Question

Please answer.Better if a bit big in a proper form(need for assignment)

Answer 1

Forests are the 'lungs ' of the earth because they supply oxygen to the atmosphere.
they are rich in flora & fauna & form the home of rare species of plants & animals.
Trees and forests have always been a life support system, not only for humans, but also for wild and domesticated plants and animals. Trees and forests protect the land from erosion. They protect homes, farms, and coastlines from strong winds and waves. They make soils fertile, keep air, streams and lagoons clean and clear, and provide habitats and food for animals. Trees also provide us with food and countless other products that would either be too expensive to buy or impossible to import from overseas.

forests give us 5 'f's, in the form of food, furniture, fibre, fertiliser,& .fuel
food--in the form of fruits, nuts, animals & also medicine.
Forests supply the raw materials for the lumber, plywood, paper, packaging and other wood-based materials that are staples of modern life
forests are sources of clothes, resins(,rubber, gum )
the animals & plant wastes form natural fertilizers,
the trees help in absorbing CO2,& replenishing O2.thus purifying the atmosphere, & reducing pollution.
the trees check soil erosion, bring in rains, help to conserve ground water
Due to population boom, there is an increase demand for many of the commodities. This has led to deforestation;, forests have shrunk to give space for agricultural lands, construction of factories& houses.
Animals, birds are becoming extinct due to loss of shelter &vegetation
fertile lands are becoming barren due to scarcity of water & erosion of top soil;
Excessive floods & forest fires also destroy forests.
this has led to an increase in temperature which is now referred to as global warming.
So it is essential preserve forests by reducing cutting of trees help in afforestation programs ,finding alternative sources for forest products, reducing wastage ,recycling & reusing processes

Answer 2

To provide a vital habitat for wildlife. A native hedge plays a part in the survival of butterflies, moths, dormice, hedgehogs, birds, insects and bats.

Trees and shrubs can be educational. Many schools are now developing nature areas which in turn is making the next generation more aware of the environment

To suppress noise pollution, an ever increasing problem in urban environments.
Landscape and aesthetic value, can enhance an otherwise unattractive building or site.

Timber or fruit production. This does not have to conflict with conservation issues, with careful management, replacement and natural regeneration more aware of their environment.

To stabilise soil (e.g. hills and riverbanks), where trees have been felled on steep banks, soil erodes and with the absence of trees causes whole banks of soil to wash away. Trees can also protect soil from hot weather, preventing it to dry out too quickly.

To act as a windbreak, shelter belt and visual screen.

Answer 3

The Amazon Rain Forest produces the majority of the world's oxygen.
Cutting and clearing is destroying that.
You could research that.

Answer 4

it provides us about half of oxygen and without oxygen we couldn't survive

Answer 5

greeny the world.... longer the world........
