Importance of good environment and how it is important to our life
Answers
Answer:
The environment is an important issue even when society is faced with economic crises, wars, and unending social problems. It matters because Earth is the only home that humans have, and it provides air, food, and other needs.Humanity's entire life support system depends on the well-being of all the species living on earth. This is commonly referred to as the biosphere, a term coined by Vladimir Vernadsky, a Russian scientist in the 1920s. Biosphere refers to one global ecological system in which all living things are interdependent. Within the overall biosphere or ecosystem, there are smaller ecosystems like the rainforests, oceans, the desert and the tundra.

Living and Non-Living Parts
An ecosystem is composed of living and non-living parts, whether it is terrestrial or aquatic, explains the book Valuing Ecosystem Services: Toward Better Environmental Decision-Making available through The National Academy Press. The non-living parts are the soil, water, air, and nutrients, and living elements are plants, animals, micro-organisms, and humans. A healthy ecosystem has all the chemical elements and nutrients circulating in a cycle while supporting millions of species. The myriad of species all help in the process of cycling elements when they produce food, eat, go about their lives, and even through their deaths. In this process a variety of goods and services are created that are useful for humans.Food Chain
The food chain is an example of a useful part of the ecosystem. Encyclopedia Britannica explains that plants use sunlight, water, and elements in soil and air to create food for themselves. They are in turn eaten by animals and micro-organisms. Humans are the top of the food pyramid in any ecosystem because they use plants and animals for food. Earthworms and small insects, like bees pollinating plants, are all part of the environment without whom the food chain would be broken. World production can be gauged when one considers that 2,533 million tons of cereals alone were grown in 2015 according to Food and Agriculture Organization of the United Nations (FAO) in the first Summary Table.
Saving the environment is not just an issue anymore. It is a survival truth. Individuals, organisations and governments need to come together and join hands to protect what is left of our planet so that the future is not wiped out before it’s time for a curtain call.
Experts say that proper handling of waste materials, such as reusing or disposing of them properly, should constitute an important part of our efforts to preserve energy and protect the environment. Countries worldwide should use less coal and more reusable power like hydro or solar power.
Let us plan our cities according to the available water resources and not avail water for too many homes that have been crammed into development. Saving energy reduces air pollution and greenhouse gases. The less we pollute our environment, the more we prevent global warming. Let us check the seas from rising and submerging our lands.
Increasing number of organisations are being formed to prevent the planet from premature extinction. More and more corporates have joined the race to save the planet. We can simply begin by buying recycled products for our office, home or school. The greater the demand for recycled products, the more these companies will be encouraged to add recycled material to their products.
We can also make simple changes, like using reusable bags and containers. We should try and conserve electricity by turning off the lights, TV, or other electrical appliances when not in use. Use cold water in the washer whenever possible.
Buy less disposable products. Ban plastic. Buy more fuel-efficient cars (such as a hybrid or electric) and recycle your engine oil. Use public transit whenever possible. Let us walk more and drive less to conserve fuel and prevent auto-emission.
We should avoid littering our roads and highways. And prevent others from doing so. Always dispose your litter properly. Littering is not just bad for the environment, it is also an offence carrying heavy fines.
We use more organic fertilisers. Our farms need less pesticides and more organic methods.
Plant trees to improve air quality. Take a stand against deforestation. Losing our rainforests means losing millions of trees that would otherwise be cleaning the air for us. Let’s teach our children to respect Nature
