
Healthy ecosystems depend on plant and animal species as their foundations. 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.
Why would bee extinction affect us?
Pollination is where insects move pollen from one plant to another, fertilising the plants so that they can produce fruit, vegetables, seeds and so on. If all the bees went extinct, it would destroy the delicate balance of the Earth’s ecosystem and affect global food supplies.
Why shouldn’t we save endangered species?
Experts have a simple answer: if we don’t invest money into saving endangered species now, we will have to invest far more in the future. For example, if there are no bees, food will become way more expensive, and if vultures go extinct, cases of rabies and an increase in medical expenses are inevitable.
Will humans go extinct?
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.
How does extinction of animals affect humans?
While extinction of animal species is part of the natural process of evolution, the expansion of the human species has led to significant increases in the extinction rate. Because humans share ecosystems with endangered species, our quality of life and our survival is linked to them.
What are the effects of extinction?
They may carry disease, prey on native species, and disrupt food webs. Often, they can out-compete native species because they lack local predators. An example is described in Figure below. Over-harvesting of fish, trees, and other organisms.

How are humans affected by extinction?
Medical Studies. Animal extinctions may also rob humans of valuable medical advancements. … Each species that vanishes may hold the key to any number of medical breakthroughs, and the loss of these resources could prove a terrible blow to humans.
What could be the major cause of wildlife extinction?
Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. Dinosaurs, for instance, lost their habitat about 65 million years ago. … Development can eliminate habitat and native species directly.
