Why is nature so important to humans?
It underpins our economy, our society, indeed our very existence. Our forests, rivers, oceans and soils provide us with the food we eat, the air we breathe, the water we irrigate our crops with. We also rely on them for numerous other goods and services we depend on for our health, happiness and prosperity.
What is the relationship between humans and nature?

Why are humans important to the environment?
Humans need to interact with the environment to obtain our food, water, fuel, medicines, building materials and many other things. Advances in science and technology have helped us to exploit the environment for our benefit, but we have also introduced pollution and caused environmental damage.
Which is a threat to environment?
Twenty-first century threats to our environment—including invasive species, diseases, pollution, and a warming climate—are putting wildlife populations at risk. The National Wildlife Federation unites Americans addressing these environmental threats and protecting our wildlife and their habitats.

What is the important of nature?
We need Nature for food, water, to regulate the air that we breathe, to control water levels, to keep us sane, even for all the raw materials that underpin our lives. Nature isn’t important to Man, it’s essential. it also helps oxygenate our air.
Why is environmental issues important?
