To preven extinctions of plants and animal species.
Maintain a stable & balance ecosystem. This prevents the disruption of natural cycles such as the water & carbon cycles and prevent global warming.
Maintain a large gene pool. Wild plants and animal posses favourable genes in which we can cross-breed to ensure better quality yield.
Ensure the conservation of marine life, a source of food for humans.
Conservation is of scientific value. The study of wildlife provides useful information to humans. [Learning about evolutions from studying wildlife]
Conservation preserves natural scenery and wildlife for us to appreciate. Maintains natural resources for outdoor recreational activities.
Maintain the biodiversity. Rainforests, esp Tropical Rainforests house a large number of species of organisms. Many tropical plants serve economic importance as they are sources of raw materials for the different industries.
(a) Rattan is used to make furniture. Rubber from latex of rubber trees are used to make tyres. Fibres from cotton are used to make clothes while fibres from coconut husks are used t make ropes.
(b) Tropical plants provide raw materials for medicinal drugs/natural insecticides. I.e.: Quinine, an anti-malaria drug from the bark of Cinchona, and morphine, a pain-surpressing drug derived from the sap of the poppy plant. Certain poisonous animals may also contain chemicals that have medicinal value.
(c) Provides us with food. Rice, pineapple and bananas are examples developed from rainforest plants.
