Protecting animals—as well as the oceans, forests, and grasslands they inhabit—will help safeguard the future for all species , including homo sapiens.
Why is it important to protect our rare animals?
Ecological importance
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 are animals so important?
Animals are our companions , our workers, our eyes and ears, and our food. They appear in ancient cave paintings, and on modern commercial farms. We have domesticated some of them, while others remain wild and are sometimes endangered by our activities.
What is the importance of animals in human life?
Animals play an important role in many people’s lives. In addition to seeing-eye dogs and dogs that can be trained to detect seizures, animals can also be used in occupational therapy, speech therapy , or physical rehabilitation to help patients recover.
How does animal extinction affect humans?
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.
How many animals are endangered?
Over 7,000 species around the world are considered endangered. That number doesn’t even include the plants, animals, and other life-forms that are listed by some scientists as vulnerable, critically endangered, or extinct in the wild—all rankings that mean a species is inching closer and closer to ill-fated extinction.
Why we shouldn’t 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.
How pets improve our lives?
Pets, especially dogs and cats, can reduce stress, anxiety, and depression , ease loneliness, encourage exercise and playfulness, and even improve your cardiovascular health.

Can you live without animals?
Originally Answered: Can humans survive without animals? Unfortunately not , as animals contribute to nature in ways that we will never be able to.

- wool and hair for clothing, ropes and tents.
- hides and skin for leather.
- meat, milk, eggs.
- bones, hooves and horn for a variety of uses.
What are the causes and effects of animal extinction?
Humans can cause extinction of a species through overharvesting, pollution, habitat destruction , introduction of invasive species such as new predators and food competitorsoverhunting, and other influences. Explosive, unsustainable human population growth is an essential cause of the extinction crisis.
What will happen if animals go extinct?
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 . Widespread starvation combined with lack of decomposition would cause rampant disease.
What are the effects of wildlife extinction?
Consequences of species extinctions at local or regional scales. Species extinction at local or regional scales implies in general a decline in species richness (number of species) and a decline in biodiversity . There is strong evidence that species richness in an area enhances ecosystem productivity and stability.
How many animals go extinct every day?
Scientists estimate that 150-200 species of plant, insect, bird and mammal become extinct every 24 hours. This is nearly 1,000 times the “natural” or “background” rate and, say many biologists, is greater than anything the world has experienced since the vanishing of the dinosaurs nearly 65m years ago.
